I got my rebuilt tranny (th350) in to the car and got every thing hooked back up, Filled her with tranny fluid. Started the car up and she ran fine. Took it out for a road test, jus a few blocks, long blocks, got back home, checked for leaks found none, checked fluid level again and it was fine So now I cant get my key out of the ignition switch, its seems as if the ignition wont rotate all the way back to the lock position to allow removal of the key. Whats up with that? Its a coloum shifted th350 in a 72' monte...Help!!!
