Totally frustrated right now...New TKO won't mount up after 3 hour battle.

I am afraid to break the casting. I applied a good amount of torque then stopped. I am going to take some more measurements...something is hanging up. BTW, I am using a bearing. The 31 spline dummy input shaft slides in like butter.

Steve,
Do you have an accurate caliper or even better a mike? Try measuring the diameter of the nose shaft of the transmission where it slides into the pilot bearing vs. the diameter of the nose shaft of the lineup tool you're using. Maybe the lineup shaft is worn from use and small enough to just slide in, where as the new input shaft is tighter? Just a guess but it can't take more than a minute to check if you happen to have the tools on hand. Sorry I can't be more helpful.
