Dodge Avenger Automatic Transmission Mount: A Complete Guide (2007-2014)
If your Avenger is vibrating or making clunking noises, a bad transmission mount could be the reason.
- Clunking noises when shifting and vibrations at idle are the top symptoms of a bad transmission mount.
- Aftermarket brands like Anchor, DEA, and Westar are affordable but may increase cabin vibration compared to OEM Mopar parts.
- Your Avenger has four powertrain mounts; if one has failed, the others are likely worn and should be inspected.
- Always confirm the part fits your specific engine (e.g., 2.4L, 3.6L) and transmission (4-speed, 6-speed) before buying.
Is Your Dodge Avenger Shaking or Making Clunking Noises?
A common issue for the 2007-2014 Dodge Avenger is the failure of its engine and transmission mounts. These parts are made of metal and rubber, and over time, the rubber breaks down from age, heat, and stress. When the automatic transmission mount fails, it can no longer support the transmission properly or absorb vibrations. This leads to noticeable symptoms that can make your car uncomfortable to drive.
Symptoms of a Failing Transmission Mount
- Excessive Vibration: You might feel a strong vibration through the steering wheel, floor, or seats. This is often worst when you're stopped at a light with the car in "Drive".
- Clunking or Thudding Sounds: A loud "clunk" or "bang" from the engine bay when you shift from Park to Drive/Reverse is a classic sign. You may also hear it when you accelerate or brake hard.
- Engine Movement: A bad mount allows the engine and transmission to lurch. You might feel or even see the engine move excessively if someone revs it while you look under the hood.
Known Issues & Recalls
As of early 2026, there are no specific safety recalls from the NHTSA for the transmission mounts on the 2007-2014 Dodge Avenger. However, there have been recalls for other issues like airbags and a potential park engagement problem on models with the 62TE transmission, so it's always good to check if your vehicle is affected by those.
Choosing the Right Aftermarket Mount: OEM vs. Aftermarket
When replacing your transmission mount, you have two main choices: OEM (Original Equipment Manufacturer) from Mopar or an aftermarket brand. OEM Mopar mounts are known for providing the best ride quality and durability, but they are also the most expensive option.
Aftermarket mounts from brands like Anchor, DEA, and Westar are much more affordable. However, forum discussions and mechanic reviews often point out that these brands may use a harder rubber compound. This can lead to a slight increase in cabin vibration compared to the original part, and they might not last as long. For many owners, the significant cost savings make this a worthwhile trade-off.
Pro Tip: Your Avenger has four mounts in total (front, rear, right-side, and the left-side transmission mount). When one fails, it puts extra stress on the others. It's a good idea to inspect all of them and consider replacing them as a set for a longer-lasting repair.
Cost to Replace a Dodge Avenger Transmission Mount
| Part Type | Estimated Cost (Part Only) |
|---|---|
| New Aftermarket (e.g., Anchor, DEA, Westar) | $41.16 - $127.83 |
| New OEM (Mopar) | $100 - $310+ |
| Shop Labor | $100 - $250 |
Cost estimates are approximate and can vary by location and specific mount. Labor costs can be higher for mounts that are more difficult to access.
Frequently Asked Questions (FAQ)
Can I drive my Avenger with a bad transmission mount?
You can usually drive it gently to a repair shop, but it's not recommended for long. Continued driving can put stress on other parts like axles, hoses, and the exhaust system, leading to more expensive repairs.
How hard is it to replace a transmission mount myself?
Replacing the transmission mount is a moderately difficult job for a DIY mechanic. It requires safely supporting the engine and transmission with a jack and a block of wood, and then unbolting the old mount and installing the new one. Some bolts can be in tight spaces, requiring patience and the right tools like socket extensions and ratchets.
How do I know which mount to buy for my Avenger?
The 2007-2014 Avenger came with different engines (2.4L, 2.7L, 3.5L, 3.6L) and transmissions (4-speed or 6-speed). The mounts are specific to these combinations. Always verify the part fits your exact year, engine, and transmission before ordering.
Will an aftermarket mount make my car vibrate more?
Possibly. Budget-friendly aftermarket brands often use harder rubber than OEM parts, which can transmit more vibration into the cabin. While many drivers find it acceptable for the cost savings, if your goal is to restore the original smooth ride, an OEM Mopar part is the safer bet.
