Moparts,

I have searched on this issue on google and wanted to get your take. Two weeks ago my wife is driving down the road and then hears a clunk and then the car would not shift out of 2nd all the way home. The car also began to run warm. Today it happened again a clunk and then the car would not shift out of 2nd again. Last time I put a tester on the computer and cleared the code and it worked fine. (PO441)

Since then Ive been geting a P0700 code and a PO871 with hard down shifts into 2nd while breaking or decelerating it wants to stay in 2nd until it is turned off.

It seems to be some type of sensor that is the issue from my research.

PO871 - Overdrive Hydraulic Pressure Switch Circuit

Hoping someone here would have some additional insight for me on this error. It seems from the error that some have replace the valvebody on the transmission and this has solved the problem. Others it was the output speed sensor on the tranny or the battery or alternator. Others says loose wiring, any advice would be amazing!
