Is Your Acura TL Making a Gurgling Noise?
If you own a 2007-2014 Acura TL, you might be familiar with transmission concerns. A common symptom of a problem is a gurgling or chirping sound from under the hood when you first start the car, especially when it's cold. This specific noise was addressed by Acura in a Technical Service Bulletin (TSB #10110849), which identified the cause as a restriction in the automatic transmission fluid 🎬 See how to fix that cold start gurgling noise here (ATF) filter. This is a clear sign that your filter is clogged and needs to be replaced.
Symptoms of a Clogged Transmission Filter
Besides the gurgling noise, other signs point to a filter that needs changing:
- Rough or Delayed Shifting: The car may hesitate or jerk when shifting between gears, especially at low speeds.
- Whining or Grinding Sounds: Noises from the transmission area that change with engine speed can indicate fluid is struggling to get through the filter.
- Slipping Gears: The engine may rev higher than usual without an increase in speed, as if the transmission is not fully engaged.
- Transmission-Related Warning Lights: A clogged filter can contribute to issues that trigger the check engine light.
OEM vs. Aftermarket Filters
For many parts, the debate between Original Equipment Manufacturer (OEM) and aftermarket is complex. For the Acura TL's external transmission filter, the choice is more straightforward. The OEM filter (part number 25430-PLR-003) is a high-quality, reliable option that many owners prefer for peace of mind.
However, since this is a simple cartridge filter, high-quality aftermarket brands are also a viable choice and can offer cost savings. Look for brands known for their filter quality.
- Premium Aftermarket (Wix, Vaico): These brands generally have a strong reputation for meeting or exceeding OEM specifications. Vaico, for example, markets itself as an OE-quality supplier. WIX is a well-respected name in filtration. These are excellent alternatives to OEM.
- Standard Aftermarket (ATP, Premium Guard): These are often more budget-friendly options. While they are designed to fit and function, they may not use the same quality of filter media or gaskets as premium brands or OEM. They can be a good choice for those on a tight budget who adhere to frequent service intervals.

| New Aftermarket Filter Kit | $11 - $92 |
| Shop Labor for Installation | $100 - $225 |
Pro Tip: Always Use the Right Fluid
Acura transmissions are very sensitive to the type of fluid used. When you or a shop perform this service, you must use genuine Acura/Honda ATF DW-1 transmission fluid. Using a generic or multi-vehicle fluid can lead to poor shifting, torque converter shudder, and even premature transmission failure.
Frequently Asked Questions (FAQ)
How often should I change my Acura TL's transmission filter?
While Acura's maintenance schedule focuses on fluid changes every 30,000 to 60,000 miles, it's a good practice to replace this external filter at the same time or at least every 60,000 miles. 🎬 Watch: Maintenance walkthrough for 2004-2008 Acura TL models Given the low cost of the part and the known issues with clogging, proactive replacement is wise.
Is this the only transmission filter in my car?
No. There is a second, internal filter (often called a strainer) located inside the transmission pan. However, this filter is not considered a regular service item and is typically only replaced during a complete transmission rebuild. The kit you are buying is for the easily accessible external filter.
Can I replace the filter myself?
Yes, this is a very DIY-friendly job for someone with basic tools. The filter is located under the air intake box in the engine bay. The process involves removing the airbox, unbolting the filter housing, and swapping the old cartridge for the new one. The entire job usually takes about an hour.

You don't have to drain all the fluid, but a small amount will spill when you open the filter housing. It is highly recommended to perform a transmission fluid drain-and-fill at the same time you change the filter. This ensures the entire system has fresh, clean fluid.
