Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace CVT Fluid

Sub-steps:
1. Locate the CVT fluid dipstick and remove it to check fluid level.
2. If fluid is low or contaminated, drain the CVT fluid using a fluid pump.
3. Replace with OEM CVT fluid (refer to the owner's manual for specifications).
4. Recheck fluid level after replacement and run the engine briefly, then recheck.

3. Inspect Transmission Cooling System

Sub-steps:
1. Check the transmission cooler for any blockages or damage.
2. Clean or replace the cooler if necessary.
3. Inspect cooling lines for leaks or kinks and replace if damaged.
4. Ensure that the radiator is functioning properly and not obstructed.

4. Replace Transmission Temperature Sensor

Sub-steps:
1. Locate the transmission temperature sensor (refer to repair manual for exact location).
2. Disconnect the electrical connector and unscrew the sensor.
3. Install the new sensor and reconnect the electrical connector.
4. Clear any error codes from the OBD-II scanner.

5. Reconnect Battery and Test Drive

Sub-steps:
1. Reconnect the battery terminals.
2. Start the engine and allow it to reach operating temperature.
3. Test drive the vehicle under various conditions to monitor transmission performance.
