ok, here's a real one I couldn't check during the test drive. I have the auto, and it has ZERO engine braking in 4LO.
Went up in the mountains last weekend in the snow. Dropped it in 4LO and let it crawl down the hill. Even though it was a moderate downhill, the engine braking couldn't keep up with the weight of the vehicle and it accelerated almost all the way to redline. Yes, it finally could hold up the vehicle, but it was revving a lot more than I'd want on anything more than a short downhill.
I've got a Cherokee (5sp) and Suburban (TH400) and both have significantly better compression braking. I'm actually a little concerned that, when I really need it (this was a breakin run), I'll be spending time on the brakes because the engine can't hold up the rig. I had more brake fade than I expected, but I'm assuming that wasn't fade, it was mud and snow on the rotors
I guess this is the tradeoff of a 5 cylinder? I don't see any problems with power, but less cylinders may equal less braking...
