2. Transmission Fluid Replacement

Drain Old Fluid:
- Remove the drain plug using a socket set and allow old fluid to drain completely into a pan.
- Dispose of the used fluid according to local regulations.
Replace Filter (if applicable):
- Remove the transmission pan bolts with a ratchet and socket.
- Carefully remove the pan and replace the transmission filter if accessible.
- Clean the pan and magnet before reinstallation.
Add New Fluid:
- Reinstall the pan and tighten bolts to the manufacturer’s torque specifications.
- Using a funnel, add new CVT fluid through the fill tube. Refer to the owner’s manual for the correct type and quantity of fluid.

3. Inspect and Repair Cooling System

Check Coolant Flow:
- Inspect the radiator and transmission cooler for blockages.
- If necessary, flush the cooler with a suitable cleaning solution and water.
Replace Damaged Components:
- If any hoses or the radiator are leaking, replace them with OEM parts.
- Ensure all connections are tight and secure.
Test Cooling System:
- Refill the coolant system to the recommended level and check for leaks.
- Start the engine and monitor the temperature gauge to ensure proper cooling operation.

4. Address Driving Conditions

Advise the vehicle owner to avoid excessive towing or heavy loads that could contribute to overheating.
Discuss the importance of regular maintenance checks on the transmission.
