727 Trans.Pan Gasket

The 727 Trans.Pan Gasket from MOPAR PERFORMANCE is engineered for TorqueFlite 727 automatic transmissions, a legendary platform that powered countless muscle cars, trucks, and performance vehicles from the late 1960s through the 1980s. This rubber-coated composite gasket seals the transmission pan to the main transmission housing, preventing fluid leakage that can compromise hydraulic pressure and transmission performance. Whether you're rebuilding a classic Mopar, restoring a vintage hot rod, or maintaining a high-mileage 727 in service, a quality pan gasket is essential to keep your trans running cool and leak-free.

This gasket features a rubber-coated composite construction that provides superior sealing compared to paper-only alternatives, especially when exposed to modern synthetic transmission fluids and elevated operating temperatures. The composite base material resists degradation from heat cycles, while the rubber coating creates a conformable seal that accommodates minor pan and housing surface irregularities—critical for older cast-iron pans that may have slight warpage. At just 0.22 lbs with compact dimensions of 12.15 x 0.85 x 16.35 inches, this gasket matches OEM specifications and installs using factory torque procedures without requiring special tools or extended soak times.

Mechanics and DIY builders trust MOPAR PERFORMANCE OEM-equivalent components for 727 transmission service because they eliminate comebacks and warranty concerns. This gasket is ideal for pan drops during fluid and filter changes, full transmission rebuilds, or addressing existing seepage on stock or mildly modified transmissions. Installation requires only a pan removal, cleaning of the sealing surface, and careful re-torquing to specification—a straightforward job that extends transmission life significantly when paired with fresh fluid and proper maintenance intervals.
