2006 Jeep Grand Cherokee - Trans temp

same problem with transmission over temp light coming on I’ m going to flush the radiator and change the thermostat and see if that help

Good luck, but I suspect you need a new radiator to provide adequate cooling for your transmission.
Plus you must service your transmission fluid and filter.
