    Few vehicles with 320K miles on them are worth spending a lot on for repairs. You might want to look around for a replacement vehicle for the one with the bad tranny. Otherwise, the repair costs may be more than you want to invest.

    when ever i have my head lights on, the transmition slips. only does it when the voltage guage is right in the middle. also happens when i roll down my windows. This is a work van, thank god i dont work at night. 1992 chevy van G-30 78k mi
  • wtd44wtd44 Member Posts: 1,208
    How are the battery and the alternator on that vehicle? Being a '92, it may depend more on electricity than on hydraulics in the transmission.
  • jrichman1jrichman1 Member Posts: 18
    about 2 yrs old. i know itws something with electricity because it only happens when jiuce is used!

    I have 98 honda accord V6 with 130,000 miles. It shifts hard, until it is warm. It does take longer in the winter to warm for obvious reasons and in the summer less time. Took it to the dealer who said "yep needs a new tranny". I then took it for a second and third opinion, from none dealers, both said there was no problem with the diagnostic test, with the transmission. The dealer said that they just drove it(cold) and came up with the diagnosis. Any idea what I should do?
  • wtd44wtd44 Member Posts: 1,208
    jrichman1-- Were it me, I'd get an electrical system diagnosis from someone who has proper equipment to do that. If the electrics are okay, then a transmission shop must be the next proper stop. Or, skip the electrical and go directly to someone who can diagnose electrics and transmissions. I would think most current transmission specialty places could handle the whole thing.
    lbrown1-- In your situation, I'd take a "philosophical" approach. With the 2005 cars now coming out, you have a 130K mile car that is seven model years old. The dealer says only a new transmission will change the behavior of the car. Independents told you that the transmission checks out okay. I would drive it until the transmission gives out, or the car dies from some other cause. Then, I'd get another car. The only alternative I would consider is to go get the next car now, and trade in the 1998. I like my second suggestion the best...
  • jrichman1jrichman1 Member Posts: 18
    is it worth it to go, because the van is only worth about 2-3 thousand trade in value. plus i own a lawncare service so i need to get a trailer within a coupe of months. do you think hooking up a triler would add to this problem?
  • wtd44wtd44 Member Posts: 1,208
    Maybe you could get an independent transmission shop to take a look, and then between you and them, you can decide if repairs would be worth the expense versus looking for a replacement vehicle.
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    I'd plug in a used transmission if you could find one with say $40K-50K on it.

    But sure, get a second opinion. Did anyone find debris in the transmission, or do some testing and get some readings?
  • jrichman1jrichman1 Member Posts: 18
    yeah i just took it to a tranny shop and they said nothing was wrong with the tranny, they said it was clean and no debris or anything. now i guess i will take it to a electric diagnostics center

    i have a 1992 lexus with 120,000 miles two days ago i noticed that when i put the car in reverse it would shake and then today i was driving and the car stopped accelerating and i noticed that when it did that the rpm feel under 1 does anyone else have this problem?
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    This doesn't sound like a transmission issue.

    The only way I can think to connect the two symptoms (and they may not be connected at all, but two separate problems) is that your engine is missing on one cylinder or running erratically at times. When was your last tune up?

    Otherwise, the two problems probably aren't connected, and I'd look for engine troubles as well as possibly a worn transmission mount, bad u-joint in the driveshaft, things like that.
  • joe3891joe3891 Member Posts: 759
    Check the induction hose after the MAF sensor for cracks, it will cause the same Symptoms.
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    You mean shudder off idle? But he says "only in reverse" which kind of kills that idea--whereas a weak motor mount or trans mount might very well only act up in reverse, which has the lowest gear ratio and hence the fastest "wind-up" off idle.
  • alcanalcan Member Posts: 2,550
    ABC's of pressure control:
    Trans mainline pressure is controlled by the main pressure regulator, which in turn is controlled by the pressure control solenoid. The powertrain control module (PCM) varies current flow through the solenoid to achieve desired line pressure based on inputs from several sensors. Primary inputs are throttle position sensor and manifold absolute pressure sensor. Secondary inputs include engine coolant temp and trans oil temp. Increasing current flow through the solenoid reduces line pressure, decreasing current flow raises pressure. Default or failsafe, in the event that the solenoid fails electrically or control is lost, is zero current flow and maximum line pressure.
    Diagnosis procedure:
    install a scan tool and monitor inputs to the PCM. If all are ok, install a line pressure gauge on the trans and see what happens when the PCM commands high line pressure, then turn on the lights and look for any change in any inputs. If the PCM is still commanding high line pressure, suspect a defective pressure control solenoid or associated wiring. If the PCM commands low line pressure (will cause the trans to slip under load), look for a skewed sensor input. If all are within normal parameters, suspect a defective PCM. This is all assuming there are no incorrectly installed aftermarket electrical devices.

