A Guide to the Automatic Transmission Mount for 2020-2024 Nissan Altima
Experiencing vibrations or clunking noises in your Altima? It might be a failing transmission mount.
- The most common signs of a failing transmission mount are heavy vibrations at idle and clunking noises during acceleration.
- Vibration can also be a sign of a more serious engine bearing issue covered by a recall on some 2019-2020 models, so proper diagnosis is critical.
- OEM mounts offer the best ride quality, while aftermarket brands like Anchor are cheaper but may increase cabin vibration.
- Replacing a transmission mount requires supporting the transmission with a jack, a task that can be done by an experienced DIYer.
Is Your Altima Shaking or Making Noise?
When an automatic transmission mount fails on a 2020-2024 Nissan Altima, the signs are often noticeable. The rubber part of the mount can crack, wear out, or become saturated with leaking fluids, losing its ability to absorb vibrations and secure the transmission. If you notice any of the following symptoms, a bad mount could be the culprit.

- Excessive Vibration: This is the most common sign. You might feel a strong vibration in the steering wheel, floor, or seats, especially when the car is idling in Drive or Reverse.
- Clunking or Thudding Noises: Loud clunks, bangs, or thuds when you accelerate, brake, or shift gears are a red flag. This sound is the transmission moving and hitting the car's frame because the mount is no longer holding it securely.
- Jerky Shifting: A worn mount can allow the drivetrain to move too much, causing a lurch or jerk when the transmission shifts gears.
Could It Be Something Else?
Vibrations and noises can also be symptoms of other issues. For the 2019-2020 Altima with the VC-Turbo engine, Nissan issued a recall for defective engine bearings that can cause engine failure, with vibrations being a key warning sign. It's important to correctly diagnose the problem, as engine issues are more severe.
Choosing the Right Aftermarket Mount
When replacing your Altima's transmission mount, you'll face a choice between Original Equipment Manufacturer (OEM) parts and aftermarket options. For the 2020-2024 Altima, the primary aftermarket brand available is Anchor.
- OEM (Nissan): These are the exact same parts your car was built with. They guarantee a perfect fit and the intended level of vibration absorption. However, they are the most expensive option.
- Aftermarket (Anchor): Brands like Anchor offer a significant cost saving. However, the quality can be inconsistent. Forum users and general reviews often report that some aftermarket mounts use a harder rubber compound. While this may make them seem durable, it can lead to more engine vibration being felt inside the car compared to the softer OEM rubber. Fitment can also occasionally be an issue with aftermarket parts.
Pro Tip: If you want to maintain the original smooth ride of your Altima, the OEM mount is the safest bet. If you are on a tight budget and can tolerate a potential increase in cabin vibration, an aftermarket mount from a brand like Anchor can be a cost-effective solution.

Can I replace the transmission mount myself?
Yes, this is possible for a DIY mechanic with the right tools.

If you are not comfortable with this procedure, it is best to have a professional mechanic do the job.

It's a good practice, but not always necessary. When one mount fails, it puts extra stress on the others, which can cause them to fail sooner.
