Fresh Rebuilt 904 locked up

Try disconnecting the cable, and work the trans lever by hand...
That's what the shop will probably have to do tomorrow to push inside. I'm wondering about what will be when it gets reconnected. When the car was towed home from trans rebuilding shop I was told there was an issue with the park lock cable and it had to be ( I think ) rotated about 90 degrees for fit and was leaking a little ATF. Yep, that from the shop that rebuilt it. I've always had manuals so don't know jack about autos.
