Guide to Replacing Automatic Transmission Mounts on a 1998-2002 Honda Accord
Stop the shaking and clunking by choosing the right replacement transmission mount for your 6th generation Accord.
- Symptoms of a bad mount include clunking noises when shifting and heavy vibration at idle.
- This generation Accord is known for premature failure of its hydraulic-filled engine and transmission mounts.
- Aftermarket brands like Anchor and Westar are budget-friendly but may increase vibration and have a shorter lifespan than OEM or premium brands like Beck Arnley.
- Replacing transmission mounts is a manageable DIY task with basic tools, a jack, and jack stands.
Symptoms of a Failing Transmission Mount
When a transmission mount wears out, the rubber cracks or separates, and it can no longer hold the transmission securely. This leads to several noticeable problems. 🎬 Watch this video to see common bad transmission mount symptoms. One of the first signs is an increase in vibrations felt inside the car, especially when idling in gear. You might also hear clunking or banging noises when you shift from park to drive or reverse, or during hard acceleration. This sound is the transmission moving and hitting against other components. In some cases, a completely failed mount can cause the transmission to sag, leading to shifting problems or, in severe cases, damage to other parts like axles and hoses.
Known Issues for 6th Gen Accords
🎬 Learn about the top 5 problems for 6th Gen Accords.The 1998-2002 Accord generation is known for having issues with motor and transmission mounts, which are made of rubber and filled with hydraulic fluid. These mounts can leak, tear, and collapse over time, causing significant engine and transmission movement. While there were no specific recalls for the transmission mounts themselves, there was a recall for a transmission parking pawl issue on some 1998 models (NHTSA Recall No. 98V018) and a warranty extension for transmission problems on 2000-2001 models, highlighting the stress this part of the drivetrain endures.
Choosing the Right Aftermarket Mount
When replacing a transmission mount, you have a choice between OEM (Original Equipment Manufacturer) and aftermarket parts. OEM mounts are known for providing the best fit and vibration absorption, but they are also the most expensive. Aftermarket mounts offer a more budget-friendly solution, but quality can vary significantly between brands.
Aftermarket Brand Tiers
- Better Quality (Often OEM-spec): Beck Arnley is often considered a higher-quality aftermarket option, frequently designed to match original factory specifications for fit and performance, which is important for import vehicles like Honda. They are a good choice if you want something close to OEM without the high price tag.
- Standard/Economy: Brands like Anchor, Westar, and DEA are widely available and very affordable. However, owner experiences are mixed. Some find they fit and work fine for daily driving, while others report issues with premature failure, incorrect fitment, and increased cabin vibration compared to the original parts. These are best considered a budget-friendly, but potentially shorter-term, solution.
- Other Options: Pioneer Cable is another available brand, often grouped with the economy tier.
Pro Tip: Many experienced Honda owners recommend using OEM mounts for longevity and to avoid harshness, even if it means buying a good-condition used one. If you choose an aftermarket mount and experience excess vibration, it's likely due to a harder rubber compound than the original.

Frequently Asked Questions (FAQ)
How many transmission mounts does my 1998-2002 Accord have?
The automatic transmission models typically have two transmission mounts, often referred to as a front and a rear transmission mount (located on the driver's side of the engine bay). These work together with the engine mounts to secure the entire powertrain.
Can I replace just one broken mount?
Yes, you can replace just the one that has failed. However, mounts tend to wear out at a similar rate. If one has failed, the others are likely worn and under extra stress. It's often recommended to replace them in pairs or as a set for the best long-term results.
Is this a difficult DIY job? 🎬 Follow this step-by-step guide to replace your Accord's mounts.
For a person with some mechanical experience, this is a very feasible DIY job. It requires safely jacking up the car, supporting the transmission with a floor jack and a block of wood, and using basic hand tools like ratchets and sockets (typically 14mm and 17mm). The rear mount can be more difficult to access than the front one.
How long do aftermarket transmission mounts last?
Lifespan varies greatly. A higher-quality aftermarket mount from a brand like Beck Arnley might last for many years, while economy brands like Anchor or Westar may fail in as little as one to two years, according to some owner reports. Original factory mounts typically last the longest, often over 100,000 miles.
