- If fluid level is below the "Full" mark, proceed to the next step.
Step 2: Using a funnel, add the recommended transmission fluid (Toyota Genuine ATF WS) slowly through the dipstick tube.
- Add fluid in small increments, checking the level frequently to avoid overfilling.
Step 3: Reinsert the dipstick, ensuring it is fully seated after you finish adding fluid.

Shift through the gears once more and check for any leaks around the transmission area.
Ensure the dipstick is properly seated.
