I have a 1994 F150 4x4 Auto E40D with a 351W. I recently installed a new engine and torque converter last year and rebuilt the transmission the year before. My problems started back 2 1/2 years ago when my transmission started having trouble staying in overdrive. The problem was pretty rare and when my father offered to pay (and allow me to pay him back) to have it rebuilt I took the offer. Following the rebuild the problem intensified. It started to shift extremely hard into gears, never shift out of 1st, or after it shift out of 1st it would shift immediately into 3rd. Of course I took it back to the repair shop instantly. After two more weeks they claimed they couldn't find the problem even after replacing the TPS sensor, a speed sensor in the rear axle, and scanning the computer for error codes nearly 15 times (or so they claim!) To cut a long story short, even after transmission flushes, filter changes, a new torque converter the problem still persists. It remains very very random. Some days it operates without a hiccup and others you can't get out of the driveway without cursing it! The truck is a second vehicle and due to money restrains this problem remains unsolved. The more I read up on common problems with this transmission I'm led to believe the original shop incorrectly rebuilt it or perhaps it is a computer issue. A current option I plan to explore is adjusting the steering column shifter and the shift linkage on the transmission (this process is in my Haynes repair manual I just can't recall the exact name of the components). I am also concerned with perhaps the shift interlock? I am very unfamiliar with this feature of the drive train and the thought occurred to me after the engine stalled after the transmission shifted up . Has anyone ever heard of such an illusive tranny ghost problem or is the real part to blame in front of me this entire time?

Hi all, My 1990 ford f350 transmission is acting up. First let me give some history. The truck is only used 15-20 time a year. Has slipping problem about 15 months ago. Had trans rebuilt. After about 1 year seemed to be having problems when shifting mainly from 2nd to 3rd took back to trans shop. They said mid shift bearing and rear axel bearings were bad. Had repairs done. Used truck locally several times and shifted great. Went on longer trip and noticed some delay when shifting from 2nd – 3rd. took back and they replaced trans vacuum (cant remember name of part) on engine with vacuum hose going to trans. Still shifting problem 2nd – 3rd also noise when down shifting. Ford test drove and said seemed ok. (at this time I had not realized it was not happening until truck got warmed up) Realized on last trip that it does not start until truck is run for an hour or so. Shifts great when cool but after warms up there is sort of a delay when shifting from 2nd – 3rd. (when it shifts you get bounced back in seat, kind of like delay in shifting. Makes noise when downshifting ) I am afraid to go back to original trans shop after 2-3 visits they have only replaced more parts Thanks Jim

| Pulled a 5 speed from a 1994 ford which shifted well and was real smooth. Then I put it in a 1992 Ford f150. Right after I put it all in the truck I found it was in gear. Now I can't get it out of gear. The clutch slave seems to be doing its job, and I bled the system, and have done all I know to do. Any suggestions on what it could be?? | |

I have a 1997 Ford F350 dump truck that is having some transmission problems - it's an automatic. I purchased the truck in September 07 with 95,000 miles. Before winter I had the transmission flushed. I use the truck for hauling and snow plowing. While plowing, I began having trouble with the truck not shifting out of 1st gear after it got hot - I was going up a hill after having plowed for the past 2 hrs. I could manually shift it into second and shifting into reverse was not a problem. It seemed to be low on fluid so I added a quart. It is possible that I added too much. It was dark out and I was in the middle of plowing when I added the fluid so there is a possibility that I added too much. The fluid was dark and smelled burnt even though it was flushed just a few months ago. This makes me think that perhaps the trans oil cooler is not working or has a leak. Just last week it began giving me trouble when I put it in reverse. I have to push the accelerator to the floor before it finally moves. The two mechanics that I have brought the truck to have suggested replacing the transmission or rebuilding. One other mechanic said that it might be the speed sensor. I'd like to hope that it is something a little less expensive than a rebuild or new tranny. Do you have an thoughts or suggestions? Thanks. Thurman Wilder Montpelier, VT

Replying to: thurman54 (Mar 27, 2008 12:19 pm) If you are plowing and have a Dump bed on it and it's never been replaced or rebuilt I am shocked the Transmission has lasted that long. I put a post last week about where to go for Ford Diesel Parts and even a Guy here in Denver, Colorado about having our Trannys rebuilt, the shipping cost for you to ship yours here and get one back might cost a little more than the 300.00 total round since you live way up in Vermont, lol. Damn dude I just Mapquest Montpilier Vt. and you are not near any place of Size, you don't seem to far from Burlington though, the only reason I know that place is that my wife used to fly in there for US Airways when she was working out Indiana, lol. If you are near any race tracks in your area you might want to contact them and find you a good Transmission guy there. I have not called Dwayne in a while but I can double check on what it would cost to ship one out. Just the Tranny & New Torgue Converter is around 2250.00 but it is a very well built Tranny. With the Shipping you are probably looking around 2500 to 2700 depending on what kind of deal he or maybe even you could get. Might have to Ship and pick it up out of Burlington. Let me know if you want me ask him or if you want to check around you. The reason I said Race tracks is that usually they have people that rebuild Trannys and that for the same price as dealers but build them to actually last. Tony |
