Transmission pan gaskets are a frequent maintenance touchpoint on AOD, AODE, and 4R70W transmissions, yet the factory cork composite gaskets split, compress unevenly, and require messy sealant every time the pan comes off. Moroso's rubber-over-steel pan gasket eliminates those frustrations with a reusable, sealant-free design built to outlast OEM and inferior aftermarket alternatives through multiple service intervals.
Vulcanized rubber bonded to a rigid steel carrier. The 40 durometer rubber compound is vulcanized directly onto a steel frame, giving the gasket enough rigidity to seat flat and enough compliance to seal without torque-sensitive sealant. The full 3/16-inch thickness provides consistent crush across the entire perimeter of the pan flange.
No sealant required. Because the gasket creates a complete seal on its own, pan removal and reinstallation becomes a clean, straightforward job. There is no gasket compound to scrape from mating surfaces and no cure time to wait for before refilling the transmission.
Built to outlast cork composites. Cork and composite gaskets absorb fluid over time, swell unevenly, and crack when disturbed. The rubber and steel construction here resists fluid absorption and returns to its original shape after the pan is reinstalled, which means it survives repeated service intervals without replacement.
Product Benefits
- Vulcanized Construction: 40 durometer rubber bonded to a steel frame for a consistent, leak-free seal.
- Full 3/16-Inch Thickness: Provides even compression across the entire pan flange.
- Sealant-Free Installation: No gasket compound needed, speeding up removal and reinstallation.
- Reusable Design: Outlasts cork composites and survives multiple service intervals.
- Rigid Steel Carrier: Keeps the gasket flat during installation and prevents distortion under load.
- One Per Package: Includes everything needed to reseal the transmission pan.
Note: Fits AOD, AODE, and 4R70W transmissions. Gaskets may arrive blue or black as inventory transitions to all-black silicone for this part number.
