Hi, I have this Vibration /shutter. Its been doing it for 5 months now. I'm not sure how it started or really when but I think it may started from when I had to give it a lot of gas from not getting hit from someone?? I also had to have the throttle body replaced before then too. Its a 03 4.7v8 with 36 thousand miles on it. I have taken it to the dealer 3 times. Had the 30,000 tune up done also. I also get engine Vibration sitting still with in park and rebbing it to 1300rpm -1700rpm that's were it really like to vibrate in that area. I can feel it in the steering wheel and pedal when driving as well. So I don't know what it could be. The dealer just says it normal, the maint guy said it feels like a Jeep. I think it may be the Transmission ?? That acts up too, when I shift from R to D it will want to die some times??? some times when it shifts from 1st to 2nd or 2nd to 3rd I get a shutter.Will the Transmission make the car Vibrate /shutter when driving and sitting in park?? Any ideas? I don't know what I should try next. I hate to drive it on long trips because the Vibration /shutter is so annoying and maybe doing damage to something. Other than that the engine runs strong.
My 2004 jeep grand cherokee is equipped with a quadratrac II transmission. It has recently began to lock up on me. Earlier today it locked up completely. I checked the transmission fluid level and it is good. Is this a problem with the transmission or possibly the 4 wheel drive?
When I start my 2006 Jeep GC (less tha 30k miles) and start moving on a cold day it's fine, but the very first time I stop at a light or stop sign, when I give it gas the engine revs and the vehicle barely moves. Giving it more gas doesn't help, you have to let off and proceed slowly untill it resolves itself, usually within 5 to 6 seconds. Once it does this it usually doesn't occer againg until the car sits overnight, but on occasion it has happen again even when the car warms up. Even though it's auto trans with full time 4WD, it's as if the clutch was slipping on a standard transmission vehicle.
A friend has a 2004 JGC V6 special edition. She says it is shifting late (5000 RPMS) in all gears regardless of demand, load or speed. She also stated it is shifting rough/slow when it does shift. No other problems with the car. I had her check the transmission fluid and it is full. I am going to have her change the fluid and filter but thought I would post to see if anyone had experience with this problem and it's possible cause (TCM, TCC solenoid, etc.). I am unfamiliar with Jeeps but I am a solid shade tree mechanic (mostly Audis, Volvos and Chevys). My only Chrysler was a Eagle Talon AWD (Mitsubishi engine/design). Thanks in advance.
My Malfunction Error message came on during my drive home. I have been having problems with what i think is the transmission not wanting to shift correctly. It is equipped with the TPS shifting and every so often it will not let me downshift. I went to check the transmission fluid, however there isn't a dipstick, just a cap. Any suggestions?
Hope you found your problem by now since it has been months since your post. I'd just like to say that in my experience - never listen to a transmission mechanic - unless he's family. Anyone I've ever known with a transmission problem gets bad news when they take it to transmission specialist and most of the time when your car wont shift or is making noise its either in need of mere adjustment or more fluid.Your transmission adjustment cable is right next accelorator cable on your throttle body and make sure if your having someone else change your fluid that it is the right one cause you'd be surprised how it will change the feel of the shift. Good luck.
To check your engine mounts - pop your hood - put the truck in drive while holding the brakes tightly(make sure no one is infront of the truck when you do this) and give it some gas. If the motor moves moves side to side more than 2-3 inches or clunks- the mounts are bad.Almost everytime you have a problem like this though unless it happens suddenly while on a trail its got to be simply out of tune and the trick is to find what sensor or wire etc.
My engine vibrates at idle. I have no check engine light and have just passed inspection. It starts well anytime of year but seems sluggish to respond and is a little low on power. I have tuned it up but that had no effect. One clue might be it runs a little better on 93 octane rather than regular. Thanks.
hey did you ever find the solution to your problem i have a 94 jgc with the same problem all the gears change fine it just doesnt kick into overdrive it does it once in a blue moon when ive been driving for a while the damn mechanic says i need it rebuilt for $900 i dont think its that serious a problem to do a rebuild so any help will be appreciated thx
I found out that its one of two things, both require trans pan removal its either the Govenor pressure sensor(my problem)or the govenor pressure solenoid not difficult to change either one there are a few sites I found with step by step instructions and photos the cost new on these items are about $100.00 each from NAPA I got mine used from a junkyard either way its cheaper than a $900.00 rebuild! My mech. says this is a common Chrysler problem the 42RE is a tough tranny most of the time its just somthing simple like sensors or fluid levels filters solenoids ect. hope this helps
I had a similar problem with my 2006 grand cherokee. It would ocassionally have the check engine light come on and then would not shift properly. TPS shifting would not work and it would either not let me out of third gear and one time would not allow me to exceed 3000 RPMs. I brought it to a transmission specialist and it turned out that the sheild over the wire harness had worn away the insulation of a few of the wires causing a short. Got it fixed along with a transmission service (at 50K miles) for $450. Glad I was able to avoid going to the dealer and ending up with a new transmission.
