2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Use a fluid pump to extract old transmission fluid from the fill tube.
3. Inspect the old fluid for debris or burnt smell.
4. Replace with manufacturer-recommended transmission fluid, ensuring to fill to the correct level as indicated on the dipstick.

3. Inspect and Clean Transmission Cooler

Sub-steps:
1. Locate the transmission cooler and associated lines.
2. Disconnect the lines using a wrench; be prepared for fluid spillage.
3. Flush the cooler with a cleaner designed for transmission coolers to remove any blockages.
4. Reattach the lines, ensuring all connections are tight and leak-free.

4. Verify Radiator Functionality

Sub-steps:
1. Inspect the radiator for dirt, debris, or any blockages obstructing airflow.
