Everytime I talk to friends who work in the industry, they say that there are considerable problems that can result installing transmissions from different models into the Mark VIII. Even if you swap the MLPS, TCC, the speedometer gear, and the wire hraness, I'm told that it still won't be quite right. They mention computer problems, gear ratio differences, and just general things.
Is this the case? Do the internals work perfectly in all the 4R70W cars? And if that is the case, how can I it be explained?