I have a 2004 limited with the 4.7 HO motor, it has 98,000. I just started having a issue that is inconsistent, and I was wondering if anybody could help. Sometimes the tranny is not shiffting out of 2nd or 3rd, RPM'S go up but it will not shift. If I let off the gas and cruise for a bit it usually then engaes the next gear. Also when this is happening I hear a thumping sound and a slight jerk as it down shifts (0nly in the low gears). As I said it does not always happen and tempature does not seem to make a diffrence. It runs fine on the highway no problems or loss of power. It's like it's not shifting at the proper time up or down when cruising at low speeds. Then other times I get in and it's fine. I checked the fluid level and it is fine. No burnt smell or dirt, nice and clean. This vehicle has been a thorn in my side since I bought it (20,000 miles). It's a piece of SH*T. It has always been well maintaned and never beat on. Used as a secondary vehicle. Every time I turn around I'm dumping money into it. Significant money over the years. I will never by another Jeep again. And I have owned many. Any help would be greatly appreciated, THANKS! Oh and one more thing every time I start it it runs up high (2,000) and then slowly drops off to where it should be. A little jumpy at first, then calms down. I know this is a seperate issue, could it be a sensor? That's what I was told.
i would change the tps and see if that dont fix all your problums as the trans shift points are deriver fron that sensor same as fuel mixture lot cheaper than pcm
Hey all, I have a 1995 Grand Cherokee ZJ Laredo L6 4.0 engine. Recently I have been having trouble w/ the transmission (automatic) shifting and it shutting off the auto O/D upon start-up. Turning over the car will start, there will be a definitive "click" sound and then the O/D Off light turns on, and when I hit the button, the light stays on. When going to accelerate, it takes until about 2200 rpm before it moves and gets speed, and then wont go over about 60 mph w/o being at about 2800 rpm high rev'd. I took it to a mechanic who said 1st gear was completely sheared, another, one replaced the input/output sensors on the transmission to solve (which didnt work) because the problem is sporadic and random at best, can never determine when. I have noted tho if it does turn on and the problem is there, starting out in 2nd and then shifting to D helps accelerate better, but I wanna clear this problem up, any suggestions? No check engine light code (light is never on) is 42RE auto trans, approx 185K on it. Thanks
Dear all, I have fixed four new Perilli 245/65 R17 ATR tires for my Hemi JGC 2005 but I noticed that they are too noisey at the inside while driving. I was told that because they are off-road hard tyres. Can any one advise me what are a better performance and more quite/smooth on-road tyres for this Jeep. I'll be able to resell them over here with minor loss.
I've had Goodyear Fortera SilentArmor 245/70/R16 tires for my '98 GC and I absolutely love them. I upgraded to these when they stopped making the Wrangler HPs. I noticed the smoother/quieter ride on the highway immediately, and they handle really well in rain/snow. I wouldn't bother with the TripleTreads, since you're sacrificing performance on anything except dry, smooth pavement.
I have full-time 4WD, but the treads have lasted a while, and they will for you as long as you rotate them often. When I get new tires later this year I will be getting the exact same ones again. Good luck
my sons 95 grand cherokee quit moving. had it towed home husband changed filter and fluid(atf4) worked great for 10 miles now acts like it shifts into neutral and won't move. let it sit for awhile goes again then same thing happens. will reverse and forward enough to get it mowed around but can't be trusted. any ideas
I'm having the exact same problem that you are. Have you been able to figure out what it is? I have a 95 Grand Cherokee Laredo 4.0L AutoTrans 42RE 220K miles.
