Diagnostic Steps

1
Locate the Transmission Dipstick: Open the hood and find the transmission dipstick, typically marked with a yellow handle.

Solution

1. Preparation

Tools Required: Clean rag, funnel, transmission fluid (if needed).
Ensure the vehicle is on a level surface and the engine is warmed up.

2. Check the Fluid Level

Remove the Dipstick: With the vehicle in 'Park' and the engine running, carefully pull the dipstick out.
Wipe the Dipstick: Use a clean rag to wipe off any fluid from the dipstick.
Reinsert the Dipstick: Fully reinsert the dipstick back into the tube.
Remove and Read the Level: Pull the dipstick out again and check the fluid level. It should be between the 'Full' and 'Add' marks.
Add Fluid if Necessary: If the fluid is low, use a funnel to add the appropriate Toyota ATF fluid until it reaches the 'Full' mark.

3. Fluid Condition Check

Inspect Fluid Color: Look at the fluid's color on the dipstick; it should be bright red.
Smell the Fluid: If the fluid has a burnt odor or is dark brown, consider a transmission fluid change.
Replace Dipstick: Once completed, ensure the dipstick is securely reinserted.
