ATP Parts B-53 Transmission Filter Kit

Transmission Filter Kit for THM325 Service

ATP Parts B-53 is a Premium Replacement transmission filter kit built to keep automatic transmission fluid clean and protect critical internal components from wear debris. Clean fluid helps maintain proper flow through the valve body and related passages, which is important for consistent transmission operation.

This transmission filter kit is a direct-fit service part for select Buick, Cadillac, and Oldsmobile applications, including Buick Riviera, Cadillac Eldorado, Cadillac Seville, and Oldsmobile Toronado models with THM325/M32 coverage where noted.

Key Features

• Transmission filter kit for automatic transmission service
• Premium Replacement line from ATP Parts
• Helps remove debris created by normal transmission wear
• Supports cleaner fluid circulation through the valve body
• Part number B-53 for catalog and cross-reference use
• Compatible with select 1979-1981 Buick Riviera, Cadillac Eldorado, Cadillac Seville, and Oldsmobile Toronado applications

Detailed Description

ATP Parts B-53 is designed for routine transmission maintenance on vehicles that use the THM325/M32 platform, including 1979-1981 Buick Riviera, 1980-1981 Cadillac Eldorado, 1980-1981 Cadillac Seville, 1979-1981 Oldsmobile Toronado, and 1979 Cadillac Eldorado with THM325/M32 notes. Replacing a clogged filter helps keep transmission fluid moving cleanly through the system, reducing the chance that debris will restrict the valve body or other vital passages. This part cross-references Gates 18112 for the same application.

What It Helps Address

• Restricted transmission fluid flow caused by debris buildup
• Contamination that can affect valve body operation
• Service intervals where the existing filter is no longer clean
• Transmission performance concerns tied to dirty fluid circulation
• Wear-related maintenance on THM325/M32-equipped vehicles

Installation Notes and Tips

Verify transmission identification before ordering, especially on 1979 Cadillac Eldorado applications that require THM325/M32 fitment. Match the vehicle year, make, model, and transmission type to the catalog listing before installation. Use standard transmission service procedures and inspect the pan and fluid condition during filter replacement.
