Solution

1. Preparation

Tools Required: Lint-free cloth, funnel (if adding fluid), gloves.
Ensure the vehicle is on a level surface and the engine is running for accurate fluid level reading.

2. Check Fluid Level

Open the hood and locate the transmission dipstick.
Pull the dipstick out and wipe it clean with a lint-free cloth.
Insert the dipstick back into the tube and ensure it is seated properly.
Pull it out again to observe the fluid level against the markings on the dipstick.
- If the fluid is below the 'full' mark, proceed to add fluid.

3. Add Transmission Fluid (if necessary)

Use a funnel to avoid spillage and open the transmission fill cap or dipstick tube.
Add the appropriate type of transmission fluid (check the owner's manual for specifications).
Add fluid in small increments (about ½ quart) and recheck the dipstick frequently until the proper level is reached.
Ensure not to overfill as this can damage the transmission.

4. Clean Up

Remove any spilled fluid and dispose of any used materials properly.
Close the hood securely after finishing.
