1994 Ford F53 Transmission Temperature
I have a 1994 Itasca Suncruiser with a Ford F53 chassis. I installed a transmission temperature gauge and a cooler fan on the transmission cooler. I have read a lot about the safe temperature being 180 degrees, but when driving on mountains in external temperatures of 85 or more with a tow vehicle, my temperature bumps up to 210 degrees. It doesn't get higher. The trans temperature will drop when the external temperature drops or if it rains. If the external temperature is very hot, on level roads, the tran temperature is around 195.
Are these temperatures considered normal under these driving conditions?