hello i have a 2002 jeep grand cherokee that i have changed fluids for trans and filter. but the problem is that when i take off in normal drive it seems like its stuck in 2nd or 3ed. gear i am a generall mechanic but these new trans are hard to diagnose. i see a lot off problems similar to mine maybee cylenoid pack on trans. or servo for 1st gear i dont know but it would be helpfull if some one could tell me something . thank you. j.d P.S also when i shift manully from 1st. to 2nd. and then drive works fine . and then come to a stop wont shift back up into 1st. alot off problems with other peoples vehicles like mine that are simular. J>D
Hi. I'm having a very similar problem to yours, and wondering if you've been able to diagnose your problem? I have a 2004 grand cherokee, and sometimes when I roll to a stop, it shifts into second gear (just before coming to a complete stop), so when you take off again, it takes off in 2nd gear. After you get up to 20-30 MPH, it then shifts into 3rd, and everything's fine again, until I stop, and then the same thing all over again. Any ideas or information for me? Thanks....M.T.
97, bought it new, luv the truck, have religiously maintained it. At 110k miles, when shifting from 1st to 2nd ... feels like a pulsating feeling, kind of jerking, goes into 2nd ... and from there everything is fine. Recently, in last couple thousand miles, full fluid & filter changed. Any clues? Saw one other message about TPS, what is TPS?
I recently purchased a 2006 JGC 4x4 automatic about two weeks ago. The vehicle has 59K miles on it.
After 2-3 days, I noticed that the shifting was somewhat erratic - it is difficult to explain the symptoms, but I will try.
When accelerating, and the vehicle reaches about 35-40 MPH, and the RPM is around 1500, it seems to "stick" or shudder before accelerating more - as if the transmission is stuck. If I am going up a hill, it will sometimes shudder or surge a bit, as it gets through this area.
Also, around 60-65 MPH Ive noticed a similar surging.
Often, it seems Ill be driving along, and I will need to increase my speed very slightly, so I slightly depress the gas, and the vehicle seems to stick and start to lost power and surge - again, it "feels" like the transmission. It seems, especially around these problem points, to shift inefficiently at points where power is lost.
In general, the driving experience is awful, because it seems like I have to keep fighting the transmission - I have to accelerate more to get past these sticky spots, and then Im going a little too fast, so I have to coast and slow down, while the transmission has to jump around while doing so, and it never seems to shift where I would shift if I was driving a manual.
There are no engine lights, no warnings.
I did take it to a "transmission specialist" who test drove it with a scan tool, and he said he did feel a "slight slippage" (he thought) and did indicate he eventually saw a scan code indicating a slippage. He was going to start dissassembling the transmission, but at that point, I decided to take it back to the (Mazda) dealer, and have them try to diagnose it and work with the warranty company directly. (They told me to bring it back next week)
But after browsing through some of the forum, I have seen a few posts mentioning similar symptoms - specifically one that indicated nearly identical symptoms at 35-40 MPH and 60-65MPH that turned out to be a "Throttle Position Sensor"
My question is - if it -IS- the throttle position sensor, would occasional "slippage" scan codes show up, without an engine light warning?
The problems are just subtle enough that its difficult to get a service tech to really understand them, and I am afraid of having to go through months of trying to get someone to recognize the problem, and not just say "Jeeps just drive like that" which I know is not true (this is my 3rd)
The jeep is great, otherwise - like new.
I have an extended warranty (Easy Care/Total Care) that should cover things - assuming someone actually can diagnose it correctly.
Does anyone have any advice for getting this diagnosed and repaired competently?
How much does it cost to replace a TPS, if I was willing to just "try it"?
I dont know if you are still around, troll157, but I would like to ask you some more questions about your solution of changing out the O2 sensor and TPS.
My JGC is having difficulty at precicely those two spots.
I am having the exact same problems and I have tried to narrow it down. I bought a Actron CP9125 and hooked it up to my 2005 Jeep grand cherokee. It told me I had a P0700 and U0404. Code P0700 = Trans control malfunction. Code Uo404 = Invalid data received from control module gear shift. This means Trans Control Sys malfunction. From what I have googled so far that means that there is a problem with the computer that shifts the tranny. I have seen two solutions. Replace the shifter bezel in the jeep (makes the most sense - replace the computer) and replace a few filters in the tranny (seems like BS). I did find that both of these fixes are in TSB's (Technical service bulletin) 21-016-06a and 21-007-06. I would think it would be smart to do both actions. I am not sure if either of these are covered by the original warranty 36K / 3 Year or the 7/ 70 K drivetrain. 3/36 should cover it. I of course am at 50K. Does anyone know if the drivetrain warranty covers a shifter bezel or TCM? I am going to go into the dealer and see what they tell me. I have a feeling I will be going somewhere else to fix it since dealers usually try and get you. BTW, I had a high whining noise at about 60 mph when I had 30K on the truck and they replaced the whole drive shaft under warranty (this is under a different TSB I think). I believe this will be the last piece of junk jeep I ever buy. :mad: Cash for clunkers anyone?
