My car has an automatic transmission.

If you have replaced the thermostat and radiator and the engine continues to run hot and cold and temperature is not controlled correctly. You should replace the cooling fan control switch and make sure all the air is removed from cooling system. Then retest to see if the cooling fan low and high speed is working correctly.
