A Guide to the Automatic Transmission Mount for the 1992-1998 Buick Skylark
If your Skylark clunks when you shift or vibrates excessively, your automatic transmission mount may be the culprit.
- A loud clunk when shifting or excess vibration are the most common signs of a failed mount.
- A TSB was issued for 1992-1996 models for mount replacement due to 'excess engine pull', suggesting a known issue from the factory.
- Aftermarket brands like Anchor, DEA, and Westar are affordable but have mixed quality reviews; Pioneer is often considered a higher-quality alternative.
- Continuing to drive with a bad mount can cause damage to other components like axles, hoses, and other mounts.
Symptoms of a Failing Transmission Mount
A bad transmission mount will give you clear signs that it needs attention. Because the part is designed to absorb vibration and prevent movement, its failure results in noticeable sounds and sensations.
- Clunking or Banging Noises: The most common symptom is a loud "clunk" or "bang" when you shift gears, especially from Park to Drive or Reverse. You may also hear this noise during hard acceleration or braking as the transmission shifts around.
- Excessive Vibration: You might feel a new or increased vibration through the floor, steering wheel, or seats. This vibration is often worse when the car is idling in gear or during acceleration. Some owners of similar vehicles report vibration at highway speeds, like 60-70 mph.
- Visible Engine Movement: If you have a helper put the car in gear and hold the brake while lightly pressing the gas, you may see the engine and transmission assembly move or rock excessively under the hood. This is a sure sign of a bad mount.
Vehicle-Specific Known Issues
While no specific safety recalls have been issued by the NHTSA for the transmission mount itself on the 1992-1998 Skylark, a General Motors Technical Service Bulletin (TSB) exists for 1992-1996 models concerning "transaxle mount replacement due to excess engine pull." This indicates that the factory was aware of potential issues with the original mounts. A separate recall was issued for the 1992 model year for a misadjusted park lock cable, but this is unrelated to the mount itself.
Choosing the Right Aftermarket Mount
When replacing the transmission mount on an older vehicle like the Skylark, the original OEM part may be discontinued or expensive. Aftermarket parts offer a cost-effective solution. However, quality can vary between brands.
Pro Tip: It is often recommended to replace all engine and transmission mounts at the same time. A new, stiff transmission mount paired with old, worn engine mounts can put extra stress on the remaining old parts.
Aftermarket Brand Tiers
Based on reviews and forum discussions, aftermarket mounts for this vehicle generally fall into a few categories:
- Good Quality Aftermarket (Pioneer Cable): Some mechanics and DIYers have noted that Pioneer mounts are often very close in quality and appearance to the original factory parts. They are a solid choice if available.
- Economy Brands (Anchor, DEA, Westar): These brands are widely available and very affordable. They are a practical choice for budget-conscious repairs. However, online forums contain mixed reviews; some users find them to be perfectly adequate, while others report issues with material quality, premature failure, or slight differences in fit compared to the original part. When using these brands, inspect the part before installation to ensure it looks well-made.
Estimated Replacement Costs
The cost to replace the transmission mount can vary based on whether you do it yourself or have a professional mechanic do the work.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Part | $22.90 - $32.45 |
| Shop Labor | $100 - $200 |
| Total (Shop) | $125 - $235 |
Frequently Asked Questions
Can I drive with a bad transmission mount?
You can, but it is not recommended for an extended period. A failed mount allows for excessive movement which puts stress on other parts like CV joints, axles, hoses, and wiring. Addressing it sooner rather than later can prevent more expensive repairs.
How can I check if my transmission mount is bad?
You can perform a visual inspection by looking for cracks, tears, or separation in the rubber part of the mount. You can also have a helper hold the brakes and shift from Drive to Reverse to see if the engine/transmission assembly moves excessively. The vehicle should be safely supported on jack stands for any under-car inspection.
What causes a transmission mount to fail?
Mounts are made of rubber that degrades over time due to age, heat from the engine, and exposure to fluids like oil or transmission fluid. Hard driving with abrupt acceleration can also put extra stress on the mounts, causing them to wear out faster.
Is a transmission mount the same as an engine mount?
They perform a similar function but are in different locations. Engine mounts support the engine, while the transmission mount supports the transmission. Together, they hold the entire powertrain in place. Your Skylark has multiple mounts, including at least one for the transmission.