My problem: 1994 Jeep with 155k miles had a new tranny installed less than 15k ago and now when I take off from park and if I get on it a bit it won't shift The engine revs up but the tranny just kinda hesitates and I have to let off the gas to get it to shift. Going up a steeper hill at 55 it will try to kick down but once again just kinda hesitates there will lose 8-9 mph by the time I get to the top. Talked to place that put in tranny and of course they want mega $ just to check it out because the warranty in up. But the guy said maybe the governor pressure sensor or solenoid even the crankshaft postion sensor? Any ideas? Thanks
I've 2005 Grand Cherokee Laredo 4*4 - 51K miles. Last weekend I couldn't shift to anything - it stays N.
I took it to a service, he said the transmission needs to be changed and it has European made transmission. He told me that it'll cost around 4.000 USD!! :mad:
Any suggestions will much appreciated... I'm in NY - Queens and if you can suggest an honest service, it'll be much appreciated...
$4000 is a little on the high side. My 2005 4x4 automatic would cost $3400 to replace the transmission.
Its in the shop right now - fortunately I have an extended warranty that I bought last month, that -should- cover it (or most of it)
If your jeep only has 51K miles on it, it should still be covered under the original manufacturers 70K warranty, if you have all of your regular service receipts to show youve maintained it on schedule.
My jeep was a former rental, so the 70K waranty didnt apply, and I needed to get the extended warranty.
Thanks for the answer... I bought the car last year - it was 48K miles at that time... Is there any chance that still it's covered by 70K warranty? How can I check it? any ideas? :confuse:
I noticed a problem with my transmission seems like it is slipping and is getting worse. It does not happen all the time but has happened 3 times over the past 2 weeks and only happens when I am traveling 45 to 55 MPH. The car feels like it is going to stall and then it has a slipping feel for the next few minutes. I bought the car new in 2000 and was consistent in having all the service checks done. Vehicle now has about 125,000 miles and I have no intention of replacing it but I need to be sure the problem is diagnosed properly and not just have someone want to put in a new transmission. I am not mechanical and need some ideas on what could be the problem. For starters, is it the transmission?
Ok Friends, I have done the research and read the posts, The Trans "slips" and will not shift into overdrive, sometimes will not shift when it is supposed too. I hope it is the TPS. Now I just need to know where it is and how do I change it? Please tell me if you have done this fix so I can get the old lady off my back and out of MY Tahoe!!! :mad:
I have a 2005 JGC 4x4 with the 5.7 L and recently, yesterday afternoon, I was out picking up lunch and when I was pulling out of my parking space the transmission did not engage immediately. The engine reved up to about 4k rpm's and after about a 5 second hesitation it finally engaged. This occured the next few times I had to stop and start again; didnt notice any kind of slipping while driving, just after stopping. I took the jeep to the closest place I could find, unfortunately it was a dealership, and after reading the computer codes and changing the transmission fluid/filter they have come to the conclusion that the whole transmission needs to be replaced, go figure. They are trying to tell me it is going to run around $4500 to fix, but I dont see how the transmission just goes out after showing no warning signs other than what happened yesterday. I obviously dont have an extra $4500 laying around; anyone experience anything similar and find a less costly fix?
I have a 2007 Laredo that I just bought in November of 2008. Twice in one month I came out to start my Jeep and it wouldn't start. It says "Transmission over temp". It won't turn over and jumping the battery doesn't help either. Does anyone know why this is happening. I took it to the Dealer and they can't find anything wrong with it. Help!
Mytylerjr, did you ever get a proper diagnosis? I have an '06 JGC 4WD with the EXACT same symptoms. Also has the same mileage....59k. If you ever got to the bottom of it, It'd really help me out to hear what the problem was! Thanks.
It turns out that some major bolt to the master output shaft had been improperly tightened in the past (the transmission mechanic said he suspects that it was when the vehicle was first assembled(!)) and simply worked its way loose, got stripped and was alowing the master output shaft too much travel and shaking, and things got stripped.
The gears themselves were fine (no wear after 59K) but the master output shaft and collar (and torque converter) were all damaged from the tranny moving around too much.There were other contamination issues. The warranty company sent two inspectors out to see the damage.
