Installation Notes

Verify transmission type and pan style before ordering, especially on 1981 Chevrolet Bel Air and 1981 Pontiac Laurentian, which note THM200-4R and 4-speed applications. Confirm the vehicle match against the fitment list and inspect the pan sealing surface during service. Replace the filter and gasket during a transmission fluid service to help maintain clean fluid circulation.

Quality Assurance

ATP Parts positions this Premium Replacement line as a service-focused option for maintaining transmission cleanliness and reducing the risk of debris-related internal wear. Regular filter replacement helps protect the valve body and other vital transmission components from clogging.
