I'd say it's a shorted module. I've seen it with my testing if I cross wires by accident it'll do allll sorts of weird junk. Wipers, lights go wonky says truck is in gear key won't do anything. Could try to get a junk yard unit and try it.
I usto tow alot with my 2015. Over max towing capacity by about 2000lb and I never seen my trans get too hot with the factory cooler. Personally I don't see it being much use if the factory cooler can keep temps down through the Yukon Mountain. Go with the throttle body 100%
Oh no I seriously considered it but didn't want to build a divorced t case out of the factory 44-44 unit or build new driveshafts.
I even considered an ls swap because I found a supercharged crate ls for 2k cheaper than the 6.4 :eek:
Yupp I have the 8hp70 trans and a challanger 6.4 in my truck. Been strong for roughly 3 years now. I love it. Just need a tune and basic hand tools nothing crazy.
