Inspect the drained fluid for discoloration or burnt smell.
Replace with manufacturer-recommended transmission fluid, ensuring the correct type and quantity (check owner's manual for specifications).

3. Replace Transmission Filter (if applicable)

Tools Required: Socket set, gasket scraper.
Remove the transmission pan by unscrewing the bolts.
Remove the old filter and replace it with a new one, ensuring it is seated correctly.
Clean the transmission pan and install a new gasket before reattaching the pan.

4. Check and Repair Cooling System

Tools Required: Pressure tester, coolant.
Inspect the engine cooling system for leaks or malfunctions.
Ensure that the radiator and transmission cooler are clear of debris.
If necessary, replace any faulty components (thermostat, radiator, hoses).

5. Test Drive and Monitor

Reconnect the battery.
Start the vehicle and allow it to reach operating temperature.
Perform a test drive, monitoring for any signs of transmission issues.
