The 2013 Highlander requires Toyota ATF WS (World Standard) automatic transmission fluid.
What is ATF WS and why it matters
ATF WS stands for World Standard automatic transmission fluid. Toyota developed WS to improve performance, oxidation resistance, and compatibility with newer automatic transmissions. The 2013 Highlander, with its two gasoline engine options, uses automatic transmissions that call for ATF WS to ensure smooth shifting and proper lubrication.
Recommended fluids for the 2013 Highlander
To help you shop, here are fluids that meet Toyota’s official specification for this vehicle:
- Toyota ATF WS (World Standard) – the OEM fluid for Highlander transmissions
- Aftermarket ATF that explicitly meets Toyota WS specification
- Note: Do not substitute with older Dexron III/Mercon or other non-WS fluids unless a dealer has confirmed compatibility
When replacing, use the exact WS specification recommended by Toyota to avoid shifting problems or wear. If you’re unsure, visit a dealership or trusted mechanic for a fluid change.
Maintenance tips: checking and changing ATF
These tips cover general checks and changes. Always follow your owner’s manual for the exact procedure and fluid capacity. Some Highlander models built around this era may not have a traditional transmission dipstick, which can affect how you check the fluid level.
Dipstick availability
Many modern Toyota transmissions are designed without a manual dipstick. If your Highlander lacks a dipstick, use the service interval and recommended fill procedure from Toyota, or have a professional perform level checks and top-offs.
Below are general steps for checking and replacing ATF in a modern automatic transmission, but always follow the service manual for your specific model. The Highlander may not have a traditional dipstick on some transmissions, so service procedures can vary.
- Warm up the engine and transmission to normal operating temperature.
- Park on level ground and engage the parking brake (and wheel chocks if needed).
- Check whether your transmission has a dipstick. If so, pull it out, wipe, reinsert, and check fluid level as per the manual.
- If performing a fluid change, drain the old fluid from the pan (and any drain plug) or follow the manufacturer’s recommended procedure for fluid exchange.
- Refill with the recommended ATF WS fluid to the correct level, as indicated by the dipstick or service procedure.
- Cycle through gears with the engine running (with brakes applied) to circulate fresh fluid, then recheck level once the vehicle is cooled.
Carefully follow the detailed service steps in the owner’s manual or a Toyota service guide. If you’re not comfortable, have a professional perform the fluid change to avoid air pockets or improper filling.
Summary
For a 2013 Toyota Highlander, the correct transmission fluid is Toyota ATF WS (World Standard). Always verify the spec in your owner's manual, and when in doubt, consult a Toyota dealer or trained technician to ensure you use the right fluid and follow the proper service procedure.
