Why This Filter Kit Matters

Transmission fluid carries wear debris over time, and a clogged filter can restrict flow to the valve body and other internal components. Replacing the filter during service helps keep fluid passages cleaner and supports proper transmission operation. ATP B-54 is a practical choice for owners maintaining classic Buick Regal, Chevrolet Caprice, and Pontiac Grand Prix models, as well as other listed vehicles from 1979-1987.

Installation Notes

Confirm the transmission uses a 2-9/16" deep oil pan and verify the transmission family before ordering, especially on applications with TH200, THM200, THM200/M29, THM200C/MV9, or THM250C/M31 notes. Clean the pan and mating surfaces thoroughly during service, and inspect the fluid for debris that may indicate internal wear. This part number, B-54, is commonly searched for classic GM transmission filter service on Buick Regal, Chevrolet Caprice, and Pontiac Grand Prix applications.
