A Volkswagen Passat Owner's Guide to the Automatic Transmission Mount (2012-2022)
Feeling a clunk or vibration in your Passat? Your transmission mount might be the culprit.
- Listen for clunks on acceleration and feel for vibrations at idle; these are the top signs of a failed mount.
- Be cautious with budget brands like Anchor and DEA, as forums report they can cause vibrations and fail quickly.
- OEM or OEM-quality brands like Febi are strongly recommended for ride quality and longevity.
- Always verify the correct part number with your VIN before ordering, as multiple versions exist.
Is Your Passat's Transmission Mount Failing?
A worn-out transmission mount on a 2012-2022 Volkswagen Passat will make its presence known through distinct sounds and feelings. 🎬 Watch this video on 7 common bad transmission mount symptoms Because this part is made of rubber and metal, it wears out over time from heat and constant flexing. When the rubber cracks or separates, it can no longer do its job of absorbing vibration and securing the transmission.
Common Symptoms:
- Excessive Vibration: You may feel a noticeable vibration through the steering wheel, floor, or seats, especially when the car is idling in gear. Some owners describe it as a general harshness that wasn't there before.
- Clunking or Banging Noises: A loud "clunk" or "bang" when you accelerate, brake hard, or shift from Park into Drive or Reverse is a classic sign. This sound is the transmission itself moving and hitting against the chassis because the mount is no longer holding it firmly.
- Rough Shifting: While not as common, a failing mount can sometimes contribute to jerky or rough gear shifts. The movement of the transmission can affect shift timing and quality.
- Visible Engine Movement: If you have a helper, you can observe the engine while the car is in gear with the brakes held firmly. If you see the engine and transmission assembly lurching forward or backward excessively as the gas is lightly applied, the mounts are likely worn.
No Specific Recalls, But a Known Issue
Searches of the National Highway Traffic Safety Administration (NHTSA) database and for Technical Service Bulletins (TSBs) did not show any specific recalls or service campaigns for the transmission mount on the 2012-2022 Passat. However, premature mount failure is a commonly discussed issue among owners.
Choosing the Right Aftermarket Mount
When shopping for a new aftermarket transmission mount, you'll find a few quality tiers. The choice you make often comes down to budget versus longevity and ride quality.
Budget-Tier Brands (Anchor, DEA)
Brands like Anchor and DEA are widely available and are typically the most affordable option. However, experiences shared by mechanics and vehicle owners in online forums are frequently negative. Many report that these mounts are made from a harder rubber compound that transmits more vibration into the cabin than the original, even when new. There are also numerous accounts of these parts failing in a very short time, sometimes within just a few months. These brands may be a short-term fix if budget is your only concern, but be prepared for potential issues with vibration and a shorter lifespan.
OEM-Quality and OEM Brands
For a part like a mount, where vibration control is key, sticking closer to the original equipment (OEM) design is often the best choice. Brands like Febi or Lemfoerder are often OEM suppliers and provide a part that performs like the original. While the upfront cost is higher than budget brands, they are far less likely to cause vibration issues and are expected to last much longer, saving you from doing the job a second time.
Pro Tip: Verify Your Part Number
Volkswagen used a few different mounts for the 2012-2022 Passat depending on the engine and specific model year. It's common for owners to be confused about which part is correct. Always use your vehicle's VIN to confirm the exact OEM part number (e.g., 1K0199555CE, 1K0199555CK) before ordering an aftermarket cross-reference.
Replacement Cost
The cost to replace the transmission mount can vary significantly based on the parts you choose and whether you do it yourself.

| New Aftermarket Part (Budget) | $50 - $90 |
| New Aftermarket Part (OEM-Quality) | $90 - $150 |

Frequently Asked Questions
Can I replace the Passat transmission mount myself?
Yes, this is a manageable DIY job for someone with the right tools and some mechanical experience. The process involves removing the airbox, battery, and battery tray to access the mount. You must safely support the transmission from underneath with a floor jack and a block of wood before unbolting the old mount. The job typically takes 1.5 to 2.5 hours.
🎬 See this step-by-step VW Passat transmission mount replacement videoHow many transmission mounts does a Passat have?
Your Passat has a system of mounts to hold the powertrain. This includes a passenger-side engine mount, a driver-side transmission mount, and a lower mount often called a "dogbone" mount. The driver-side transmission mount is a common failure point.
🎬 Watch how to replace Passat engine and transmission mountsWhat happens if I don't replace a bad transmission mount?
Ignoring a bad mount can lead to other problems. The constant movement can put stress on other components like CV joints, axles, exhaust pipes, and various hoses and wires connected to the engine. In severe cases, the added stress can cause these other parts to fail, leading to more expensive repairs.
Why do cheap aftermarket mounts cause more vibration?
The primary job of the mount's rubber is to absorb vibration. To cut costs, budget manufacturers often use a solid, harder rubber compound that is less effective at damping vibrations compared to the softer, sometimes fluid-filled, design of the OEM part. This results in more of the engine's natural vibration being transferred to the car's frame, which you feel in the cabin.
