  1. Upshift one speed at a time. Increase engine speed, as required.


    NOTICE

    To prevent possible damage to the machine, reduce ground speed before downshifting.


    Note: Downshift speed protection is provided while you downshift, but the following steps are recommended:

  1. Downshift one speed at a time. When you downshift a loaded machine, increase the engine rpm in order to match the engine speed to the lower transmission gear speed.

  1. To change the machine's direction of travel, slow the machine by using the service brakes. Engage the transmission modulator control pedalin order to stop the machine. Then move the transmission direction and speed control to the position for the desired direction and for the desired speed. After you select the desired direction and the desired speed, release the service brakes and the transmission modulator control pedal.
