Solution

1. Preparation

Gather necessary tools: funnel, clean rag, and possibly a transmission fluid pump if adding fluid.
Ensure the vehicle is parked on a flat surface and the engine is warm.

2. Check Fluid Level

Locate the Dipstick or Fill Plug: If your Tacoma has a dipstick, it will be near the back of the engine bay. If not, locate the fill plug on the transmission case.
Remove Dipstick or Plug: Pull out the dipstick or unscrew the fill plug using the socket set.
Inspect Fluid Condition: Wipe the dipstick clean and check the fluid on the rag. Look for a pink or red color; any darkening or burning smell indicates a need for fluid change.
Check Fluid Level: Reinsert the dipstick or plug, then remove it again to check if the fluid level is within the marked range. If it's below the minimum mark, fluid needs to be added.

3. Add Transmission Fluid (if necessary)

Select the Right Fluid: Refer to the owner's manual for the correct type of transmission fluid (typically Toyota ATF WS).
Add Fluid: Using a funnel, add the required amount of fluid through the dipstick tube or fill hole until it reaches the appropriate level.
Recheck Level: After adding, check the fluid level again to ensure it is correct.

4. Final Steps

Reinsert the dipstick or fill plug securely.
Clean any spilled fluid around the area.
