In order to reduce drivetrain component wear and tear, a machine monitors for an impending downshift and automatically slows the machine to a speed that keeps engine rpm below a target engine rpm before the downshift is completed. A controller in the machine determines the current speed of the machine and then slows the machine to a new speed associated with the target rpm in the new gear. The controller may simply apply the brakes to slow the machine to the new speed independently of the process of changing gears or may actively delay the gear change until the new speed is achieved.
