Hello everyone, I'm hoping to get some idea here as I am running out of patience with this project.
What I'm dealing with is a powertrain from a 94 F250 IDI factory turbo, E4OD. I've actually got it swapped into a 2009 Dodge, which has been a lot of fun. What is not fun, is getting this transmission to behave. The donor truck had been parked for several years, so I do not know the history on it at all. I rebuilt the engine completely, and it's running great.
Once I got the EEC IV all wired up and fresh fluid in the trans, I took it for a spin. It was a bit iffy at first, slipping in 2nd. The next day I drove it again and 1st/2nd felt good, 3rd was slippy. The next day I drove it everything felt great. I drove it to town a couple times. The next day I drove it to work, and on my way home I couldn't get it over 40-50KPH on the highway (I'm assuming that was 3rd. Any amount of throttle to accelerate and it would slip. I then rebuilt the trans myself. I found the drive clutch and direct clutch to be black and heated, but still lots of friction material left. The only other problem I found was one of the center support bolt/passages was quite loose, I backed it out with my fingers. (I'm aware the torque spec for these is only 10lbs) I also installed a transgo shift kit. (not the tugger). Also put a new MLPS on it.
I took the truck for a good boot the other day, and it felt pretty good. Decent shifts, the only thing I noticed was kickdowns didn't really make it want to downshift. I stopped to visit a friend for an hour, then drove home, and halfway there it started slipping like crazy again at about 100KPH, which I'm assuming was 4th. Today I checked the FIPL and it was 1.2 - 3.8V. I had a new one, so I installed it and set it to 1.4 - 4.1V.
I intend to put a gauge on to watch the line pressure before I drive it again, I really don't want to smoke the new clutches. Oh, and I pulled the codes and all I have are:
22 - Baro out of range
23 - Throttle sensor out of range (this is why I changed and calibrated the sensor)
Anyway, does anyone have any suggestions on what to attack next? I understand the TPS is really critical, and dictates line pressure, but is it possible for it to cause a slip? I have not replaced the solenoid pack, but I'm thinking that might be my next go.
