What It Helps Address

Installation Notes and Tips

Install during a transmission service when the pan is removed and the fluid is being replaced. Verify the vehicle application by year, make, and model before ordering, since fitment varies across Cadillac, Buick, and Oldsmobile platforms. For best results, inspect the pan, gasket surface, and fluid condition at the same time and follow the vehicle manufacturer’s service procedure.
