Transmission Pan Gasket Chrysler 904 Torqueflite

The Transmission Pan Gasket Chrysler 904 Torqueflite from COMETIC GASKETS is an essential component for anyone maintaining or rebuilding a Chrysler A-904 automatic transmission. This gasket seals the transmission pan to the main transmission body, preventing fluid leakage that can lead to overheating, loss of hydraulic pressure, and catastrophic transmission failure. Whether you're performing routine maintenance on a classic Mopar, restoring a vintage performance build, or repairing a modern Chrysler vehicle equipped with this legendary three-speed unit, a quality replacement gasket is non-negotiable for long-term reliability.

Engineered by COMETIC GASKETS, this transmission pan gasket features a 0.060-inch thick rubber-coated aluminum construction that provides superior sealing capability compared to stock cork or paper gaskets. The aluminum core delivers structural rigidity and heat dissipation, while the rubber coating creates a conformable seal that accommodates manufacturing tolerances and minor surface imperfections on both the pan and transmission case. This material composition ensures repeatable sealing performance across multiple assembly and disassembly cycles, making it ideal for builders who plan future service work or those converting to an aftermarket pan for increased fluid capacity and cooling benefits.

This gasket is compatible with all Chrysler 904 Torqueflite transmissions, including applications in Plymouth, Dodge, and Mopar vehicles from the 1960s through modern restorations. Installation requires standard gasket removal tools and surface preparation—cleaning both the pan and case of old gasket material and oil residue—ensuring maximum sealing integrity. The compact dimensions (13.5 x 16 inches) and minimal weight make it easy to handle during pan removal, and proper torque specifications to factory specs will guarantee a leak-free seal that withstands normal driving conditions and street performance use for years.
