Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather necessary tools: a lint-free cloth for wiping the dipstick.

2. Check Fluid Level

Step 1: Start the engine and let it warm up to operating temperature (approximately 10 minutes).
Step 2: Shift the transmission through each gear, pausing briefly in each position before returning to "Park."
Step 3: Turn off the engine and remove the transmission dipstick.
Step 4: Wipe the dipstick clean to remove any fluid.
Step 5: Reinsert the dipstick fully back into the tube, then remove it again to check the fluid level.
Step 6: Compare the fluid level on the dipstick to the "Full" and "Add" markings; fluid should be within these ranges.

3. Add Fluid (If Necessary)

Step 1: If the fluid level is low, use a funnel to add the recommended ATF (Automatic Transmission Fluid) through the dipstick tube.
Step 2: Add fluid gradually and check the level frequently to avoid overfilling.
Step 3: Once the correct level is reached, reinsert the dipstick securely.
