Detailed Description

PT239 is a Premium Guard transmission filter kit covering a large range of older rear-wheel-drive passenger cars, wagons, and trucks. Fitment includes Buick Regal, Chevrolet Caprice, Pontiac Grand Prix, Oldsmobile Cutlass Supreme, and many other GM platforms from 1970 through 1985. Use PT239 when servicing the transmission filter on applications listed in the fitment table, including models such as the Chevrolet Camaro, Buick LeSabre, and Pontiac Firebird.

This part cross-references Gates T239 and T113 for the same application. The PT239 part number is also used across multiple interchange listings, which helps confirm catalog matching during transmission service.

What It Is Used For

  • Replacing a clogged or restricted transmission filter
  • Restoring proper fluid flow through the transmission service system
  • Addressing service needs during transmission maintenance
  • Supporting repair on older GM automatic transmission applications
  • Matching the correct filter kit during parts lookup by PT239

Installation Notes and Tips

Verify the vehicle year, make, model, and any fitment notes before ordering. Body style notes such as sedan or irregular-shaped application details matter on some listings, so match the catalog entry exactly. Confirm the transmission service application against the vehicle record and compare the existing filter to the part number PT239 before installation.

Quality Assurance

Premium Guard PT239 is cataloged with extensive interchange coverage, including Gates T239 and T113, which supports accurate parts matching for service work.
