Nissan Frontier Automatic Transmission Mount: A Complete Guide (2010-2025)
If you're feeling new vibrations or hearing clunks when you shift, your Frontier's transmission mount might be the culprit.
- The most common signs of failure are new vibrations at idle and clunking noises when shifting gears.
- OEM mounts offer the best durability and ride quality, while brands like Anchor, DEA, and Westar are budget-friendly alternatives that may compromise on longevity.
- Fitment is different between the 2010-2019 and 2020-2025 model years; you must verify the part matches your truck's year and engine.
- While driving is possible, it should be limited as a bad mount puts extra stress on other parts like hoses, exhaust, and driveshaft joints.
Is Your Frontier's Transmission Mount Failing?
A transmission mount is a wear-and-tear item. The rubber inside it can dry out, crack, or collapse from age, heat, and stress. When it fails, you'll notice it. The most common signs are new or excessive vibrations felt through the floor and seats at idle or while driving, and loud clunking noises when you shift from park to drive or reverse.
Symptoms of a Bad Transmission Mount
- Excessive Vibration: A new, strong vibration felt in the cabin, especially when the truck is in gear and stopped, is a primary symptom.
- Clunking or Thudding Noises: You may hear a distinct 'clunk' or 'bang' when you accelerate, brake hard, or shift gears. This is the sound of the transmission moving too much and hitting against its stops. 🎬 Watch: How to diagnose a bad mount for good.
- Rough Shifting: As the mount wears, it can cause the transmission to become misaligned, leading to jerky or difficult gear changes.
- Visible Movement: If you can safely have a helper watch the engine bay while you shift from drive to reverse (with your foot firmly on the brake), they may see the engine and transmission assembly rock or lurch excessively.
Important: Check Your Model Year Before Ordering
The 2010-2025 Nissan Frontier spans two different generations. The transmission mount is NOT the same for all years. The introduction of the 3.8L V6 engine and 9-speed transmission in 2020 marked a change.
• 2010-2019 models (with 4.0L V6 or 2.5L I4) use one type of mount.
• 2020-2025 models (with 3.8L V6) use a different mount.
Always verify the part fits your specific year and engine before purchasing.
Choosing the Right Aftermarket Mount: OEM vs. Aftermarket Brands
When replacing your Frontier's transmission mount, you have a choice between Original Equipment (OEM) and aftermarket parts. Your choice depends on your budget and priorities.
- OEM (Original Equipment Manufacturer): This is the same part Nissan installed at the factory. It guarantees a perfect fit, original ride quality, and the longest lifespan. The main drawback is the higher cost.
- Aftermarket (Anchor, DEA, Westar): These brands offer a much more affordable solution. However, they are generally considered economy-tier options. While they will function, some owners in various forums report that these brands may not absorb vibrations as effectively as OEM parts and may have a shorter service life. For a truck you plan to keep long-term, investing in an OEM mount is often recommended for the best performance. If you're on a tight budget, an aftermarket mount will get the job done.
Pro Tip: Inspect While You're There
The transmission mount is just one of three main mounts supporting your drivetrain. If your transmission mount has failed due to age and mileage, your two engine mounts are likely worn as well. It's a good idea to inspect them at the same time. Replacing all three can restore your truck's smoothness and prevent future repairs.

Frequently Asked Questions (FAQ)
Is there a recall on the Frontier transmission mount?
No, there are no specific recalls for the transmission mount itself. However, there is a significant recall (NHTSA ID: 22V457000) for the parking pawl inside the transmission on 2020-2022 models, which can cause a rollaway risk. The official Nissan procedure to fix this recall involves removing and reinstalling the transmission mount, so it is a related component.
🎬 Watch: Details on the 2020-2022 Frontier parking pawl recall.Can I replace a transmission mount myself?
Yes, this is a feasible DIY job for someone with moderate mechanical skills and the right tools. The key is to safely support the weight of the transmission with a floor jack and a block of wood before unbolting the old mount. The job typically involves removing a few bolts on the crossmember and two bolts on the transmission itself.
How long does it take to replace a transmission mount?
An experienced DIYer can typically complete this job in 1 to 2 hours. A professional shop can often do it in about an hour of labor time.
Could my 'clunking' noise be something else?
Yes. While a bad mount is a common cause, some 2020-2021 Frontiers with the 9-speed transmission have been subject to complaints and a class-action lawsuit regarding clunking noises and erratic shifting that are internal to the transmission. If your mount appears to be in good condition, further diagnosis may be needed.
