Dodge Grand Caravan Automatic Transmission Mount Guide: 1990-1995
If you hear a loud clunk when shifting your Grand Caravan into gear, a bad transmission mount is the likely cause.
- A loud clunk when shifting into gear is the number one sign of a failed transmission mount on this van.
- Budget aftermarket brands like Anchor, DEA, and Westar are affordable but may increase vibration and not last as long as the original part.
- It is highly recommended to inspect all engine and transmission mounts and replace them as a set for a complete repair.
- You can drive with a bad mount, but you should get it fixed soon to prevent damage to other components like axles and hoses.
Is Your Grand Caravan Making Noises and Vibrating?
A worn-out automatic transmission mount is a very common issue on first-generation Dodge Grand Caravans. Over decades of use, the rubber inside the mount cracks, gets soaked with oil, or simply collapses from the weight of the transmission. When this happens, it can no longer support the transmission properly. This allows the whole engine and transmission assembly to move and shake, causing noises and vibrations inside the van. Ignoring a bad mount can lead to more stress and damage on other parts like CV axles, engine mounts, and exhaust pipes.
Symptoms of a Failing Transmission Mount
When a transmission mount fails, the signs are usually obvious. Look for one or more of the following symptoms:
- Loud Clunking Noise: This is the most common sign. You will hear a loud "clunk" or "bang" from the engine bay when you shift from Park into Drive or Reverse. You may also hear it when you accelerate hard or brake suddenly.
- Excessive Vibration: You may feel a new, strong vibration through the steering wheel, floor, or seats. This is often worst when the van is stopped at a light but still in gear.
- Visible Engine Movement: You can often see the problem. With the parking brake set and a helper's foot firmly on the brake pedal, watch the engine as they shift from Drive to Reverse. If the engine assembly rocks or lurches more than an inch, a mount has failed.
Known Issue: 1992 Model Year
A factory recall was issued for some 1992 models concerning the transmission mounting boss. This is the threaded part on the transmission case itself where the mount bolts on. While rare, be aware of this potential issue during inspection.
Choosing the Right Aftermarket Mount
Since original Mopar parts for this van are generally no longer available, you will be choosing from aftermarket brands. The brands you will commonly find are budget-friendly, but quality can vary.
- Standard/Economy Tier (Anchor, DEA, Westar): These brands offer the most affordable replacements. They will secure your transmission, but be aware that many owners report they use a harder rubber compound. This can cause more cabin vibration than the original part. Their lifespan can also be shorter than an OEM part. They are a functional, low-cost solution.
- Standard/Mid-Grade Tier (Pioneer): Some mechanics and users have noted that Pioneer brand mounts can be a step up in quality, sometimes looking and feeling closer to the original factory mounts. While still an affordable aftermarket brand, they may offer a better balance of price and performance.
Pro Tip: Replace Mounts as a Set
Your Grand Caravan has multiple mounts holding the engine and transmission. If the transmission mount has failed, the other mounts (for the engine) are the same age and have been under extra stress. It is highly recommended to inspect all of them and replace them as a set for the best, longest-lasting repair.

Cost estimates are based on national averages and may vary by location and repair shop.
Frequently Asked Questions (FAQ)
Can I drive with a bad transmission mount?
Yes, but it's not recommended for long. The vehicle will still drive, but the excessive movement can damage other expensive parts like axles, wiring, and hoses over time. It's best to get it replaced as soon as you can.
How hard is it to replace the transmission mount myself?
For a DIYer with basic tools, this is a manageable job. It involves supporting the transmission with a jack and wood block, removing the battery and battery tray for access, and unbolting the old mount. It typically takes 1-2 hours.
Will a new aftermarket mount make my van vibrate more?
It might. Cheaper aftermarket mounts often use solid, harder rubber instead of the softer or hydraulic design of the original. This can transmit more of the engine's natural vibration into the cabin, especially when idling in gear.
How do I know for sure the transmission mount is the problem?
The visual test is the most reliable. Have a helper safely shift the van between Drive and Reverse while you watch the engine with the hood open (and your feet on the brakes). If you see the engine assembly lurching or rocking significantly, a mount is broken. A mechanic can also put the van on a lift to check for cracks or collapsed rubber.
Technical Specifications
The automatic transmission mount for this generation is typically a non-hydraulic, solid rubber and steel design located on the driver's side of the engine bay.
