Well after 1000 posts a guy does forget. I was thinking of a more recent thread. I don't know anything about the T-19 but with 5.11 first gear that still sounds like a granny tranny. While the truck type trannys are way tough and have their place you are still driving a 3 speed under most circumstances since you will seldom use first. If you do much city driving I think you would be happier with something else. And also for towing the gears are a long way apart on the T-18 and the NP 435. The T-10 is a true 4 speed.
