I have a brand new TKO- 600 that I installed on my stang. After I finally put it together I went to crank and its locked. The whole drivetrain is locked. I tried turning it at the crank and nothing. I took the tranny out, and tried turning it at the crank and it turns, no lock up. It seems the problems is at the tranny. Anyone else experience this? It is the only thing holding me back from starting it.
