5. Replace with new fluid, ensuring the correct level is reached.

3. Inspect and Clean Transmission Cooler

Sub-steps:
1. Locate the transmission cooler (usually part of the radiator).
2. Inspect for any debris or obstructions.
3. Clean the cooler using compressed air or a soft brush to remove any blockages.
4. Check the lines for leaks or damage and replace if necessary.

4. Repair or Replace Damaged Components

Sub-steps:
