May need to change out the thermostat, make sure the fans are working on the radiator, and check the transmission fluid level. The transmission may need a fluid and filter change.

Your welcome.

how can test the thermostat any sensor works ..? let me give the sensor test how can do if there ?


The thermostat would need to come out and put into a pan of water. Turn the stove on with a thermometer in the water, see at what temperature the thermostat opens. It should be at 195°
