Detailed Product Information

The transmission oil pan is a critical hard part that holds transmission fluid, which is essential for lubrication and operation. When a pan is bent, corroded, or damaged by road debris, fluid can escape and lead to transmission wear or failure. ATP Parts 103012 is made to fit and function like the original pan, supporting a proper seal and dependable service life. This part number 103012 is a direct-fit replacement for applications such as 1984-1993 Buick Century, 1983-1993 Oldsmobile Cutlass Ciera, and 1988-1992 Pontiac Grand Prix.

This part cross-references OE numbers 265808 and 8662942 for the same application.

What It Helps Fix

Transmission fluid leaks from a damaged or corroded pan
Fluid loss caused by a bent sealing surface
Leakage from over-tightened drain plug or pan bolts
Service issues related to an aging OE transmission pan
Replacement needs on GM cars such as Buick Regal and Oldsmobile Cutlass Supreme

Installation Notes and Tips

Inspect the pan rail, drain plug area, and sealing surface before installation. Clean the mating surface thoroughly and verify the gasket surface is flat so the new pan can seal correctly. Confirm vehicle application by year, make, and model before ordering, including 1986-1990 Cadillac Eldorado, 1986-1991 Buick LeSabre, and 1990-1992 Chevrolet Lumina.
