Nissan Quest 1993-2003 Automatic Transmission Mount: A Complete Guide
Stop the clunks and vibrations in your Quest by understanding and choosing the right transmission mount.
- A clunking noise when shifting and new vibrations at idle are the most common signs of a failed transmission mount.
- For an older Quest, budget-friendly aftermarket brands like Anchor, DEA, and Westar are a practical choice, but may not last as long as OEM.
- The 1993-1998 Quest is different from the 1999-2002 models; ensure you buy the correct part for your year.
- While you can drive with a bad mount, ignoring it can lead to damage to other parts like axles, hoses, and exhaust components.
Is Your Quest's Transmission Mount Failing?
A bad transmission mount is a common issue on older vans like the 1993-2003 Quest. Because the rubber in the mount degrades over time from heat, stress, and exposure to the elements, it eventually cracks, sags, or tears. When this happens, you'll likely notice some distinct symptoms.
Key Symptoms of a Bad Transmission Mount:
- Clunking or Thudding Noises: A loud "clunk" or "thud" when you shift from Park into Drive or Reverse is a classic sign. You might also hear this noise when you accelerate or brake suddenly as the transmission shifts and hits other parts.
- Excessive Vibration: If your mount is worn, you may feel a new or increased vibration throughout the vehicle, especially when idling at a stoplight. This shaking can be felt in the steering wheel, floor, or seats.
- Visible Movement: A mechanic can often diagnose a bad mount by watching the engine and transmission while shifting gears with the brakes applied. Excessive movement indicates the mount is no longer holding the transmission securely.
Generation Note: Two Different Quests
The 1993-2003 Nissan Quest covers two distinct generations. The 1993-1998 models were a joint venture with Ford and are mechanically similar to the Mercury Villager. The 1999-2002 models are a separate Nissan design (there was no 2003 model year). Parts are not interchangeable, so always confirm the part fits your specific year before ordering.
Choosing the Right Aftermarket Mount
For a vehicle of this age, an aftermarket transmission mount is a cost-effective choice compared to an expensive OEM part. The main brands available—Anchor, DEA, and Westar—are considered value or economy-tier options.
Here’s an honest breakdown:
- OEM (Original Equipment Manufacturer): The original Nissan part offers the best fit and vibration damping, but it is the most expensive and may be difficult to find for an older vehicle.
- Aftermarket (Anchor, DEA, Westar): These brands provide a budget-friendly solution. However, online forums and reviews show mixed experiences. Some users report they work fine for an older vehicle, while others mention a shorter lifespan or a slight increase in vibration compared to the original part. This is often because they use a harder rubber compound. For a daily driver where budget is a key concern, these brands are a practical choice.
Pro Tip: Your Quest has multiple motor and transmission mounts (typically four). When one fails, the others have experienced the same amount of wear. A mechanic will often recommend replacing the main mounts in pairs or as a set to restore a smooth ride and avoid another repair job in the near future.

Frequently Asked Questions
How can I be sure my transmission mount is bad?
The most common signs are clunking noises when shifting, excessive vibration at idle, and a thudding sound on acceleration. A visual inspection may show cracked or separated rubber. The definitive test, often done by a mechanic, is to hold the brakes, shift into gear, and lightly apply the throttle to see if the engine and transmission move excessively.
Can I replace the transmission mount myself?
Yes, this is a feasible DIY job for someone with mechanical experience. It requires safely supporting the vehicle on jack stands and using a floor jack with a block of wood to support the transmission while you unbolt the old mount and install the new one. You will need a good set of metric sockets and wrenches.