In the end, I needed to have the entire transmission replaced, for $2750.
Since the failure started just 4-5 days after I bought the vehicle, AND I bought an EasyCare "Total Care" extended warranty, I would have thought it was covered.
EasyCare however, balked, and said "Too soon - must have been preexisting, we're not going to cover it" and the dealer said "the jeep was sold "as-is" with a 3rd party warranty - you need to work with the warranty company" - I am apaprently out of luck.
Obviously I have been complaining to both parties, and I think they may be actually reconsidering my claim, and -may- still cover part of it. I am still waiting to hear back from a manager at EasyCare, and the dealer claims they have heard that there is a "Maybe 60% chance they will cover some of it as a special circumstance" - but I am still waiting. I very much hope they cover all or most of it - or I will be detailing this experience onthis and several other forums, to make sure people know.
The good news is, after replacing the tranmission, the jeep runs GREAT.
Im sorry that I dont have a magic, cheap fix to reveal to you. I wish I had had one.
I just bought a 89 JGC and the transmission just started to make a popping noise as if it were hitting somethoing else in the transmission box. It makes the noise in drive, reverse, 2wd, 4h, and 4l. I have cut the engine off and left it in neutral and when i pushed it it still popped. Any Comments Or Suggestions On What This May Be?!?!?!?!?!?!?!??!?!?!
Since you hear the "popping" when you're in N (i.e., transmission disengaged), that suggests to me that it is not your transmission at all. Does the sound change with vehicle speed, turns, etc.? Please provide more information.
I have a 2007 loredo with the same problem!!! The thing that sucks is, it doesn't do it all the time, just once in a while. so you take it to the dealership and it starts right up so they don't see a problem. Last time they changed the ignition switch and that didn't work. I am going in for round 2 today. Any suggestions???
Hi 'jeepcreep', did you fix this problem. My 98 GCL got stuck with no reverse - couldn't even push it back, so towed it back with locked wheels. Can't work out if it's in the transfer case or the auto transmission. As you say, I can turn the shaft to go forward but not backwards. I'd appreciate some help on this. :shades:
Ok, I have been read all of those and I see the same problem what I have on my 94 Jeep G.C. Laredo. I tried replace TPS and CSS. Nothing change. So I decided I replaced the E.C.M. and its WORKED!!!!!!!! I m mechine all my life.
E.C.M mean Engine Control Module ! I removed bad E.C.M. and replaced it. SMOOTH and DRIVE! E.C.M. is control for Engine and Transmission.
Hey there. I have a 96 sport with an auto transmission that is having troubles right now. It doesn't happen every run but once in a while it's like it's starting in 2nd gear. There is virtually no power on initial acceleration but once it slowly picks up speed it seem to be fine at higher speeds shifting into subsequent gears until I slow down to a stop or near-stop and try to accelerate again. Additionally just recently it accelerated normally from a stopped possition but it wouldn't shift out of 1st gear even with RPM's upwards of 6000. I had to pull over and move the shifter through the possitions to get it to go into other gears.
Again both problems are intermittant and most days the tranny is fine. Just curious what's going on. I plan to drop the pan and do a gasket and filter swap in the event there is some sort of blockage in the filter or pan somehow affecting the shifting. But aside from expensive tranny work I'm at a loss as to what's happening. I really need this thing to last me a few more years if possible.
i would change the tps and see if that takes care of the prob AS the tps tells the trans where the throttle is at dont use cable to tell what posion the foot feed is at
Thank you for the response but you'll have to clearify for me... whats a TPS? I love working on my Jeep and my old Pontiac but I'm not always familiar with the lingo.
And in case anyone is following this question, I replaced the tranny fluid, gasket, and filter and I am still having the same issues. The fluid was at least 50KM old but had no burnt smell and was still clear. The magnets in the pan were intact and had only very small almost graphite-like particles attached to it (no obvious metal filings). The filter looked clear and a visual of the tranny guts seemed fine too.

I have this Vibration /shutter. Its been doing it for 5 months now. I'm not sure how it started or really when but I think it may started from when I had to give it a lot of gas from not getting hit from someone??

I have fixed four new Perilli 245/65 R17 ATR tires for my Hemi JGC 2005 but I noticed that they are too noisey at the inside while driving. I was told that because they are off-road hard tyres.
