Sherman A4A2 diesel 2-3 shift problem

Agree with the "non-choppy" use of brakes, with the provisio that you do not drag a tiller bar for long periods either. For example, compensating for road crown.

During the long 100 mile drives from Winnipeg to Shilo with the M113 FOV, you would almost wear out one arm continually making corrections. You would pull the tiller on and over correct for the wander, then let the tiller bar off. As the vehicle would wander back to the opposite away again, you repeated the process....again and again and again. But to simply pull the tiller bar to the point of allowing the drag compensate for the wander and then leaving it there would just result in overheating and burning the differential oil.

Perhaps the term "a series of smooth applications" might have been what John was trying to say. Simple turns can of course be accomplished by single applications of a tiller bar, as long as the oil temp is kept in it's operating range. When it exceeds that limit is when damage to the shoes and drums is going to occur.
