Scott, I came back from Duvall at 40-45k gcw in dump truck. Mind you it is a 175/330 non turbo 7.3 V8! Fortunately, 7 forward gears. In 1st which is 10.08-1, 2800 rpm at switch back motor starts slowing down to 2100 as I straighten back up, motor speeds up.....thought I was going to have to back down with 5 yrs of soil in truck, 12k equipment trailer behind me!
Needed clean shorts after that.
Never as of yet have I stalled that rig on a hill! My auto trans 454s, stalled them out all the time. One was a 4ad, into 4lo, no big. Rwd dually, burned up transmissions every 30k like clockwork, with 5k fluid fluid change.....talking COMPLETE fluid change including fluid into the TC!
