Installation Notes and Tips

Verify the transmission filter style, thread specification, and OE number before installation. This filter uses a spin-on design with an integral gasket, so the sealing surface should be clean and free of old gasket material. Confirm fitment against the vehicle’s transmission service requirements, especially on 2001-2019 Chevrolet Silverado and GMC Sierra heavy-duty applications.
