I enjoy the one in my 54. Although the truck has a cam that I think is not real hydra-matic friendly,(too high an idle for proper downshift), It is very pleasant to drive. Crisp firm shifts. The throttle pressure adjustment is ultra sensitive. It can go from running all four gears within about 10 feet, to not properly downshifting when rounding a corner with very little adjustment. I can't really comment on driving in hills as Oklahoma is pretty much bubble level flat.
