1989-1993 Buick Regal Automatic Transmission Mount: A Complete Guide
Stop the shaking and clunking noises in your Regal by understanding and replacing your transmission mount.
- Symptoms of failure include clunking noises when shifting, excessive vibration, and visible engine movement.
- Westar is an affordable aftermarket option, but may not have the same material quality as the original part.
- It is highly recommended to inspect the other engine and torque mounts, as they are likely worn if the transmission mount has failed.
- No recalls or TSBs were found specifically for the transmission mount on 1989-1993 Regals.
Is Your Regal Shaking or Making Clunking Noises?
If your 1989-1993 Buick Regal has developed a new vibration or makes a loud "clunk" when you shift into gear, a worn-out automatic transmission mount is a likely culprit. Over decades of use, the rubber in the mount can crack, collapse, or become soaked with leaking fluids, causing it to fail. When this happens, the transmission is no longer held securely, leading to a number of noticeable problems.
Symptoms of a Failing Transmission Mount
- Excessive Vibration: You may feel a strong vibration through the floor, seats, or steering wheel, especially when the car is idling in gear or during acceleration.
- Clunking or Banging Noises: Loud clunks or bangs are common when you shift from Park to Drive or Reverse. You might also hear noises when you accelerate hard or brake suddenly as the transmission shifts and hits against the frame.
- Excessive Engine Movement: If you have a helper put the car in gear while holding the brake, you may be able to see the engine and transmission assembly rock or lift significantly more than usual.
Choosing the Right Aftermarket Mount
For a vehicle like the 1989-1993 Regal, finding an original equipment (OEM) transmission mount from GM is highly unlikely. The most common and practical option is a new aftermarket part. Westar is a widely available brand for this application.
Westar Mounts: Westar is generally considered a standard, economy-tier replacement brand. Reviews from mechanics and DIYers are mixed. Some users report that the metal can be thinner and the rubber harder than the original OEM part, which might affect long-term durability. However, other users find the quality acceptable for the price, especially for a daily driver, and report that it successfully eliminates the symptoms of a bad mount. For a Regal from this era, a Westar mount is an affordable way to restore the vehicle's drivability.

Frequently Asked Questions (FAQ)
Can I replace the transmission mount myself?
Yes, this is a DIY-feasible job for someone with basic mechanical skills and tools. The process involves safely supporting the transmission with a floor jack and a block of wood, unbolting the old mount from the frame and the transmission, and then installing the new one. Always use jack stands for safety.
What happens if I don't replace a bad transmission mount?
Ignoring a failed mount allows the transmission to move excessively. This can put stress on other parts, including the CV axles, exhaust system, coolant hoses, and other drivetrain mounts, leading to more expensive repairs down the road. In very severe cases, it can cause shifting problems or even transmission fluid leaks.
Is a transmission mount the same as an engine mount?
They are not the same, but they perform a similar function. Engine mounts secure the engine, while the transmission mount secures the transmission. Together, they hold the entire powertrain in place. Your Regal has both engine and transmission mounts.
Were there any recalls for the transmission mount on my Regal?
Searches of the National Highway Traffic Safety Administration (NHTSA) database did not find any specific recalls or technical service bulletins (TSBs) for the automatic transmission mount on the 1989-1993 Buick Regal.
