Whether you shift for yourself or not, this will be the place to diwscuss tranny questions.

  • i need help with 95 f-150 manual tranny. tranny shifted fine going to work but when i left work and shifted into reverse had to really rev up the engine to get truck to move and the same was true with the forward gears. the truck finally quit pulling totally.

    How's your Clutch? Sounds like it's slipping and is either badly in need of adjustment or needs to be rebuilt.
  • I have a 2005 F150 supercrew, 4.6L, automatic. 2 wheel drive with 45,000 miles. I just noticed a grinding noise coming from the transmission or differential when I start out from a stop. The noise seems to be in the lower gears only and returns when I slow down to a stop. Any ideas?

  • I have a 93 F-250 4x4 Automatic. When you shift it to Drive it will go threw the gears till it gets to the overdrive, then it just acts like you shifted into neutral, if I push the button on the gear shift knob to turn the overdrive off it will go into gear then, as soon as you try the overdrive it will not go until it slows down to the lower gears. Once in awhile I can get it to work if I drive it for 15 or twenty minutes in drive , also the gas gauge won't work on the front tank when this happens.
  • Can anyone help with an answer. After a twenty minute highway drive, when slowing for off ramp the transmission makes a grinding sound and just before stopping it clunks down into first gear. I have had it back to the dealer and they have not been able to repair it because they cannot get the truck to repeat the noise. Does anyone have any sugestions as to what might be causing the problem.

    Hi, anyone know about this: 1991 f150 xlt lariat 2wd 302, when driving about 40 mph tranny slips, have to shift to L2, tried changing fluid that help in that now the tranny slips about 55 mph.....any ideas?
  • KCRamKCRam Mt. Arlington NJPosts: 3,516
    You need to do more than just change the fluid - especially if it was done via the tube and not by dropping the pan. My 90 and 96 F150s (both 302 and AOD 4-speed automatic) were very cranky without a full transmissionservice - fluid, filter, band adjustment, pan gasket. If your truck didn't have an auxiliary transmission cooler, you may want to invest in one, as these trannies overheat.

  • Just wondering if you are having the same problem as I am having, with the OD, one guy tells me there is a elec. switch on the tranny that has to engage the OD, when I went to the Ford Parts store they said there is no such thing on the E4OD trans. but the other mecanic I talked to said he has replace a couple of them, and he bought the switch at the Ford store for about 47 bucks, anyone know what is what on this deal. :lemon:

    See my entry #4 above. I had the same problem with my 2005. took it to dealer and they said the gear set was shot and advised me not to drive it off the lot until they checked it out the next day!! They ended up installing a whole new transmission for $1400, after Ford discounted it from $3000 since the truck was only 9,000 miles ot of warranty. Since the 2006's have that 100,000 mile warranty on the drive train, sounds like they are balking on replacing the transmission early instead of later.

    (That should've been 90 and 93 F1450s I used to have, not 96).

    The E4OD did have an OD switch on the shifter tip. The AOD selections went P-R-N-OD-D-1, the E4OD was P-R-N-D-2-1 and the tip switch controlled OD off/on.

  • This 93 has the OD switch on the shifter, I looked at the trannny and notice there is a sticking indicating that it is a remanufactered tranny, no date, there is a wiring harness connected to the shifted at the tranny with several wires, I suppose for bacup lite and saftey start, but is there also a OD wire in that harness???
  • Gary,
    Just had my 2002, F150 with 60000 miles lose the "Sun Gear" (weld broke) this in turn destroyed the clutches, Torque converter, and Overdrive. All total a bill for $2,100 for a new Transmission. Not sure if this is a common problem with this Trans, Just trying to get some feed back before I write a letter to Ford about it. Any help would be grateful

    91 F-150 5.0 L with the larger OD tranny. Dec 05 had tran rebuilt. Last week started shifting rough. Took back to shop. Mech installed a new solenoid pack in tran. Yesterday drove 20 miles home no problem till I turned last corner onto my road. BAM!, it started again. Mech said smietimes electrical issues can cause rhe part to malfunction. Could I have some sort of wiring problem elsewhere that would cause this.
  • I have been going threw all the elec. plug in on my 93, it seems to work part time but still takes about 10 min. to start shifting into D and OD. I have been cleaning and adding the elec. grease. I am wondering if maybe the TPS may have something to do with it, I'm going to change mine and see if it helps.
  • my 2006 f150 has had a vibration during acceleration.i have had it back to the dealer 3 times.They said it is normal.I find it hard to believe they would invest in quiet steel and not worry about vibrations.It is like a buzzing more than a grinding.It is not acceptable to me that the 2 vehicle's i just sold,a honda with 150,000miles and nissan pickup with 85,000 miles were smoother than my brand new truck.And the dealers response to this problem was IT IS WHAT IT IS.It is the last ford and american vehicle i will ever own!Good job FORD another lost customer.

