Transmission Mount Replacement Cost & Pricing
Replace the worn transmission mount that supports the rear of the transmission and absorbs drivetrain vibration. A failed mount causes vibration, clunking on gear changes, driveshaft angle issues, and excessive strain on the transmission case.
Typical Transmission Mount Replacement cost
$160–$580, with an average estimate of $300 before vehicle-specific adjustments.
What to expect
Difficulty: easy. Typical labor time: 1–3 hours.
Mechanic's tip
Transmission mounts are often overlooked when diagnosing vibration and clunking — they're checked less frequently than motor mounts. Replace the transmission mount when doing motor mounts since the symptoms overlap and the vehicle is already on a lift. RWD and 4WD vehicles with a separate transfer case often have additional crossmember mounts that should be inspected at the same time.
