most likely either a valve body issue or an internal failure. It is a gear ratio code. The sensors and tcm have no bearing on the code. It is an internal slippage that sets the code and puts it in limp mode

I had same issue with my 05 neon was not an internal failure, it was a broken wire to the output speed sensor. Repaired wire cleared codes, 20 mile test drive. Problem solved
