English term or phrase:stall shifting
Preselection To Avoid Stall Shifting
When a machine must travel up a steep grade when loaded, a rapid loss in machine momentum can occur with a resulting full power shift into a lower range. Because of the loss of momentum, the shift may occur when the machine has almost stopped on the grade, at or near full converter stall which can shorten transmission life. To prevent these shifts, the operator should preselect the lowest range anticipated for the steep grade. After negotiating the steep grade, the gear selector control can be repositioned to a range appropriate for the balance of the haul cycle.
