Transmission codes on 1999 Chrysler 300M after engine

Customer Question

Transmission codes on 1999 Chrysler 300M after engine replacement.
Recently replaced the engine and after everything was outback together the car will not move. I can move the shift lever and it acts like it is in gear but will not go forward or backwards. Codes P1782, P1784, and P0700 are showing.
Any ideas what maybe causing this?

I am sorry that you have not been helped yet. I just came online and saw your question.

Did you ohm out the wiring or just physically check them and if so, did you trace the wiring all the way between the transmission and tcm?

Also, if I can get the last 8 of the vin I can pull any needed schematics for testing
