Repair Instructions

Step 1: Checking the Transmission Fluid Level

Warm Up the Engine:
- Start the vehicle and allow it to reach operating temperature.
Park on Level Ground:
- Ensure the vehicle is on a level surface and put it in "Park" (P).
Locate the Dipstick:
- If applicable, locate the transmission dipstick under the hood, typically near the back of the engine.
Extract and Inspect:
- Pull the dipstick out, wipe it clean, and reinsert it fully. Remove it again to check the fluid level. The fluid should be between the "Full" and "Add" marks.

Step 2: Adding Transmission Fluid

If Low, Add Fluid:
- With a funnel, add Toyota Genuine ATF WS fluid slowly through the dipstick tube until the correct level is reached.
Recheck the Level:
- After adding, recheck the fluid level to ensure it’s within the proper range.

Step 3: Fluid Change (If Necessary)

Gather Supplies:
- Make sure you have enough Toyota Genuine ATF WS fluid, a drain pan, and any necessary tools for your specific vehicle configuration.
Lift the Vehicle:
- Use a jack and jack stands to safely lift the vehicle.
Locate the Transmission Pan:
- The transmission pan will be at the bottom of the transmission.
Drain the Old Fluid:
- Place the drain pan under the transmission pan. Remove the drain plug (if equipped) or unbolt the transmission pan to allow the old fluid to drain completely.
Replace the Transmission Filter (if applicable):
- Remove the old filter, clean the mating surface, and install the new filter, ensuring it is seated properly.
Clean and Reinstall the Pan:
- Clean the pan and replace the gasket if necessary. Reinstall the pan and tighten the bolts to the manufacturer’s torque specifications.
Refill with New Fluid:
- Using a funnel, refill the transmission through the dipstick tube with the recommended amount of Toyota Genuine ATF WS fluid.
Check for Leaks:
- Start the engine and let it run for a few minutes, checking for any leaks around the transmission pan and drain plug.
Final Fluid Level Check:
- After the vehicle is back on level ground and warmed up, recheck the transmission fluid level and add more fluid if necessary.

Conclusion

Using the correct transmission fluid type is crucial for the performance and longevity of your 2020 Toyota Highlander. Always ensure that you adhere to manufacturer specifications and check fluid levels regularly as part of routine maintenance to prevent transmission issues.
