Chevrolet Camaro Manual Transmission Mount Replacement Guide (2017-2024)
If you're hearing clunks or feeling vibrations when you shift, your Camaro's transmission mount could be the problem.
- A clunking noise when shifting or accelerating is the number one sign of a failed mount on a Camaro.
- Budget aftermarket brands like Anchor and DEA are inexpensive but may have a shorter lifespan and cause more vibration than OEM.
- The OEM part number for the manual transmission mount is 84119729.
- This is a DIY-friendly repair that can be completed in under two hours with basic tools.
Is Your Camaro's Transmission Mount Failing?
A transmission mount is a wear-and-tear item. The rubber can crack, tear, or collapse from age and stress. For a high-performance car like the Camaro, aggressive driving and hard launches can shorten its life. If you notice any of the symptoms below, it's time to inspect your mount.
Key Failure Symptoms
- Clunking or Banging Noises: The most common sign is a loud clunk or bang when you accelerate, brake hard, or shift gears. This is the sound of the transmission moving too much and hitting the chassis.
- Excessive Vibration: You may feel a new or increased vibration through the floor, seats, or the gear shifter itself. This happens because the worn rubber can no longer absorb drivetrain vibrations.
- Shifter Movement: A key symptom in a manual Camaro is the shifter physically jumping or moving during acceleration.
- Rough Shifting: A bad mount can cause the transmission to sit at the wrong angle, making gear changes feel jerky or difficult.
Known Issues & Recalls
As of early 2026, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from Chevrolet for the manual transmission mount on the 2017-2024 Camaro. Searches of the NHTSA database did not show any actions for this specific part. A recall exists for some 2020-2022 Camaros related to the 10-speed automatic transmission, but this does not apply to manual transmission mounts.
Choosing the Right Aftermarket Mount
When replacing your mount, you have a few options. The choice between a budget aftermarket part and a genuine GM part depends on your priorities and driving style.
Budget Aftermarket (Anchor, DEA)
Brands like Anchor and DEA are economy-focused, offering a low price point. While they are designed to match the original part's fit, online forums and reviews suggest their quality can be inconsistent. Some users report these mounts failing much sooner than the original part or introducing more vibration into the cabin. These are a viable option if your main goal is to fix the immediate problem at the lowest possible cost, but they may not offer the same longevity or ride refinement as an OEM part.
OEM (Original Equipment Manufacturer)
The genuine GM mount (part number 84119729) is what your car came with from the factory. It is designed and tested by GM to balance performance, comfort, and durability. While it is the most expensive option, it is the safest bet for restoring the original ride quality and is generally expected to last the longest.
A Note on Polyurethane Mounts
You may see polyurethane (poly) mounts available from performance brands. These are much stiffer than the stock rubber mount. While they offer maximum durability and virtually eliminate drivetrain movement, they will transfer significantly more noise and vibration into the cabin. For a daily-driven car, most owners prefer the comfort of the stock rubber mount.
Cost of Replacing Your Transmission Mount
The cost to replace the transmission mount on a 2017-2024 Camaro is relatively low, especially if you can do it yourself. The part itself is affordable, and labor is straightforward.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Part (Anchor, DEA) | $15 - $30 |
| New OEM Part | $190 - $310 |
| Used OEM Part | $70 - $150 |
| Shop Labor | $100 - $200 |
Frequently Asked Questions
Is this a difficult repair to do myself?
No, for most DIY mechanics, this is a straightforward job. It requires safely lifting the car, supporting the transmission with a jack, removing a crossmember, and then swapping the mount. It typically takes 1 to 1.5 hours.
Can I drive with a bad transmission mount?
You can, but it's not recommended. Continuing to drive allows the transmission to move excessively, which can put stress on other components like engine mounts, driveshaft joints, and exhaust connections, potentially leading to more expensive repairs.
Will a bad mount cause a Check Engine Light?
It is very unlikely. A transmission mount is a mechanical part and does not have sensors. The symptoms are almost always physical (noise, vibration) rather than electronic.
Should I replace my engine mounts at the same time?
When a transmission mount fails, it can put extra stress on the engine mounts. It's a good idea to inspect the engine mounts when you replace the transmission mount. If they show signs of cracking or wear, replacing them at the same time can save you future labor costs.
