Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues during the repair.

2. Change Transmission Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Place a drain pan underneath the transmission pan.
3. Remove the transmission pan bolts using a socket wrench and carefully lower the pan.
4. Allow the old transmission fluid to drain completely.
5. Replace the transmission filter if applicable.
6. Clean the transmission pan and magnet thoroughly to remove any debris.
7. Reinstall the transmission pan with a new gasket, ensuring to torque the bolts to the manufacturer's specification.

3. Inspect and Repair Cooling System

Sub-steps:
1. Inspect the transmission cooler lines for any kinks or damage.
2. Check the transmission cooler for blockages or leaks.
3. If the cooler is blocked, flush it with a suitable cleaning solution.
4. Ensure the radiator fan operates correctly; replace if faulty.
5. Reconnect all lines and ensure that there are no leaks.

4. Test Drive and Monitor

Sub-steps:
1. Reconnect the battery.
2. Start the engine and allow it to reach operating temperature.
3. Engage the transmission through all gears while monitoring for any unusual behavior.
4. Check the transmission fluid level after the engine has warmed up and adjust if necessary.
