These transmissions have problems with the valve bodies wearing out internally. If the valve body was replaced in your transmission when it was rebuilt, I suggest bringing it back to that technician to have it inspected under warranty. If the valve body was not replaced, then I would have a qualified independent technician, such as one from YourMechanic, verify the diagnosis.

Hi there. Check the wiring from the starter to the ignition switch. There is a loose wire or a break in the wiring that connects the starter solenoid to the starter relay. Make sure that all of the wires on...
