A Guide to the Automatic Transmission Mount for the 2009-2013 Honda Accord
If your Accord is vibrating or making clunking noises when you shift, a bad transmission mount could be the problem.
- The most common signs of failure are new vibrations and clunking noises when shifting gears.
- Your Accord has multiple mounts; it's best to inspect all of them, as one failure puts stress on the others.
- Aftermarket brands like Anchor and Westar are affordable, but premium brands like Beck Arnley or OEM will likely provide better vibration damping and longevity.
- Replacement is a manageable DIY job for those with the right tools, but shop labor is relatively inexpensive for this task.
Is Your Accord Shaking? Signs of a Failing Transmission Mount
When a transmission mount wears out, the rubber cracks or collapses, and it can no longer do its job. This leads to several common symptoms. You are the best judge of how your car normally feels, so pay attention to any new or unusual signs.
🎬 Watch: 7 common signs of a bad transmission mount- Excessive Vibrations: This is the most common sign. You might feel a new, strong vibration through the steering wheel, the floor, or your seat, especially when accelerating or when the car is stopped in gear.
- Clunking or Banging Noises: Loud clunks, bangs, or thuds when you shift from Park to Drive, Drive to Reverse, or during hard acceleration are a red flag. This noise is the transmission moving around and hitting other parts because the mount is no longer holding it tightly.
- Excessive Engine Movement: A worn mount allows the entire engine and transmission assembly to rock back and forth more than it should. A mechanic can often spot this by watching the engine while shifting gears with the brakes applied.
- Rough Shifting: In some cases, a bad mount can cause the transmission to sit at the wrong angle. This misalignment can make gear shifts feel harsh or difficult. 🎬 Watch this guide to fixing hard shifts with a new mount
Known Issues for the 2009-2013 Accord
While there are no specific recalls or Technical Service Bulletins (TSBs) for the transmission mounts on this generation of Accord, there is a recall for certain 2013 models. NHTSA recall 25V422 affects 2013 Accords with the 4-cylinder engine and CVT transmission sold in states that use road salt. The recall addresses driveshafts that can corrode and break, which is a separate issue from the mounts but can also cause vibrations or loss of power. It is always a good idea to check if your vehicle is affected by any open recalls.
Choosing the Right Aftermarket Transmission Mount
When replacing your transmission mount, you have a choice between Original Equipment (OEM) and aftermarket parts. For a high-wear part like a mount, quality matters. Aftermarket brands for your Accord generally fall into different quality tiers.
Good Tier: Beck Arnley
Beck Arnley is often considered a higher-quality aftermarket brand. They are known for focusing on parts that match the original fit, form, and function. Forum discussions sometimes suggest that Beck Arnley may even be the original equipment supplier for some parts, making them a solid choice if you want quality close to OEM without the dealer price tag.
Standard Tier: Anchor, DEA, Westar
Brands like Anchor, DEA, and Westar are widely available and offer a balance of affordability and function. They are a practical choice for daily drivers, especially on an older, higher-mileage Accord. While generally considered budget-friendly, some users have reported that the rubber can be harder, leading to slightly more vibration than an OEM part, or that the metal components may not be as thick as the original. However, for the price, they are a very common repair choice.
Pro Tip: Replace Mounts in Sets
Your Accord has multiple engine and transmission mounts (typically five in total for the 2.4L engine). When one mount fails, it puts extra stress on the others, causing them to wear out faster. If you replace only one failed mount, you may find yourself doing the same job for a different mount soon after. For the best results, inspect all mounts and consider replacing them as a set.

Frequently Asked Questions
How many transmission mounts does my Accord have?
The 2009-2013 Honda Accord with the 2.4L automatic transmission has a total of five mounts that secure the engine and transmission. This includes an upper and a lower transmission mount, along with three engine mounts. They all work together as a system.
Can I replace a transmission mount myself?
Yes, this is a DIY-feasible job for someone with mechanical experience and the right tools. The process involves safely supporting the transmission from below with a jack and a block of wood, unbolting the old mount, and installing the new one. It can be challenging to get everything aligned, and you must work safely. If you are not comfortable, it is a relatively quick job for a professional mechanic.
What is the difference between an engine mount and a transmission mount?
They perform the same function but are located in different positions. The engine and transmission are bolted together, and this entire assembly is held in place by several mounts. The mounts on the engine side are called engine mounts, and the ones on the transmission side are called transmission mounts.
Will a cheap aftermarket mount work?
Cheaper aftermarket mounts from brands like Anchor or DEA will work, but they may not last as long or absorb vibrations as effectively as an OEM or premium aftermarket part like Beck Arnley. For an older vehicle or if you are on a tight budget, they are a reasonable option, but be aware of the potential trade-off in ride quality and longevity.
