It is a well known problem I learned the hard way. To make it quick and easy disconnect the electrical line to the transmission. You need your automatic clutch rebuilt around $350. It's fine disconnected electrical line for town use long trips rebuilding is necessary.


I will that a go tried everything else .With that disconnnected will it give any codes or is there a way to complete the cicuit

Probably not. You can always go the repair route for around $350 I am a poor boy from the ghetto and have been running my car with the transmission disconnected for 3 years. It is a well know fix just ask any old school mechanic and he should know my mechanic is old school and I trust him. I put a ton of money into trying to fix the stalling and engine stops for no reason problem trust me on this one.
