Just for fun yesterday I perused Ram's website for the V6 quad cab truck in regards to towing. I was kinda surprised: if you order with 3.21 rear gearing (4x4, quad not crew, 6'4" bed) it is about 4,400 lb rated. But with the slightly deeper gearing of 3.55 it jumps to 7,400 lb. Seems a rather large jump for something that has relatively close spaced gear ratios in the 8AT. I mean, takeoff ratio is better (11%), but that's just off the line, and after that it shouldn't matter. Transmission picks the gear required for the rpm to make enough hp to accomplish what is being asked of it.
Watched a TFL vid the other night where they ran the Ecodiesel up the Ike. They seemed a bit taken back that it wouldn't do more than 55mph. 420ft-lb torque is nice, but in the end, once moving, 240 hp is still only 240 hp. At least it was still (mostly) 240hp & not suffering from altitude power loss like a NA engine would.
