I have a 2003 Chrysler Town and Country and my problem started with no reverse after starting car. If I pushed it back and drove forward 10 or 15 feet then reverse would work fine and shift properly. As long as I could drive forward first then reverse would work. This was like this for a few days then the vehicle wouldn't move at all. There wasn't any error codes. The fluid is full and clean.
When the van was about a year old I took it to the dealer with harsh shifting and they said there was a broken wire to the trans, I am thinking this is when they came out with the 3 wire slice people where talking about.
I wasn't needing the van so it has been sitting now for almost a year. Now I want to get it working again and I would appreciate any suggestions.
Thank you
