Total agreement with Gnarls here, the valving on the rear is critical in avoiding an out-of-control downhill backwards front wheel slide can get scary. I learned the hard way when climbing a steep incline and ran out of steam in my auto 4Runner shifted into reverse was all that was needed to start sliding on the front and very little rear braking. The auto trans is has an electronic torque converter which if you know how to wire it you can shut off the stall which helps a lot. As to a stick, nothing beats gear reduction, Dual Marlin Ultimate's with 4:88's and 33's keep me putting along. Anyone that asks me about the setup my first reply is that my truck will not stop until it flops, with or with my guidance.
