One thing worth checking is whether or not your clamshell is bent from the original incident. If you take it off the car and lay it flat on your garage floor, you should be able to c9nfirm that. If it is bent, well, bend it back (within limits).
It would also be worth running thru the steps in the video below to confirm that everything is correctly aligned internal to the transmissions.

These may both be things you’ve considered, but figured at least worth teeing up.
