Solution

1. Preparation

Gather necessary tools and materials, including a clean lint-free cloth and suitable transmission fluid if a refill is needed.

2. Checking Fluid Level

Ensure the vehicle is running and at normal operating temperature.
Remove the transmission dipstick from the tube.
Wipe the dipstick clean with a lint-free cloth.
Reinsert the dipstick fully into the tube, making sure it is seated properly.
Remove the dipstick again and observe the fluid level. The fluid should be within the "Full" and "Add" marks on the dipstick.

3. Adding Fluid (if necessary)

If the fluid level is low, locate the transmission fluid fill port (usually near the dipstick).
Using a funnel, add the recommended transmission fluid type (typically Toyota ATF WS) slowly to avoid overfilling.
Recheck the fluid level with the dipstick after adding fluid to ensure it's at the correct level.

4. Replacing Dipstick

Once the fluid level is confirmed, securely reinsert the dipstick into the tube.
Ensure it is seated properly to prevent any leaks.
