Automatic Transmission Mount Guide for the 1994-1996 Chevrolet Caprice
Experiencing clunks and vibrations? Your Caprice's transmission mount might be the culprit—but first, let's make sure you have the right model year.
- Verify your vehicle's year; the Caprice was not sold to the public in the US from 1997-2010. You likely have a 1994-1996 model.
- Symptoms of failure include clunking noises on acceleration and excessive vibration at idle.
- For most owners, a standard aftermarket rubber mount offers the best balance of price and ride quality.
- It is recommended to replace the transmission mount at the same time as the engine mounts.
Important: Is Your Caprice a 1998-2002 Model?
Before you shop for parts, it's crucial to confirm your vehicle's year. General Motors did not sell the Chevrolet Caprice to the public in North America between 1997 and 2010. If your Caprice is from this period, it is likely a model produced for the Middle Eastern market, and parts for North American vehicles will not fit. Most owners in the US looking for parts for this body style actually have a 1994, 1995, or 1996 Caprice. This guide focuses on these correct North American models.
Symptoms of a Failing Transmission Mount
When the transmission mount on a 1994-1996 Caprice wears out, the signs are usually obvious. The rubber cushion degrades over time, allowing for excessive movement. Here’s what to look and listen for:
- Clunking or Banging Noises: This is the most common symptom. You may hear a loud clunk when you shift from Park into Drive or Reverse, or during hard acceleration. This is the sound of the transmission lifting and hitting the car's frame.
- Excessive Vibrations: A new or worsening vibration felt in the steering wheel, floor, or seats, especially when idling in gear, points to a worn mount. The mount is no longer absorbing the normal vibrations from the engine and transmission.
- Visible Engine and Transmission Movement: With the hood open and the parking brake set, have a helper briefly rev the engine while in Drive (with their foot firmly on the brake). If you see the engine and transmission assembly rock or lift significantly, the mount has failed.
Choosing the Right Aftermarket Mount
For the 1994-1996 Caprice, you have two main choices for aftermarket transmission mounts: standard rubber or performance polyurethane.
Standard Rubber Mounts (Good for Most Owners)
A standard rubber mount is designed to be like the original part. It provides a good balance of durability and vibration absorption for a comfortable ride. These are the most affordable and are perfect for a daily driven vehicle.
- Brands: Anchor, DEA, Westar, Duralast
- Quality: These are economy brands that meet basic requirements. They are a cost-effective solution, though they may not last as long as an original GM part. For a vehicle of this age, they offer a good value.
Polyurethane Mounts (For Performance Use)
Polyurethane is a much stiffer material than rubber. It is highly durable and resistant to oil and chemicals. A polyurethane mount will drastically reduce transmission movement, which can improve throttle response. However, it will also transfer significantly more vibration and noise into the cabin. This is a good option for a modified or performance-oriented car, but not recommended if you want a smooth, quiet ride.
- Brands: Prothane, Energy Suspension
- Quality: These are well-regarded performance brands. They are designed for durability under stress, but the trade-off is always increased noise, vibration, and harshness (NVH).
Pro Tip: It is highly recommended to replace the transmission mount any time you are replacing the two main engine mounts. If the engine mounts have failed, the old transmission mount has been under extra stress and is likely worn as well.
Known Issues, Recalls, or TSBs
Searches of the National Highway Traffic Safety Administration (NHTSA) database and for Technical Service Bulletins (TSBs) did not show any specific recalls or service bulletins related to the automatic transmission mount for the 1994-1996 Chevrolet Caprice. Recalls found for the "Caprice" nameplate are for later, police-only vehicles and concern the shift lever, not the mount itself.

Frequently Asked Questions
Is it difficult to replace the transmission mount myself?
For an experienced DIY mechanic, this is a relatively simple job. It requires a good floor jack, jack stands, and basic hand tools. The transmission must be supported with the jack, the crossmember unbolted, the old mount swapped out, and everything reassembled. It can typically be done in about 1 to 2 hours.
Is the transmission mount the same as the crossmember?
No. The transmission mount is the rubber and steel part that bolts to both the transmission and the crossmember. The crossmember is the large metal bar that spans the frame rails underneath the transmission. The mount bolts to the crossmember to support the transmission.
Should I use an OEM GM part?
Finding a new OEM GM part for a 1994-1996 Caprice can be difficult and expensive. Given the age of the vehicle, a quality aftermarket rubber mount from a brand like Anchor or Duralast is a perfectly acceptable and much more affordable choice for a daily driver.
Can a bad transmission mount cause shifting problems?
Yes, in some cases. If the mount is completely broken, the resulting misalignment of the transmission can sometimes affect the shifter linkage, making it difficult to shift gears. It can also lead to damage to driveshaft U-joints if left unfixed for a long time.
Technical Specifications
The 1994-1996 Caprice uses a single, rear transmission mount that bolts to a removable crossmember. It is a non-hydraulic, rubber and steel design. Aftermarket polyurethane options are available.
