Transmission Mount Replacement Cost (2026 Guide)

📈 Average 2026 US Cost

$150 - $500

Most US drivers pay $200-$400 for this repair on a typical vehicle.

📈 What Affects The Price

Mount type: Solid rubber mounts $30-$80. Hydraulic mounts $80-$200. Fluid-filled units cost more but ride better.
Access: Most transmission mounts are accessible from below with a jack and jack stands.
Crossmember removal: Some FWD vehicles require dropping the rear crossmember - 30-60 minutes extra labor.
OEM vs aftermarket: OEM mounts last longer. No-name aftermarket can fail in 12-18 months.
Combined with engine mounts: If engine mounts are also bad, doing both saves on labor overlap.
AWD vs FWD vs RWD: AWD transfer case mounts are similar parts but tighter access.

🔒 How To Avoid Overpaying

Confirm it is the trans mount, not engine mounts, by watching where the powertrain moves under load.
Replace both ends if both are weak - labor stacks well.
Avoid the cheapest aftermarket mounts - rubber separation is common in under a year.
Check exhaust hangers at the same time - they fail at similar mileage.
Get 2-3 quotes - this job has wide pricing variation.
Keep an old mount for comparison so you know what wear looks like.
If you feel the clunk only on Park-to-Drive, this mount is usually the culprit.

💬 Frequently Asked Questions

How do I know my transmission mount is bad?

Hard clunk when shifting from Park to Drive or Reverse. Vibration through the floor at idle. Visible drooping of the transmission when viewed from below.

Is it dangerous to drive with a bad transmission mount?

Not immediately, but a fully broken mount lets the transmission move enough to damage the driveshaft, exhaust, or shift linkage.

Can I just replace one mount?

Yes - replace what is bad. But check the other mounts at the same time, since they age together.

How long does a transmission mount last?

75,000-150,000 miles typically. Hot climates, towing, and aggressive launches shorten the life.

Will replacing the mount fix my shift clunk?

If the clunk is from excess driveline movement, yes. If it is internal to the transmission, no - that is a different repair.
