A transmission mount helps support and locate the transmission. It also isolates driveline vibration from the frame and body and limits how far the drivetrain moves under load. Signs a mount may need replacing include:

• a clunk when accelerating, decelerating or shifting
• added vibration at idle
• visible drivetrain movement
• cracked or separated rubber

Diagnose the cause before replacing, since other components can produce similar symptoms.
