A Deep Dive into the 2018-2024 Jeep Wrangler Automatic Transmission Mount
Understanding when and why you might need to replace this critical part on your JL Wrangler.
- For any Wrangler used off-road, OEM Mopar mounts are strongly recommended for durability.
- Budget aftermarket brands like Anchor and DEA are suitable for light-duty, on-road use only.
- Symptoms like clunking and vibration can also be caused by loose mounting bolts; check these first.
- Replacing a bad mount promptly prevents costly damage to other drivetrain components.
Is Your Wrangler's Transmission Mount Failing?
A failing transmission mount can be mistaken for a more serious transmission problem. Because the part is designed to absorb vibration and secure the drivetrain, the symptoms of failure are usually noticeable. If you experience any of the following, it might be time to inspect your transmission mount.
🎬 Watch: 5 signs your transmission mount is failingKey Symptoms of a Bad Mount:
- Excessive Vibrations: You might feel a new or unusual vibration through the floor, seat, or steering wheel, especially during acceleration.
- Clunking or Banging Noises: Loud clunks when you shift from Park to Drive or Reverse, or during acceleration, can be a sign. This is the sound of the transmission moving excessively and hitting other components.
- Engine and Transmission Movement: A worn mount can allow the entire engine and transmission assembly to move or lurch, especially under torque. You can sometimes see this by having a helper put the vehicle in gear while you watch the engine bay (with the parking brake firmly set).
Choosing the Right Aftermarket Mount for Your Wrangler
When replacing your transmission mount, you have a choice between the original equipment (OEM) part from Mopar and various aftermarket brands. For the 2018-2024 Wrangler, common aftermarket options include brands like Anchor and DEA. Here’s how to decide.
Brand Quality Tiers
- OEM (Mopar): This is the highest quality and most expensive option. It's designed specifically for your vehicle and will restore the original ride quality and durability. If you frequently take your Wrangler off-road or want the longest-lasting repair, OEM is the recommended choice.
- Standard Aftermarket (Anchor, DEA): These brands offer a significant cost saving. However, general owner feedback across many vehicle types suggests these mounts may not last as long or absorb vibrations as effectively as OEM. For a Wrangler used only for daily commuting on paved roads, these can be a viable budget option. However, the harder rubber sometimes used can increase cabin vibration. 🎬 Watch: How a damaged mount causes excessive engine vibration

Frequently Asked Questions
Is a bad transmission mount a serious problem?
It should be addressed as soon as possible. While the vehicle is usually drivable, a broken mount puts extra stress on your engine mounts, driveshaft, CV joints, and exhaust system, potentially leading to more expensive repairs down the line.
Are there any recalls for the JL Wrangler transmission mount?
No, there are no specific recalls for the automatic transmission mount itself. There was a recall for some 2018 Wranglers for an incorrect transmission park lock rod, but this is an internal transmission part. A separate recall on manual transmission clutches required removing the transmission mount, and some owners have reported issues with bolts not being properly reinstalled by the dealer afterward.
Can I replace the transmission mount myself?
Yes, this is a feasible DIY project for someone with the right tools and mechanical experience. The job requires safely lifting and supporting the vehicle, then using a jack to support the transmission while you unbolt and replace the mount and crossmember. It typically takes 1-2 hours.

For most owners, the answer is no. Polyurethane mounts are very stiff and designed for racing. While durable, they will transfer significantly more vibration and noise into the cabin, making for a harsh ride in a daily-driven or off-road Wrangler. It's best to stick with a quality rubber mount.
