This might seem like a stupid question and maybe it is not allowed in rockcrawling comps, but why don't we see hydrostatic transmissions? seems like they would give much better low end torque and more controll than any automatic. the one in our tractor is sweet for going real slow. I know they are heavy, but so is a tranny and a tcase. so it seems like with the cash that everyone is spending for their crawlers that only see the trails you could even mount a motor on each axle and eliminate drivetrain worries. Maybe I just have too much time on my hands???
