Chevrolet Camaro Transmission Mount Guide: 2017-2024 Models
Experiencing clunks or vibrations in your Camaro? It might be a failing transmission mount.
- Vibrations in your Camaro could be a simple transmission mount, but don't rule out known transmission shudder issues (TSB 18-NA-355) before buying parts.
- Symptoms include clunking noises when shifting, excessive vibration at idle and during acceleration, and a feeling of drivetrain movement.
- Economy aftermarket brands like Anchor and DEA are a budget fix, but OEM/Genuine GM parts provide the best performance and vibration damping for a smoother ride.
- Replacement is a feasible DIY project for those with the right tools and can save on labor costs.
Is Your Camaro's Transmission Mount Failing?
A worn-out transmission mount on a Camaro can be felt more than it is seen. Because this part's job is to absorb vibration, its failure results in a rougher ride and unusual noises. These symptoms can often be confused with other issues, so it's important to know what to look for.
🎬 Watch: How to diagnose a bad motor or transmission mountCommon Symptoms of a Bad Mount:
- Excessive Vibration: You may feel a new, persistent vibration through the floor, seat, or steering wheel, especially when accelerating or idling in gear.
- Clunking Noises: Loud clunks or bangs when you shift from Park to Drive or Reverse, or during hard acceleration, are a classic sign. This is the sound of the transmission moving excessively and hitting other components.
- Drivetrain Movement: In some cases, you might feel the engine and transmission lurch or jerk when you accelerate or brake suddenly. This indicates the mount is no longer holding the transmission securely.
Important: Don't Confuse Mount Failure with Other Known Issues
While a bad mount causes vibration, your Camaro might have other issues with similar symptoms. No recalls or technical service bulletins (TSBs) exist specifically for the transmission mount on these models. However, be aware of the following:
- 8-Speed Transmission Shudder (2017-2019 models): Many Camaros with the 8-speed automatic transmission can develop a shudder or vibration during light acceleration. This is a known issue related to the original transmission fluid and is covered by TSB 18-NA-355. 🎬 See this video for a fix to the 8-speed shudder The fix often involves a fluid flush or, in severe cases, a torque converter replacement.
- 10-Speed Transmission Recall (2020-2022 models): Certain Camaros with the 10-speed automatic were recalled (NHTSA Recall 25V-148) for a faulty transmission control valve that could, in rare cases, cause harsh shifting or momentary wheel lock-up.
If you experience a persistent shudder, check with a dealer to see if these service bulletins or recalls apply to your vehicle before replacing the transmission mount.
Choosing the Right Aftermarket Mount
When shopping for a new aftermarket transmission mount, you'll find a few options that differ in quality and price.
- OEM / Genuine GM: This is the highest quality and most expensive option. It is identical to the part your Camaro was built with and offers the best vibration absorption and longevity. If you use your Camaro for performance driving or want the smoothest ride, OEM is the recommended choice.
- Economy Aftermarket (Anchor, DEA): Brands like Anchor and DEA (also known as DEA Products) are budget-friendly options. While they will secure your transmission, forum discussions indicate they may use harder rubber, which can lead to more noticeable cabin vibration compared to OEM. Their lifespan may also be shorter. These are a practical choice for a daily driver on a tight budget, but not ideal for a highly tuned or tracked vehicle.
Mechanic's Recommendation
For a performance car like the Camaro, the difference in ride quality is noticeable. While economy mounts fit a budget, spending more on an OEM or premium aftermarket mount often provides a better long-term result with less vibration. The labor to replace the part is the same regardless of which one you choose.
Cost to Replace a Camaro Transmission Mount
The cost can vary depending on the part you choose and local labor rates. The replacement itself is relatively simple for a mechanic.
| Item | Estimated Cost |
|---|---|
| New OEM Mount | $150 - $245 |
| New Aftermarket Mount (Economy) | $15 - $26 |
| Shop Labor | $85 - $150 |
| Total Estimated Cost (Shop) | $100 - $400 |
Frequently Asked Questions
Is replacing the transmission mount a DIY job?
Yes, for someone with moderate mechanical skill and the right tools. The basic process involves safely lifting the vehicle, supporting the transmission with a jack, unbolting the transmission crossmember, and then swapping the mount. It typically takes about 1-2 hours. You will need a good socket set, torque wrench, and jack stands.
🎬 Watch this walkthrough for changing the transmission mount yourselfCan I drive my Camaro with a bad transmission mount?
You can, but it is not recommended for an extended period. A completely failed mount can allow for excessive movement, which puts stress on engine mounts, driveshaft connections, and exhaust components, potentially leading to more expensive repairs.
Will an economy aftermarket mount feel different than OEM?
Possibly. Many users in online forums report that budget-friendly mounts from brands like Anchor or DEA can transmit more vibration into the car's cabin than the original GM part. This is often due to the use of a harder rubber compound. While they function to hold the transmission, the ride may not be as smooth.
How do I know if I have a bad mount or the 8-speed shudder issue?
A bad mount typically causes a 'clunk' when shifting into gear or during abrupt acceleration. The 8-speed transmission shudder (TSB 18-NA-355) is usually felt as a vibration or shake during light, steady acceleration, often between 25-80 mph. If the vibration feels more like driving over rumble strips, it is likely the transmission shudder, not the mount.
