Muffled Clatter Type Noise Coming from Center of Passenger Compartment (Replace Transmission Mount Assembly)
Models:
1997-98 Chevrolet Corvette Built Prior to VIN Breakpoint W512O351
Condition
Some customers may comment about a muffled clatter type noise coming from the center of the passenger compartment, just rearward of the driver and
passenger seats. This condition is most apparent when the vehicle is operated at low speeds over an irregular road surface with repetitive small bumps,
such as a "rumble strip".
Cause
Condition may be caused by internal valve noise of the hydraulic mount assembly being transmitted into the vehicle body structure.
Correction
Replace existing Rear Differential/Transmission Mount Assembly with a new assembly, P/N 22178940, following the service procedure as outlined in
the Service Manual, Section 4 (Driveline/Axle).
