This guide clarifies why your Buick Regal has automatic transmission mounts, as no manual transmission was offered for this generation in North America.
- The 2004-2008 Buick Regal was only sold with an automatic transmission in North America; it does not use a 'manual transmission mount'.
- You are likely looking for an 'automatic transmission mount'.
- Key failure symptoms include clunking noises when shifting, excessive vibration at idle, and visible engine lurching.
- Replacing a bad mount is important to prevent stress and damage to other drivetrain components.
No Manual Transmission for the 2004-2008 Regal
If you are searching for a manual transmission mount for your 2004, 2005, 2006, 2007, or 2008 Buick Regal, it's important to know that one does not exist. During this production period, all Buick Regals sold in the North American market were manufactured exclusively with a 4-speed automatic transmission. Therefore, no OEM or aftermarket manual transmission parts were ever produced for this vehicle. You are likely looking for the automatic transmission mount.
Symptoms of a Failing Automatic Transmission Mount
The automatic transmission mounts on your Regal are designed to last a long time, but they can eventually wear out from age, heat, and stress. When a mount fails, the rubber cracks or collapses, and it can no longer hold the transmission securely. This can lead to several noticeable issues. The symptoms of a bad automatic transmission mount are very similar to those of a bad engine mount.
- Clunking or Thudding Noises: The most common symptom is a distinct "clunk" sound when you shift into Drive or Reverse. You may also hear this noise when accelerating or braking suddenly.
- Excessive Vibration: You might feel a new vibration in the steering wheel, floor, or seats, especially when the car is idling at a stoplight. This happens because the mount can no longer absorb the normal drivetrain vibrations.
- Engine Movement: In more severe cases, a failed mount allows the entire engine and transmission assembly to move or lurch during acceleration. An observer might see the engine physically shift under the hood when you rev it.
Don't Ignore a Bad Mount
While you can drive with a failing transmission mount, it's not recommended for long. A bad mount puts extra stress on other components like engine mounts, CV axles, and exhaust pipes. Ignoring the problem can lead to more expensive repairs down the road.

For a vehicle of this age, aftermarket parts provide a cost-effective solution for replacing your automatic transmission mounts. Several brands are available that offer reliable performance for daily driving.
- Standard Quality Brands: Brands like Duralast, Pioneer, and ACDelco are often considered good quality replacements that meet or exceed original specifications.
- Economy Brands: Brands such as Anchor, Westar, and DEA are widely available and very affordable, making them a popular choice for budget-conscious repairs.
Pro Tip: Transmission mounts and engine mounts often wear out at a similar rate. If you are replacing one, it is a good idea to inspect the others. Many retailers sell complete engine and transmission mount kits for a comprehensive repair.
Frequently Asked Questions (FAQ)
Did any Buick Regal come with a manual transmission?
Yes, but not in the 2004-2008 generation. Later generations of the Buick Regal, specifically the Regal GS models from 2011-2017, were available with a manual transmission option. The 2004-2008 models were strictly automatic.
Is it hard to replace an automatic transmission mount?
For a DIY mechanic with the right tools, this is a manageable job. It involves safely supporting the car on jack stands, supporting the transmission's weight with a floor jack, and then unbolting the old mount to install the new one. It is generally considered a low-to-moderate difficulty repair.
How do I know if it's a transmission mount or an engine mount?
The symptoms are nearly identical, and it can be difficult to distinguish between them. A common diagnostic technique is to have someone watch the engine for movement while you shift the car from Park to Drive and Reverse with the brake pedal held down firmly. Excessive movement can help pinpoint which mount has failed.
