Detailed Product Overview

The W39341TC is a transmission oil pan gasket for vehicles that require a cork gasket with a metal carrier. This design helps maintain gasket shape during installation and service, which is important on older transmissions where pan sealing surfaces can vary from wear and repeated maintenance. It is a strong match for long-tail searches such as transmission oil pan gasket for 1987 Chevrolet K10, 1975-1986 GMC K2500, or 1981-1991 Rolls-Royce Silver Spirit applications. The part number W39341TC is also useful when cross-checking service records or ordering by reference.

This part cross-references FEL-PRO TOS 18621 for the same application.

What This Gasket Helps Address

• Transmission fluid seepage at the oil pan rail
• Poor sealing after pan removal or service
• Gasket distortion on older transmission pans
• Leak concerns on 13-bolt-hole pan designs
• Replacement needs for classic Chevrolet, GMC, Jaguar, and Rolls-Royce vehicles

Installation Notes and Tips

Clean the pan rail and transmission case thoroughly before installation. Check the pan for bends, dents, or uneven bolt holes, since those conditions can affect sealing on cork-based gaskets. Tighten fasteners evenly in a crisscross pattern and avoid over-torquing, which can compress the gasket unevenly. Confirm the transmission pan uses a 13-bolt-hole layout and verify the application notes for your vehicle before ordering. For fitment searches, this gasket is commonly referenced for vehicles such as the Chevrolet Blazer, GMC Jimmy, and Jaguar XJS.
