I just got a used 700r4 from someone on here, and i cant seem to get my old tc in this tranny? I can tell when its all way in, it is at the point where it looks like it is in but it still has to go one more knoch. Are there different splined tc for 700r4? I spent over a hour trying to get this one in and i cant get it!!! update, ok after looking at the tc there are 3 places where one spline is missing, if that makes sence, so im guess then that my tc is an older one with only 27 splines right?
