auto trans and backing

[Matt400]

Well that is the idea, to engage the clutch fan... but how do you do that without turning on the A/C?

I just flip a switch on mine, I developed a kit that fools the ECM into thinking the engine needs more cooling so then the ECM powers up the fan clutch... . works real sweet. PM me if you want more info. It only works on 03 and newer trucks.
