Solution

1. Preparation

Gather necessary tools and materials.
Tools Required:
- Funnel
- Clean lint-free cloth
- Gloves (to protect hands from fluid)
Ensure the vehicle is parked on a level surface and the engine is running and warmed up.

2. Check Fluid Level

Remove Dipstick
- Locate the transmission dipstick and pull it out.
Clean Dipstick
- Wipe the dipstick with a clean lint-free cloth to remove any old fluid.
Reinsert Dipstick
- Fully insert the dipstick back into the tube and remove it again to check the fluid level.
Check Fluid Level
- Observe the fluid level against the "Full" and "Low" markings on the dipstick. The fluid should be within this range.
Inspect Fluid Condition
- If the fluid is low, proceed to add transmission fluid; if it’s discolored or smells burnt, consider a fluid change.
Add Fluid if Necessary
- If the fluid is low, use a funnel to add the correct type of transmission fluid (Toyota Type T-IV or compatible fluid) as specified in the owner's manual.
- Add fluid in small increments, checking the level frequently to avoid overfilling.

3. Final Steps

Reinsert the dipstick and ensure it is secured properly.
Close the hood and ensure all tools are removed from the engine bay.
