Two-Speed Rear Axle - GMC C series 2002 Owner's Manual

Clutch Brake (Vehicles with
Non-Synchronized Transmission)
A clutch brake is used to stop transmission input shaft
rotation so that FIRST (1) or REVERSE (R) gear
selection can be initiated when the vehicle is at a
standstill and the engine is idling.
When using the clutch brake, disengage the clutch pedal
and shift the transmission into either FIRST (1) or
REVERSE (R) gear. If the tooth
between the clutching teeth, re
applying light pressure to the shift lever. This will
provide for a smooth shift into either FIRST (1)
or REVERSE (R) gear.
NOTICE:
After engaging FIRST (1) or REVERSE (R) gear,
do not use the clutch brake for upshifting and
downshifting. To do so will shorten the service life
of the clutch brake and gear selection shift efforts
may be increased.
