The experienced crashbox drivers actually shift 'em without using the clutch, but that's a lesson for another day! The clutch is only used for starting and stopping- - - -all the shifts are made by easing up on the throttle and slipping the shifter in and out of position while there's no load on the gears. Try it with two transmissions in tandem- - - -5 speeds in one and 3 in the other! Two shifters to play with, and sometimes it's necessary to have both hands off the steering wheel! We learned not to make any shifts at all in a low-speed turn.
