Is a transmission mount expensive to fix?
Typically, replacing a transmission mount is not a major drivetrain repair, and in most cars the total bill stays in the low-to-mid hundreds. Parts are usually affordable, while labor can drive the total depending on accessibility and location.
What the transmission mount does
The transmission mount anchors the transmission to the vehicle’s frame and dampens vibration so the drivetrain runs smoothly. Over time rubber decays, hydraulic mounts leak, and metal components can crack or tear, allowing movement that shows up as vibration, clunking, or misalignment.
Common symptoms of failure
- Excessive vibration or movement felt in the cabin, especially at idle or under load
- Clunking, banging, or thumping noises when shifting gears or going over bumps
- Noticeable engine or transmission movement within the engine bay
- Visible cracks, deformation, or separation on the mount
- Shift delays or rough shifting if the mount isn’t holding the transmission in place
When you notice these signs, it’s wise to have a quick inspection to confirm whether the mount is the culprit or if other drivetrain components are involved.
Cost overview
Here is a breakdown of typical costs you can expect for a single transmission mount replacement. Prices vary by vehicle and region, and some cars need more than one mount.
- Parts: roughly $20–$250 per mount (rubber mounts are cheaper; hydraulic or OEM-quality mounts can be more expensive)
- Labor: typically $100–$500, depending on local shop rates and how long the job takes
- Total: most single-mount replacements fall in the $150–$800 range, with higher-end or multi-mount jobs approaching or exceeding $1,000
In general, most drivers pay a few hundred dollars for a single-mount replacement, while more expensive vehicles or jobs that involve multiple mounts, substantial exhaust and driveshaft work, or difficult access can push the bill higher.
Factors that affect price
Several variables determine the final bill for a transmission mount replacement.
- Number and type of mounts: some vehicles use one mount, others use two or three, and some mounts are hydraulic or semi-hydraulic with higher part cost
- Make, model, and engine configuration: luxury brands or unusual configurations may require special mounts or more labor
- Labor rates by region and shop: urban areas and dealer shops typically cost more
- Accessibility and complexity: if the mount sits behind exhaust components, under a subframe, or requires components to be removed to access it, labor increases
- Additional work found during service: leaks, torn mounts in adjacent pieces, or misalignment may add to the scope and price
Understanding these factors helps you compare quotes and plan for a repair that fits your budget and vehicle needs.
DIY vs professional replacement
You can save on labor by doing the job yourself, but transmission-mount replacement is a job that requires mechanical confidence and proper safety gear. Consider these points before you decide.
- Pros of DIY: lower labor cost, learning experience, flexibility in scheduling
- Cons of DIY: risk of injury, possible damage from incorrect mounting or torque settings, and potential warranty issues
- When to hire a professional: you’re unsure about tools or safety, your vehicle has multiple mounts or complex access, or you’d prefer a guaranteed inspection and warranty with the repair
Many drivers opt for a professional replacement to ensure correct alignment, torque specs, and to verify there are no related drivetrain issues after the mount is replaced.
What to expect during the repair
A typical replacement involves lifting or supporting the vehicle, securing the transmission, removing the old mount(s), installing the new mount(s), and rechecking clearances and torque. A test drive helps verify that the vibration and noises have subside and that no new issues have appeared.
Some jobs may require removing components such as an exhaust pipe, heat shields, or the crossmember to gain access, which can add to both time and cost.
Summary
Transmission mount replacement is usually a moderate-cost repair compared with other drivetrain work. Most drivers can expect a few hundred dollars in total, with the price rising for vehicles with multiple mounts, hydraulic designs, or limited access. If you notice persistent vibrations, clunks, or shifting irregularities, a professional inspection can confirm whether the mount is the culprit and help you plan a cost-effective fix.
