Transmission Pan Gasket Kit

The FEL-PRO Transmission Pan Gasket Kit (TOS 18608) is a direct-fit replacement gasket engineered for Powerglide transmissions, addressing one of the most common fluid leaks experienced by classic car builders and daily-driver enthusiasts. This composite gasket kit eliminates the frustration of seeping transmission fluid around the pan perimeter—a leak that, left unchecked, leads to low fluid levels, overheating, and costly internal transmission damage. Whether you're restoring a vintage muscle car, maintaining a reliable street machine, or diagnosing an existing drip, this OEM-specification gasket restores the seal integrity your transmission demands.

Constructed from advanced composite material with a non-stick, self-sealing design, the Transmission Pan Gasket Kit resists common failure modes that plague rubber or cork alternatives. The non-stick surface prevents the gasket from adhering permanently to the pan or transmission body, allowing for clean removal during future service intervals without material tearing or residue left behind. The composite construction maintains its compression set across normal transmission operating temperatures, delivering a consistent, reliable seal across all bolt positions. FEL-PRO's engineering ensures precise dimensional accuracy—critical for maintaining the critical seal along the pan's bolt-hole pattern and perimeter edges.

Mechanics and restoration shops trust FEL-PRO gaskets for their durability and ease of installation. This kit is the factory choice for Powerglide transmission service on vintage Chevrolet, Pontiac, and other GM platforms that relied on this legendary two-speed automatic. Installation requires only standard pan removal, gasket cleanup, and torque-to-spec bolt sequence—no special tools or transmission overhaul expertise needed. Keep a Transmission Pan Gasket Kit on hand for any Powerglide service, or order now to cure that slow seep before it becomes an emergency.
