I have a 95 F-250 4x4 with the E-4OD transmission. The truck has 184k miles on it, but I bought it with 159k, so cannot be sure what prior work was done, if any.

Just today, I noticed transmission was slipping when going into 2nd. With mild acceleration, it is not noticeable at all but does present when I accelerate a little harder.

The first shop I consulted today checked with his computer and determined it was not throwing any codes. He returned from his test drive saying it had a problem with 2nd gear and the trans needed to be rebuilt. Quoted $1800 for the rebuild and either $500 or $800 for the converter. He claimed the $800 was better for towing and would also yield better mileage. This shop is one of the most respected in area.

The next shop, also well thought of, just test drove it and returned saying it was a case of old age. There was accelerated wear, but he wouldn't say it had to be rebuilt. If I wanted it rebuilt, he quoted $1200-$2200, including the converter, which he claims are custom built to the job by a local individual.

I don't want to drive it until it self destructs.

I don't want to pay for a rebuild if a specific repair would fix it.

And most important, I don't want it to puke in the deer woods.

Suggestions, please.

 

The normal life span for an E4OD is way less than 184k. 75-175k is considered normal, except for turbodiesels, which eat those transmissions for lunch. My rebuild cost $1400 plus tax and installation, $1800 total installed in a 4x4. That included a shift kit, new converter and external cooler.

I have the exact same problem with my '97. Oddly, it is also somewhat temperature dependent... only slips after the tranny is up to operating temp.

With no repair ideas submitted to my post here a few weeks ago, I figure it's just old-age and I'll drive it until it won't go- then rebuild it.

If you find a non-rebuild solution to the problem, I sure would appreciate it if you post the info here on the board.

 

Same problem here. '92 F150-E4OD. Slipping will only get worse, and start affecting other gears. Just checked my trans pressures, all running low. From all that I have read here and elsewhere, a worn pump and a worn bushing are causing my problems. Got 211K out of mine before it went. Anybody out there have interchangeability (?) data between different year models. Willing to make mods. Thanks.

 

slipping is usually caused by low pressures, and those can be generated by wear at pump, busings or even burned seals.

In electronic controlled trannys, problems related to engine sensors can also produce erratic response from engine and/or tranny wich can produce also slipage.

In my experience the best is dissasembly tranny and perform a full diagnostic on all internall parts. After reapir, pressures should return to normal, if this doesn't happend there is a problem external to tranny wich is causing low pressures and slipage.
