•  Location: Between the rear transmission cover and main gearbox housing
•  Function: Provides an oil-tight seal at the transmission end cover to prevent fluid leaks and contamination
•  Symptoms of Failure: Oil leaks, low gearbox oil, dirty housing
•  Benefits: OEM fit, durable sealing, long-term leak prevention

Transmission cover gaskets naturally deteriorate over time due to heat, oil pressure, and age.
Failure can lead to:
•  Gear oil seepage or visible leaks at the case seam
•  Low transmission fluid levels
•  Premature bearing or synchronizer wear due to oil loss

Replace during:
•  Gearbox rebuild or overhaul
•  Any service requiring removal of the transmission cover
•  Preventive maintenance when oil leaks or gasket hardening are detected

Replacing with the OE Match 95030135102 gasket ensures a secure, factory-quality seal for long-term gearbox reliability.