Can any one advise me what are a better performance and more quite/smooth on-road tyres for this Jeep. I'll be able to resell them over here with minor loss.

I have full-time 4WD, but the treads have lasted a while, and they will for you as long as you rotate them often. When I get new tires later this year I will be getting the exact same ones again. Good luck
Today wouldn't shift into park, RND were fine. I drove it home.
Now won't shift out of R. Can't get it into neutral to start it. Shifter will move down to N and D, but remains in R. Will not go into P.
Thanks for any ideas. :confuse:

Going up a steeper hill at 55 it will try to kick down but once again just kinda hesitates there will lose 8-9 mph by the time I get to the top. Talked to place that put in tranny and of course they want mega $ just to check it out because the warranty in up. But the guy said maybe the governor pressure sensor or solenoid even the crankshaft postion sensor? Any ideas? Thanks
I've 2005 Grand Cherokee Laredo 4*4 - 51K miles. Last weekend I couldn't shift to anything - it stays N.
I took it to a service, he said the transmission needs to be changed and it has European made transmission. He told me that it'll cost around 4.000 USD!! :mad:
Any suggestions will much appreciated... I'm in NY - Queens and if you can suggest an honest service, it'll be much appreciated...
many thanks in advance...
where's the service that took care of your jeep? I'm in NY and need a honest one for my transmission problem...
many thanks...
Its in the shop right now - fortunately I have an extended warranty that I bought last month, that -should- cover it (or most of it)
If your jeep only has 51K miles on it, it should still be covered under the original manufacturers 70K warranty, if you have all of your regular service receipts to show youve maintained it on schedule.
My jeep was a former rental, so the 70K waranty didnt apply, and I needed to get the extended warranty.
many thanks...
I have done the research and read the posts, The Trans "slips" and will not shift into overdrive, sometimes will not shift when it is supposed too. I hope it is the TPS. Now I just need to know where it is and how do I change it? Please tell me if you have done this fix so I can get the old lady off my back and out of MY Tahoe!!! :mad:
So you were able to start it? My guess would be that the transmission fluid sensor is misbehaving.

It turns out that some major bolt to the master output shaft had been improperly tightened in the past (the transmission mechanic said he suspects that it was when the vehicle was first assembled(!)) and simply worked its way loose, got stripped and was alowing the master output shaft too much travel and shaking, and things got stripped.
The gears themselves were fine (no wear after 59K) but the master output shaft and collar (and torque converter) were all damaged from the tranny moving around too much.There were other contamination issues. The warranty company sent two inspectors out to see the damage.
In the end, I needed to have the entire transmission replaced, for $2750.
Since the failure started just 4-5 days after I bought the vehicle, AND I bought an EasyCare "Total Care" extended warranty, I would have thought it was covered.
EasyCare however, balked, and said "Too soon - must have been preexisting, we're not going to cover it" and the dealer said "the jeep was sold "as-is" with a 3rd party warranty - you need to work with the warranty company" - I am apaprently out of luck.
Obviously I have been complaining to both parties, and I think they may be actually reconsidering my claim, and -may- still cover part of it. I am still waiting to hear back from a manager at EasyCare, and the dealer claims they have heard that there is a "Maybe 60% chance they will cover some of it as a special circumstance" - but I am still waiting. I very much hope they cover all or most of it - or I will be detailing this experience onthis and several other forums, to make sure people know.
The good news is, after replacing the tranmission, the jeep runs GREAT.
Im sorry that I dont have a magic, cheap fix to reveal to you. I wish I had had one.
E.C.M mean Engine Control Module ! I removed bad E.C.M. and replaced it. SMOOTH and DRIVE! E.C.M. is control for Engine and Transmission.
Again both problems are intermittant and most days the tranny is fine. Just curious what's going on. I plan to drop the pan and do a gasket and filter swap in the event there is some sort of blockage in the filter or pan somehow affecting the shifting. But aside from expensive tranny work I'm at a loss as to what's happening. I really need this thing to last me a few more years if possible.
Any help would be great.

AS the tps tells the trans where the throttle is at dont use cable to tell what posion the foot feed is at
And in case anyone is following this question, I replaced the tranny fluid, gasket, and filter and I am still having the same issues. The fluid was at least 50KM old but had no burnt smell and was still clear. The magnets in the pan were intact and had only very small almost graphite-like particles attached to it (no obvious metal filings). The filter looked clear and a visual of the tranny guts seemed fine too.
Thanks for taking the time to respond.
