Transmission Fluid for 2020 Toyota Highlander

Recommended Transmission Fluid

For the 2020 Toyota Highlander, the manufacturer recommends using Toyota Genuine ATF WS (Automatic Transmission Fluid World Standard). This fluid is specifically designed for Toyota vehicles and ensures optimal performance and longevity of the transmission.

Tools Required

Transmission Fluid Dipstick (if applicable)
Fluid Pump (for easier fluid transfer)
Suction Gun (optional, for fluid removal)
Container (for old fluid disposal)
Funnel (for adding new fluid)
Socket Set (for transmission pan removal, if necessary)
Torque Wrench (for re-installing bolts)

Repair Instructions

Step 1: Prepare the Vehicle

Park on Level Ground: Ensure the vehicle is on a flat surface for accurate fluid level readings.
Engine Warm-Up: Start the engine and let it warm up to operating temperature. This ensures the fluid is at the correct viscosity for checking levels.

Step 2: Check Fluid Level

Locate the Dipstick: If applicable, locate the transmission dipstick (usually marked with a bright color).
Remove and Inspect: Pull out the dipstick, wipe it clean, and reinsert it. Remove again to check the fluid level.
- Correct Level: Fluid should be between the "Full" and "Add" marks.
- Fluid Condition: Check for burnt smell or dark color; if so, a fluid change is needed.

Step 3: Drain Old Fluid (if necessary)

Raise the Vehicle: Use jack stands to lift the vehicle securely.
Locate the Drain Plug: Find the transmission drain plug on the transmission pan.
Drain Fluid: Use a socket to remove the drain plug and let the old fluid drain into a container.

Step 4: Replace Fluid

Replace the Drain Plug: Reinstall and torque the drain plug to the manufacturer specifications.
Add New Fluid: Use a funnel to pour Toyota Genuine ATF WS through the dipstick tube or transmission fill port until it reaches the full mark.
- Volume: Typically, it requires about 5 to 7 quarts, but refer to the owner’s manual for exact specifications.

Step 5: Check for Leaks

Start the Engine: Let the vehicle run for a few minutes and shift through all the gears.
Recheck Fluid Level: After cycling through the gears, check the fluid level again and add as necessary.
Inspect for Leaks: Check under the vehicle to ensure there are no leaks around the pan or fill port.

Step 6: Final Steps

Dispose of Old Fluid: Properly dispose of the old transmission fluid according to local regulations.
Lower Vehicle: Carefully lower the vehicle back to the ground.
Test Drive: Take the vehicle for a short test drive to ensure proper transmission operation.

By following these steps, you can ensure that your 2020 Toyota Highlander is using the correct transmission fluid and operating efficiently. If issues persist, consider consulting a professional technician for further diagnosis.
