Car doesn’t move while in gear !! HELP

[Fiilthyy]

I had made a thread before of having the U0100 code and being stuck in park and no crank no start. The little white lever in the trans wasn’t in place.. I had also broke a pin where the TCM harness connects and I soldered it to extend it and I’m getting voltage (I know I rigged it but it works for now meanwhile I find another one).

The car now starts and goes into gear but doesn’t move at all… I got the transmission checked out and it’s not blown or anything. Brand new torque converter because the other one took a crap. What could be my issue now? No codes pop up.

There’s no grinding at all when I throw it in gear, all it does is the left rear wheel moves just a little bit but only if the car is jacked up from the rear.. I checked and the driveshaft doesn’t move , I had thought maybe my diff also took a crap or my axles but they’re good. Any thoughts?
