Hey guys, on the subject of 4.7's and the AW4 I have a question:
Do I really need an external cooler? What generates heat? Generally, it's my understanding the slipping of the clutches create heat. I'll likely have full control with a RAD shifter, and I have the transgo kit in with full hotrod shifts.
In theory my AW4 should run cooler right? The gears will shift quickly rather than that nice smooth "heat-causing" granny shifts. If I'm manually shifting the thing while wheeling, do I need to run an external cooler?
It will help but the primary heat generator is the torque converter. If held at full stall they generate a huge amount of heat pretty fast. Driving on the highway where to usually locked I only see about 110-120 degrees. If I start climbing a pass and it unlocks for a while or when wheeling I see 160-180. And that's with a big cooler for an f350 and not running thru the radiator.
