The tranny on the one I drove worked good, you could feather the gas pedal to coast to a stop without breaking your neck like I saw the other guys do. I used it for work, At the Nascar races to respond to emergencies and carry people. We didn't have it loaded to much but it ran pretty fast. I didn't notice it bog down at all. It was only loaded with 500Lbs of people and 150 of gear though.
