|Depending on the version of this trany you may have electronic problems or serious internal failure. Either way most backyarders can't diagnose or repair this problem. As I don't work on much light duty I would borrow my freinds scan tool and do a electronic scan on the trans switches and sensors. Then, if its a mechanical failure, drop the trans out and drag it into the repair shop. Good luck|
