Transmission Mount Replacement Cost Ranges from $200 to $800 Depending on Your Vehicle

A transmission mount holds your transmission in place and absorbs vibration from the engine. When it wears out, you'll feel excessive shaking or clunking when you shift gears or accelerate. Replacing it costs between $200 and $800 total, though the range depends heavily on your vehicle's make, model, and engine type.

The part itself usually runs $50 to $300. Labor is where the cost spreads out — a straightforward replacement on an accessible mount might take a mechanic 1 to 2 hours, while a mount buried deep in the engine bay can take 4 to 6 hours. At typical shop rates of $75 to $150 per hour, labor alone can swing the total by several hundred dollars.

Luxury vehicles, trucks with larger engines, and front-wheel-drive cars with cramped engine compartments tend to land on the higher end. A Honda Civic mount replacement might cost $300 to $450, while a BMW or a full-size truck could reach $600 to $800.

Key Takeaways

  • Transmission mount replacement typically costs $200 to $800 total, split between the part ($50 to $300) and labor (1 to 6 hours at $75 to $150 per hour).
  • Your vehicle's make, model, and engine size determine how accessible the mount is and how long the job takes.
  • Some vehicles have multiple transmission mounts, and a mechanic may recommend replacing more than one if others show wear.
  • Getting a quote from a local shop is more reliable than a general range, because labor rates and part availability vary by region and dealer.

Why Labor Time Varies So Much Between Vehicles

The transmission mount sits between the transmission and the frame. On some vehicles, a mechanic can reach it by removing the wheel well or a plastic cover. On others, the engine, exhaust, or suspension components have to come out first.

Front-wheel-drive cars often have tight engine bays where the mount is wedged between the transmission and the firewall. Rear-wheel-drive trucks sometimes have the mount more exposed but require lifting the entire vehicle and supporting the transmission with a jack during removal. All-wheel-drive vehicles add another layer of complexity because the transfer case or additional drivetrain parts may be in the way.

A mechanic will also check whether the rubber has straightforward cracked or whether metal brackets have bent or rusted. If brackets are damaged, the replacement cost can jump because new brackets have to be welded or bolted in place, adding another hour or two of labor.

What You'll Pay at Different Types of Shops

Independent mechanics typically charge $75 to $120 per hour and source parts from aftermarket suppliers, keeping the total lower. A transmission mount replacement might run $250 to $500 at an independent shop.

Dealerships charge $100 to $150 per hour and use OEM (original equipment manufacturer) parts, which are more expensive but may provide to fit your exact vehicle. The same job at a dealership often costs $400 to $700.

Chain shops like Firestone or Midas fall in the middle — $80 to $130 per hour labor with a mix of OEM and quality aftermarket parts. You'll usually see quotes in the $300 to $600 range. Some chain shops also offer warranties on parts and labor, which can justify a slightly higher upfront cost.

Signs Your Transmission Mount Is Failing

A worn transmission mount produces specific symptoms. You'll feel a clunk or thud when you shift from Park to Drive or Reverse, especially if the engine is cold. The vehicle may shake noticeably when you accelerate hard or when the transmission downshifts on the highway.

In some cases, the engine rocks visibly side to side when you're stopped at a red light with your foot on the brake. If the mount has failed completely, you might hear metal-on-metal grinding or see the transmission has shifted position under the hood.

These symptoms can also point to worn engine mounts, a bad motor mount, or suspension issues, so a mechanic should inspect the vehicle before you commit to a transmission mount replacement. A visual inspection usually takes 15 to 30 minutes and costs $50 to $100, or is sometimes free if you're getting a full quote.

Whether You Should Replace Multiple Mounts at Once

Most vehicles have two to four transmission mounts — one on each side and sometimes one at the front or rear. If one has failed, the others are usually the same age and may be close behind. A mechanic might recommend replacing all of them while the transmission is already accessible, rather than paying for labor twice in the next year.

Replacing two mounts instead of one adds $100 to $200 in parts cost but often only adds 30 to 60 minutes of labor, since the hardest part is accessing the area. If your mechanic quotes $400 for one mount and $550 for two, the second one is worth doing. If the quote jumps to $700 for two, ask whether both are actually worn or if one can wait.

Request a written estimate that lists which mounts are being replaced and why. A good mechanic will show you photos of the failed mount and explain which others show visible cracking or separation.

How to Get an Accurate Quote for Your Vehicle

Call three shops — an independent mechanic, a dealership, and a chain shop — and give them your vehicle's year, make, model, and current mileage. Ask for a written quote that includes the part cost, labor hours, and total. Do not rely on online calculators, because they cannot account for your specific vehicle's layout or regional labor rates.

When you call, mention the symptoms you're experiencing (clunking, shaking, or visible movement). A shop that asks follow-up questions about when the noise happens and whether it's worse in cold weather is more likely to diagnose correctly than one that quotes you sight unseen.

If a shop's quote is significantly lower than the others, ask why. It might mean they use cheaper aftermarket parts, they're quoting fewer mounts, or they've underestimated the labor. A quote that's significantly higher might include a warranty or additional inspections you don't need.

Frequently Asked Questions

Can I drive with a bad transmission mount?

You can drive short distances, but it's not safe long-term. A severely worn mount can allow the transmission to shift position, which can damage transmission lines, the cooling system, or the driveshaft. The excessive vibration also stresses other engine components. Have it inspected and repaired within a week or two of noticing symptoms.

Is a transmission mount the same as an engine mount?

No. Engine mounts hold the engine in place; transmission mounts hold the transmission. A vehicle has both, and they can fail independently. Symptoms overlap — both cause shaking and clunking — so a mechanic needs to inspect both during diagnosis.

Do I need OEM parts or can I use aftermarket?

Quality aftermarket mounts work well and cost $50 to $150 less than OEM parts. OEM mounts are may provide to match your vehicle's exact specifications and usually come with a longer warranty. For most vehicles, a reputable aftermarket mount is a reasonable choice if cost matters.

Will my warranty cover transmission mount replacement?

Factory warranties typically cover transmission mounts for 3 years or 36,000 miles. Extended warranties vary — some cover wear items like mounts, others do not. Check your warranty paperwork or call your dealer to confirm before paying out of pocket.

How long does the repair actually take?

Most shops can complete a single transmission mount replacement in one business day. If multiple mounts are being replaced or if the mechanic finds additional damage during removal, the job might take two days. Ask the shop for a timeline when you drop off the vehicle.
