    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.

    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.
