Preparation and Safety
Ensure the vehicle is parked on a flat surface and the parking brake is engaged. Disconnect the negative battery terminal to prevent electrical issues. Drain the transmission fluid and remove the transmission from the vehicle following the factory manual’s safety procedures.
Disassembly Process
