Hey Guys. New to the forum. Just purchased an 02 Neon SXT Auto. Having some issues with the transmission.. Stuck in gear. I'm receiving a fault on shift solenoid A. My first approach was a transmission flush and filter change. Did that and didn't fix the issue. Second was replace the shift solenoid . No go. Third was replace the TCM and check all the ground wires. Still the same fault.
I went as far as replacing the transmission itself. Still with the same fault.
I really don't know what else to do at this point. Please help