    Don't take one dealer's word for it. If you are unhappy, try a different dealer.

    I've had my F-150 (4X2) for a while with 120K miles. I mainted it pretty well with all the scheduled maintenance. But, I found out a few months ago that the radiator fluid was flooded with pink transmission fluid. My machanic said his never seen it before. I replaced the radiator and flushed both the radiator and transmission (this took more than 6 tries at the dealer over a 3 day period). They warned that there might be transmission damange and told me to keep an eye on it. This seemed to have fixed it for couple of months.

    Now I find that the transmission is very rough and it hesitates for upto 5 seconds from 1st to 2nd, which makes the truck loose power dramatically. I'm afraid to take it in to hear that the transmission needs to be replaced. Everything else seems to be fine. There is no 'funny' noise or feel when the car is idle or is in high gear.

    Does anyone have any ideas of what I might expect to hear and what my options are if I need to replace the transmission? I don't want to take it to a dealer as the labor rate is high, but it's too big to trust it to my local mechanic. Any thoughts would be appreciated.

    First you need to find a different mechanic if the one you have been using has never seen an internal leak in the radiator between the cooling system and the transmission cooler. Granted this is not a very common problem but certainly not unheard of either.

    My preference would be to ask friends,co-worker, etc for a recommendation for a independent shop that specializes in transmissions. It sounds as if your transmission is on its last legs.

    transmission does not engage right away when engine cold.everything find when warmed up.fluid ok.any ideas

  • Hope you have better luck the me, I have had my 250 in the tranny shope for going on 2wks, they have had it hooked to the computer, but says my truck won't talk to their computer, the took it down the road to an elec. specialist and got the same thing. Now they are going to try going wire by wire. Mine won't go into D or OD till it worms up but will go in 1 and 2 .

    Thanks for the information timbertim please let me know how you make out.My truck is presently in the body shop;so I have to wait before repairing the tranmission.
    thanks again
  • Just got my 93 out of the shop. It was the Solenoid in the transmission and the wiring harness that conects to it. Replaced both after 2 weeks of checking things out. Tim
  • dec.03/06

    Thank you very much for the information Tim,this will be helpful for me now and in the future.

    Had the same thing with my 2004 FX-4. Finally nailed it. The geniuses (geni?) at Ford made the IWE solenoid notso much weatherproof, and it controls the 4wd system. There is a TSB out for it finally. TSB 06-08-145. Now I'm trying to get them to do something about my tires......
  • help!
    I have a 2001 f-150 xlt 5.4 auto standcab l/b 4x4.Im the 2nd owner and got it with 39,000 mi.It has clunked when shifting from 3 to 2 and does it mostly when there is some let up on the accel like turning and then accel causing the tran to dwn shft.clunk.Its not noticeable from a stop but have had it happen with atv trlr on the back in stop n go traf. I have ext. warrt and so far dealer has tried lubric. of drivshaft yoke and this week pulled tranny, replaced clutchpack, torqconvtr,any items possible suspt. It seems worse and am going back 12-28 to diagnos further. It does this in 4wdr as well.Any ideas? On my 2nd dealership.
  • I have a 1996 F250 4x4 with an E4OD transmission. Recently, the speedometer stopped working and the OD light started to blink. According to posts that a found at several Ford forums, this usually occurs when the ABS speed sensor fails. Even though the ABS light didn't come on, I replaced the ABS speed sensor (located on the differential). This hasn't fixed the problem. Does anyone have any idea what may be causing this problem? The transmission was recently rebuilt (less than 11k miles) and the torque converter was replaced at that time. I have checked all the fuses (all ok), and scanning with an OBD II scanner has not turned up any codes. Any help would be greatly appreciated.
  • Looking at buying a 1989 F250 4x4 - 302 AOD. Tranny seems to work fine, but has a slight whine that starts in 3rd gear, but almost entirely disappears in 4th. Were these transmissions known for any kind of whine, and is there anything else I should look for???
  • I'm having the exact same problem with my 2006 F-150 and can't get it to happen for the dealer when I take it in for service. I have tried driving it differently to see if I can make it repeat without success. However, I am noticing that the frequency of occurrence is increasing. The problem is strange especially since the truck has less than 17,000 miles. If I get any results with my dealer I'll post back.
