Is a Transmission Filter Replacement for You? A Critical Guide for Highlander Owners
When servicing your 2015-2022 Toyota Highlander's transmission, the most important thing to know is which transmission your vehicle has. The service procedure and the need for a filter kit are completely different depending on the model year.
Generation & Transmission Breakdown
- 2015-2016 Highlander (V6): These models are equipped with a 6-speed automatic transmission (U660E). The transmission filter is a serviceable part. It is located inside the transmission oil pan and is meant to be replaced during a fluid service. 🎬 Watch: Step-by-step 6-speed transmission filter change and flush guide.
- 2017-2022 Highlander (V6): These models use a newer 8-speed automatic transmission (UA80E/F). On these transmissions, the filter is an internal component and is NOT considered a standard service item. It can only be accessed by completely disassembling the transmission and is typically only replaced during a major overhaul or rebuild. For these models, a routine service is a "drain and fill" of the fluid only. 🎬 See how to perform a professional 8-speed transmission service.
Pro Tip: If you own a 2017-2022 Highlander, you might see aftermarket filter kits for sale. These are intended for transmission repair shops doing a full rebuild, not for a standard service. Performing a regular drain-and-fill of your transmission fluid every 60,000 miles is the recommended service.
Symptoms of a Clogged Transmission Filter (Mainly for 6-Speed Models)
A clogged filter starves the transmission of fluid, leading to serious problems. If you experience these symptoms, park the vehicle as soon as it is safe to do so.
- Delayed or Harsh Shifting: The vehicle may hesitate or slam into gear.
- Whining or Grinding Noise: A noise from the transmission area that changes with engine RPM can indicate a struggling fluid pump.
- Slipping Gears: The engine may rev up, but the vehicle doesn't accelerate as it should.
- Limp Mode: The vehicle may get stuck in one gear to prevent further damage.
Known Issues for 8-Speed Transmissions (2017-2022)
Many owners of Highlanders with the 8-speed UA80 transmission have reported issues like whining noises, erratic shifting, hesitation, and even premature failure. Toyota has issued Technical Service Bulletins (TSBs) like T-SB-0160-18 and T-SB-0008-21 related to these problems, which in some cases require transmission replacement. 🎬 Watch: Expert breakdown of the 8-speed transmission reliability issues. While a filter change isn't the solution, regular fluid changes may help prolong the life of the transmission.
Choosing the Right Aftermarket Filter Kit (For 6-Speed Models)
While the OEM Toyota filter is the gold standard, several aftermarket brands offer quality alternatives. Here’s a breakdown of common choices:
- OEM (Toyota): The original part is a proven, high-quality strainer designed specifically for your vehicle. You can't go wrong with OEM, but it is the most expensive option.
- Beck Arnley: Often considered a top-tier aftermarket brand, Beck Arnley is known for sourcing parts from OEM manufacturers. This is a trusted choice if you want OEM quality without the dealer price tag.
- Wix: A highly respected name in filtration, Wix makes reliable and well-constructed filters. A solid choice for any owner.
- ATP: A popular value brand, ATP is known for clever features like their "third-hand" gaskets with undersized holes to hold bolts in place during installation, which is very helpful for a DIY job.
- Premium Guard / Vaico: These brands offer a good balance of price and performance for budget-conscious owners. While not as well-known as others, they provide a functional alternative for regular maintenance.

Frequently Asked Questions
Do I need to replace my filter on my 2020 Highlander?
No, if you have the V6 engine, your 2020 Highlander has the 8-speed transmission where the filter is not a serviceable item. The recommended service is a drain-and-fill of the transmission fluid.
Is this a DIY job?
For the 6-speed (2015-2016), it is an intermediate-level DIY job. It requires safely lifting the vehicle, dropping a pan full of fluid (which is messy), and properly torquing the pan bolts. For the 8-speed, a fluid drain-and-fill is simpler but still requires a specific procedure to check the fluid level at the correct temperature.
What is "lifetime" transmission fluid?
Many manufacturers, including Toyota, use this term. However, most mechanics and experienced owners recommend changing the fluid at regular intervals (e.g., every 60,000 miles) to remove contaminants and ensure a long transmission life, even if the filter isn't being changed.
Are there any recalls for the Highlander transmission filter?
No, there are no active recalls on the transmission filter for the 2015-2022 Toyota Highlander. There are, however, TSBs related to performance issues on the 8-speed transmission.
