Lexus ES350 Automatic Transmission Mount Guide (2020-2025)
Experiencing clunks or vibrations in your Lexus ES350? Your transmission mount might be the cause.
- Failure on the 2020-2025 ES350 is uncommon, but symptoms include clunking noises and new vibrations.
- There are no active recalls or TSBs for this specific part on this model range.
- Replacement is a labor-intensive and expensive job, likely requiring professional installation.
- Aftermarket brands like Anchor offer a cost-saving, but may not provide the identical ride quality and longevity of an OEM part.
Is Your Lexus ES350 Shaking or Making Clunking Noises?
A failing automatic transmission mount can disrupt the smooth and quiet ride of your 2020-2025 Lexus ES350. Because these vehicles are relatively new, mount failure is not common, but it can happen. When the rubber in the mount wears out or breaks, it can no longer hold the transmission securely or absorb vibrations. This leads to several noticeable symptoms.
Symptoms of a Bad Transmission Mount
- Excessive Vibration: You may feel a new, persistent vibration through the floor, seats, or steering wheel, especially when the car is in gear and stopped at a light.
- Clunking or Thumping Noises: A distinct “clunk” or “thump” sound when you shift from Park into Drive or Reverse is a classic sign. You might also hear this noise during hard acceleration or braking as the transmission shifts its weight.
- Impact Sensations: The car may feel like it's jerking or lurching when you accelerate or shift gears, indicating excessive movement in the drivetrain.
Known Issues & Recalls
As of early 2026, there are no specific recalls or widespread technical service bulletins (TSBs) from Lexus or the NHTSA for automatic transmission mount failure on the 2020-2025 ES350. Any failure is typically due to individual circumstances rather than a manufacturing defect.
Choosing a New Aftermarket Transmission Mount
When replacing the transmission mount on your ES350, you have two main choices: Original Equipment Manufacturer (OEM) or aftermarket. For a luxury vehicle, the choice impacts ride quality.
- OEM Mounts: Made by Lexus (or their supplier), these parts are identical to the one installed at the factory. They guarantee the same fit, performance, and vibration-damping characteristics your car was designed to have. The downside is a significantly higher cost.
- Aftermarket Mounts (Anchor): Brands like Anchor provide a more affordable alternative. They are designed to meet OE standards for fit and function. However, user reviews for budget-friendly aftermarket mounts sometimes report they use harder rubber compounds. This can result in a shorter lifespan or a slight increase in cabin vibration compared to the original OEM part. For a daily driver where cost is a major factor, an aftermarket part is a viable option. If preserving the original Lexus ride feel is your top priority, OEM is often the preferred choice.
A Note on Replacement Complexity
Replacing the transmission mount on a 2020-2025 ES350 can be a complex job. Some repair estimates indicate very high labor costs, which suggests that accessing the mount may require removing other major components like the subframe. This is not typically a simple bolt-off, bolt-on job for a beginner.
Cost of Replacing a 2020-2025 ES350 Transmission Mount

Frequently Asked Questions
Why is the replacement cost so high for my 2020-2025 ES350?
Repair data for the 2020-2025 ES350 indicates that replacing the transmission mount is a labor-intensive process. The high cost is primarily due to the time required to access the mount, which may involve supporting the engine and removing parts of the vehicle's subframe.
Can I drive with a bad transmission mount?
You can drive the vehicle, but it is not recommended for an extended period. A completely failed mount can put extra stress on other components like engine mounts, CV axles, and exhaust connections, leading to more expensive repairs down the road.
How long should a transmission mount last?
Original transmission mounts on a normally driven vehicle are expected to last 100,000 miles or more. Factors like rough road conditions, aggressive driving, or fluid leaks can cause them to wear out sooner.
Will a bad transmission mount cause a Check Engine Light?
In some cases, yes. If the transmission moves excessively, it can put stress on wiring harnesses or sensors. The severe vibration itself can sometimes be detected by the vehicle's computer, potentially triggering a Check Engine Light.
Technical Specifications
The automatic transmission mount for the Lexus ES350 is a metal and rubber assembly designed to support the transmission and dampen vibrations. Some original mounts may be hydraulic (fluid-filled) to provide superior vibration absorption.
