Default Shifter not shifting

In the process of removing the transmission it got knocked out of park and locked the shifter up and now won't turn on, when you turn it to aux and shift it from under it'll show its in reverse neutral and drive but won't show its in park

IF it has a shift Sensor mounted on the shifter side of the transmission, did it get damaged? Maybe it isn't aligned properly? I had a Shift Sensor replaced and messing with the shift cable can mess things up if not properly aligned. But, I'm thinking if this was the case, you should get an error code. I replaced my Shift Sensor and now things are great.

The question you responded to was from a more than ONE YEAR OLD Thread?