    A reporter is interested in talking with a 2004 Ford Explorer owner who has experienced clunking when it goes from park to reverse when cold. This sounds like the tranny/solenoid problem some '04 Ford Explorer owners have been complaining about.

    If you are interested and willing to be interviewed on camera - please email sylvia@edmunds.com TODAY with your daytime contact info and city/state.

    Thanks!

    The Camry wont shift into overdrive when the car is cold, but does fine when the engine warms up. Also, it has dirty fluid but it doesnt smell burned, it is brown not black. Anyone know whats wrong??? The car 156,138 miles on it and just had a tune up 3 days ago....

    Thanks!

    The Accord 00 and 01 V6 transmissions are covered. I was having problems with my 2002. I came to a 2 way intersection; stopped; got half way through and my car wouldn't move. I almost got hit by 2 cars. I was finally able to put it in 1st to accelerate through the intersection. I drove it to the mechanic after almost getting into a wreck with my family in the car because of that. My check engine light was on as well as the D4 indicator light was flashing. My mechanic ran the diagnostics on it, and ran the codes through the system. He printed me out several pages sent directly from Honda. They included the '99 V6; 2000 and 2001 Honda Accord, Odyssey and Prelude and Acura, and some '03 Acura 3.2 CL and TL. All of which had an extended warrenty. I took all of this info to the Honda Dealer and they approved me to get the free transmission (I had just went over 36000 miles), but I had to pay for the labor ($500 more than I thought I should have to, but better than nothing I guess.) With this being said, if they didn't feel like the previous models and their issues were completely resolved, they wouldn't have replaced the transmission.
    I am suggesting anyone with problems to call the HOnda representative. If there are problems that can cause a wreck, injury, or death you should contact NHTSA. If NHTSA receives similar complaints and it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign. They do not get involved your problems with Honda, but it brings attention to the rising issues with this problem.
  • morehpmorehp Member Posts: 30
    Toyoman1, it depends on what exactly you mean by "won't shift into O/D when cold." Camrys of that vintage are programmed to hold lower gears until warmed up in order to speed warm up and reduce emissions and/or wear on components.

    When cold, our 1993 Camry does not shift into O/D until driven at least 50 mph for 1/2 mile or so. It has done this since new. When warm, it'll shift into O/D at 35 mph.

    However if you have noticed a change in behavior or if the car simply will not shift into O/D for a prolonged period of time you may have a problem. Changing the fluid may be a reasonable starting point, particularly if it looks dirty.
  • toyoman1toyoman1 Member Posts: 52
    I have noticed that when the car is cold that it wont shift into overdrive while at 50 mph. The RPMs will then be around three and it sounds as though the car wants to shift but doesn't. I wasn't aware of the warm up stage in the Camry... It does only do it the first 1/2 mile from the house and then it will run fine as long as the engine is warm, even if the engine is shut off. Should I get it looked at????
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    Could be a sensor not signaling the transmission that it's warm enough.
  • toyoman1toyoman1 Member Posts: 52
    Just an update... now only a few days later the transmission is shifting more violently from 3rd to overdrive. It is bucking pretty bad. Any ideas??? And is this gonna be a tranny rebuild???

    Better get a tranny man to diagnose that, hands on,toyoman1.
  • jrichman1jrichman1 Member Posts: 18
    i will be getting a trailer soon so i wanted to know while pulling the trailer do i drive in O.D. or regular DRIVE
  • alcanalcan Member Posts: 2,550
    Use DRIVE range when towing. Did you ever sort out the slippage problem with the lights on?
  • wht98wbwht98wb Member Posts: 2
    Need some advise asap. I have a '98 VW Jetta with an automatic transmission. Recently, the transmission started dropping out of drive into neutral when I come to a stop. If I press the accelerator, the engine will begin to rev then the car will jerk forward and then drive normally. No problems with reverse.
    At this point, I have had the car looked at by a VW dealership. They changed some of the fluid (as needed for checking the fluid level) and determined that the fluid level was good, and no codes are showing up on their diagnostic computer. So, they are suggesting that I have the transmission serviced ($300) to see if that will fix the problem, otherwise I'm looking at $3100 for a new transmission. But if the transmission is bad, I prefer to trade or sell the car rather than pay the money for the new tranny, so my question is, is it worth a $300 gamble to have the tranmission serviced? Can a simple servicing (replacing filter and fluid) fix a problem like my car is having? Help!
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    Sure it's worth a gamble, because a '98 Jetta with a bad automatic is essentially a flower pot, unfortunately---you can't get much for it. You might consider a used unit from a wreck. You might also consider a second opinion from a shop that knows these cars.

