Location: Soquel, CA. | I installed an aftermarket transmission cooler that included a fan that I can turn on or off (I added a switch on my dash). I like having the fan, but I think it only makes about a 5 degree difference. However, sometimes that is an important 5 degrees.
I have a temp gauge for the transmission fluid. Cannot say how accurate it is, but it often tracks with the engine coolant temp if warm (drops way down when there is no strain at all). I try to keep it in the same range that is comfortable for the engine coolant. So, under 230; but I start taking action if it gets to 220. If it starts creeping up in that direction, I slow down and downshift. That usually gets me over any grade. Also, I am usually pulling a car too, so I have to watch my temps carefully if going up grades or driving at speed in very hot weather. |
