E40D Transmission Issues
Hey guys, first post, and need some help.
1993 F250 Diesel, IDI with the E40D. Has about 275,000, 4 wheel drive.
The problem is the transmission keeps putting itself into a "limp mode". Codes pulled point to the TPS / VSS, which has been replaced and adjusted with no improvement. If I unplug the battery terminals, it shifts great. It does not slip, nor does it shift hard. About 10 minutes later, or a couple of miles, it will go into this limp mode. Resetting the computer (unplugging the battery) always resets the code, and always allows the truck to shift well.
I haven't had my truck for about 2 months, and getting very upset and bothered by the "experts" at this transmission shop. I think they have been pulling my chain / taking advantage of my situation. They now say the transmission needs a rebuild or clutch packs because they found shavings of metal in the valve body. I do not believe them, nor do I see how this will solve the issue of a TPS fault. I'm fairly sure that I have read every thread that has the keywords "e40d" and "problems" but no solutions that have worked. Here is what I have done / transmission shop has done.
Replaced VSS sensor
Replaced PSOM (several times)
Replaced ABS moudle (several times)
Replaced Cruise Control Servo (cruise control still doesn't work, if that drops any hints)
I then then took it to an aamco dealer..
They said they traced it back to a PCM for the transmission..
Replaced PCM Transmission - 500+ Bucks
Checked all grounds (this is what they said)
They have claimed to have "fixed the problem" several times only to go pick it up and have the code reappear 5 minutes from making it home. This has happened at least 5 times for the last two months.
Recently divorced, going through a tough time financially, can't really afford to be paying idiots for the best guesses. I really need my truck.