    I'm not sure what you mean by "dropping out of drive". Does the tachometer actually jump up to a higher rpm all by itself, or do you just mean that it slips as you give it gas? If it actually dropped out of drive, it would stay in neutral. I rather doubt you are actually in neutral.
  • toyoman1toyoman1 Member Posts: 52
    So just an update... I have checked my transmission fluid and it is brownish and looks really worn. I bought this car used about 4 months ago and I dont think it was taken care of... had alot of probs. Anyway, how much can bad tranny fluid affect tranny performance???? Thanks ahead for any replies
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    It can have a serious effect, either with friction and/or clogging the valve body. I'd recommend an oil and filter change for the trans ASAP.
  • toyoman1toyoman1 Member Posts: 52
    So today I went and had the transmission flushed and filter cleaned and the mechanic showed me the old fluid. He said "this is way beyond worn" car has 156,000 and the only time the previous owner had it done that I know of was a 60,000 mile tune up at the Dealer. Invoice was in Glove Box... Anyway the car drives MUCH MUCH better in all the gears except for 3rd to O/D. This gear change is ALOT better but the tranny wont shift into O/D unless I let off the gas almost completely, RPMs are about 3 at that time. Am I worrying to much or is this a problem. Thanks again

  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    I'm not sure how your trans. shifts into o/d on that car. Some are centrifugally controlled (weights/governor) and others have temperature sensors that won't allow a shift into o/d until everything is warmed up.

    You might check and see if REDLINE makes a product that can be added to the transmission (NOT a sealer, don't do that) to free things up.

    You know, 156K is really all a transmission was supposed to give you in this life. It has really done its job so anything you get at this point is gravy. You shouldn't feel like this is abnormal or bad luck, it isn't.

    Run it for a while, it might improve!
  • isellhondasisellhondas Member Posts: 20,342
    I would have the fluid changed AGAIN after about 5000 miles.
  • wtd44wtd44 Member Posts: 1,208
    I'd recommend giving some thought to your next car-- the one you'll need to replace this one! Please accept this as the light hearted humor it is intended to be. I wish you nothing but the best fortune with the hurt transmission.
  • toyoman1toyoman1 Member Posts: 52
    Mr Shiftright... is the Redline Product to cleane valves or what is it supposed to do and what exactly is it called ie "cleaner, conditioner, etc..." thanks again for all the input.

    Dealer says my 1987 acura legend torque converter should be replaced. My acura has 140,000 miles. Does it make sense to replace the torque converter without rebuilding the transmission? Dealer says nothing wrong with transmission so why touch it.

    Hi,
    Ok.. Here is my problem. First of all, I am a female, and I do not know alot about cars, so I feel that I am being taken advantage of, and I need someone's help!!!

    In July 2003 my 91 Mazda 323 had the transmission replaced. The warranty was 10,000 km or One year. As soon as I got the car back I noticed that it accelerated weird. The car was taken back in, and I was told that the speed sensor was adjusted. It seemed to drive ok once that was done. The car was not driven at all during the following year because I attended University in another province. I came back in Summer 2003, drove the car approximately 10,000 km (including a trip from Calgary-Guelph 4,000km). The car is now with me in Guelph. The repairs were done in Calgary. I was experiencing the same accelerating problems as before (seemed like the car was slipping out of gear), and this time it sounded Worse. I took the car in, and they told me that it sounded like a transmission problem. They removed the transmission and discovered that the transmission needs to be replaced, but they could not speculate what happened to it. The car is being repair right now, but I am extremely frustrated with the people who initially fixed the car. The Mechanic who has the car right now is speculating that there could have been a flaw in some part of the transmission, but he can not pinpoint it. How is it that the car can need a new transmission already? It has been just over One year!? Even though the warranty says 10,000 KM or One Year, is there any loophole? It just seems ridiculous that I spent 2,000 dollars on a transmission, only to shell out another 2,000 for another one. Does anyone have any advice? Do I have a claim against the original mechanic? I know that the warranty is One year or 10,000 KM. But I took the car in BEFORE the year was up because I was experiencing problems.. I am just at a loss for words.
    Any help or advice would be greatly appreciated,
  • jrichman1jrichman1 Member Posts: 18
    forgot i posted about that. thanks. No i did not get that problem with the tranny fixed yet. NO time with all the new bussiness I'm getting. I think it might be something with shotty wiring , like some one already said on here. Might be that cd player my friend installed for me, he is a "back yard" car audio specialist. LOL

    oh yah, what about if im driving on the interstate, what gear?
  • wtd44wtd44 Member Posts: 1,208
    If you are a college student and currently enrolled, you might want to see if your college has a legal service to help students. If so, you should go there and get started on sorting out what sounds like an unsatisfactory transmission replacement/rebuild. Many colleges and universities are offering legal help to students here in the U.S. Maybe in Canada as well, eh? (:o]

