Havent seen any forums about this. But the problem I'm having is when I try to hold a speed going uphill maybe 10-20 degree hill. It'll hold the speed fine no rpm bouncing. The truck doesn't shake. But I hear a chatter coming from engine bay it's not very loud I have to really listen to notice it. Kinda sounds like when you tighten the gas cap. As soon as I'm over the hill it imediately goes away. Thanks forum!
