Hydraulic Oil Temperature Sensor: Hydraulic oil is needed for the gear lubrication system. Hydraulic oil temperature sensor measures the temperature of the oil. This car's sensor has a problem which may cause difficulty in shifting gears
Inspect the electrical connections in the hydraulic oil temperature sensor circuit for any signs of looseness, corrosion, or damage. Clean or repair the connections as necessary.
Check the wiring and harness for any visible damage or wear. Repair or replace the wiring if needed.
Test the hydraulic oil temperature sensor using a multimeter or diagnostic tool. Replace the sensor if it is found to be faulty.
If other possible causes have been ruled out, consider checking and updating the vehicle's control module software.
