    The TH400 went out in a 3/4 ton suburban, 4x4.
    We have a 2wd suburban, same year, with a TH400.
    Can we swap the 2wd TH400 into the 4wd one?
    What does it take besides putting the adapter on?
    Shafts?

    I'm quite certain the TH400 2wd output shaft (bolt-on yoke type) is the same length as one of the 4wd shafts... I know its not the NP203 version... must be for the 208 or 205. :thinking:

    I believe that this has a 241.
    Not positive.

    2WD 400 is different than 4WD 400 unless it has the bolt on fixed yoke at the tranny.
