I just had my 1990 F350 dually towed 250 miles due to the trans going out. The trans initially started slipping from a standing start and then it lost all the forward gears. The trans has been regularly serviced. I have read that the E4OD was upgraded throughout the years and since it looks like I'll be rebuilding it, I would like to upgrade it where I can. I picked up a donor E40D from a wrecking yard out of a 1997 E350 van.
Should I rebuild the trans from the E350 or should I take the parts from it and put it into my original trans? I know the trans solenoid was changed around 1995. Am I correcting in thinking that I'll have to use the 1990 type solenoid in what ever trans that I use? I don't know what unforeseen issues that might come up with my intended rebuild.
Specs:
1990 F350 Crew Cab Dually, 150K miles
7.5 Gas engine, E4OD trans
Used to tow race cars
Donor Trans: 1997 E350, 7.5 Gas
Thanks for the help.
