Solution

1. Preparation

Gather tools: transmission dipstick (if applicable), clean rag or paper towel, funnel (if adding fluid).
Ensure the vehicle is parked on a level surface and the engine is running.

2. Check Fluid Level

Remove the transmission dipstick or fill plug.
Wipe clean with a rag to ensure accurate reading.
Reinsert the dipstick or plug fully, then remove it again to check the fluid level against the marked indicators (full, low).
If fluid is low, proceed to the next step to add fluid.

3. Add Transmission Fluid (if necessary)

Select the correct transmission fluid type specified in the owner's manual (typically either ATF or a specific type for Toyota).
Using a funnel, carefully add fluid through the dipstick tube or fill plug until it reaches the proper level.
Avoid overfilling, as this can cause transmission issues.

4. Final Checks

Reinsert the dipstick or fill plug securely.
Start the engine and allow it to idle for a few minutes.
Shift through the gears again to circulate the fluid and recheck the level.
