Installation Notes and Tips

Verify transmission pan shape, mounting hole count, and drain plug location against the original part before installation. Clean the transmission case sealing surface thoroughly and inspect the mating surface for damage or debris. Because gasket or seal is not included, use the correct service gasket specified for the vehicle and transmission. Confirm fluid level after installation and follow the manufacturer service procedure for the specific Silverado or Sierra application.