    Thank you for your advice,

  • gregtranggregtrang Member Posts: 11
    Can anyone give me advice on which transmission service is better, a full flush and fluid change or just drop the pan and change the screen and replace the lost fluids that came out? I seems like the flush would be better because all the fluid would be changed out but my mechanic advises against it. Any thoughts?
  • yurakmyurakm Member Posts: 1,345
    To my understanding, the best for transmission is dropping the pan, replace filter, and flush the remaining fluids.

    My dealer suggested flush at 30k miles. The car manual says - transmission service at 50k miles for severe conditions, after 100k for normal. The dealer told me that there is no need in dropping the pan, even while I would prefer to replace filter. When flushing, mechanic found that the old fluid is dirty - and dropped the pan. Flush costs only $89; the full transmission service, including changing filter in addition to flush, costs about twice more.

    My 2000 4wd Jimmy just started jumping out of gear when the vehicle enters into a slight coast or deceleration. The sound it makes is a high speed gear whine and slight vibration in the cab. If I accelerate it will stop immediately but if I let the vehicle coast it will last for up to 15 seconds before it reengages. The frequency of occurance is intermittent. Over the last 3 days it has become a real problem though. The transmission is strong otherwise. Any helpful suggestions would be appreciated.
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    I presume this is an automatic and that it only happens in top (overdrive) gear?
  • rktrkt Member Posts: 5
    Yes, that is correct. I have not tried the duplicate the problem when in drive (3).
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    Well you might try that and get back to us! Every bit of diagnostic info helps.
  • rktrkt Member Posts: 5
    I just drove the vehicle for 20 miles in OD and could not get it to act up. As mentioned above the problem does not have consistency and will not preform on command. I have not been able to ID any condition that makes it start (ie warm oil, etc.) only once it has started that it happens upon deceleration.
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    These intermittent problems are tough. You basically need a constant or very frequent failure for a mechanic to do anything about it.

     

    You might check and see if your particular car has a temperature switch that controls dropping into overdrive...on some cars you can't do that while the engine is below a certain temperature.
  • electricdesignelectricdesign Member Posts: 681
    [Mazda Lover]Transmissions are very complicated equipment, but I shall try to help as simply as possible. First, let's clarify the terminology used. First you said the transmission was "replaced", but replaced with what? I doubt they put in a "brand new" transmission, most likely a "Rebuilt" or "Remanufactured" transmission. "Rebuilt" is like "repaired", they just put as few parts as possible to get it working again, they will reuse "questionable" parts, therefore the "Rebuit" is not as good as the "Remanufactured" transmission. The "Remanufactured" transmission has All New Parts inside, and is often better and more expensive than a "New" transmission, when done by a professional remanufacturer. The 10,000 km warranty is a little short, so it seems to imply that they did not put much faith in their work. I would expect at least a 12,000 mile/1 Year warrenty. When they pull a transmission out to inspect it and tell you it needs to be replaced, they need to tell you EXACTLY why, and what parts failed, and why they failed, even if you don't understand it, and get it All in writing. That way you can show it or explain it to someone else that may be able to help you. I have seen many transmissions fail in less than a year due to sloppy or incompletent work. If they do not put in a new set of Thrust Washers, the ones they reuse can start to deteriorate and release metal particles into the fluid that causes wear and damage thoughout the entire transmission. If they do not completely clean and flush the transmission fluid cooler, it can release metal particles back into the fluid that causes wear and damage thoughout the entire transmission. If they reuse the existing torque converter, it will release metal particles back into the fluid and cause wear and damage thoughout the entire transmission.

    The secret to making an automatic transmission last a long time is to keep it COOL and CLEAN!

    I can't do much about your present problem, other than suggest you try the legal route, but try to remember this post in the future. This may help you and others in the future avoid a lot of problems.

     

    [gregtrange] The best way to service an automatic transmission is to FLUSH the old fluid

    from the transmission, AND pull the pan, replace the filter with a new one, clean and replace the pan, fill with new fluid.

    Flushing the transmission without pulling the pan and changing the filter is just about useless.

    Pulling the pan and changing the filter without flushing the old fluid out is just about as useless.

    I flush mine myself, 2 cases of ATF=$48, Filter & gasket=$12. It cost me about $60 and 2 hours of my time.

     

    Hope this helps,

    Good Luck,

    E.D.
