Manual Transmission Operation

5-Speed (VORTEC 6000 V8 and 6.5L
V8 Diesel Engines)

Here’s how to operate
your transmission.

FIRST (1) is intended only for heavy loads or trailer
towing and is not recommended for normal driving.

During the first 500 miles (805 km) of vehicle use, start
your vehicle moving in FIRST (1). This allows clutch
components to break

-

in properly.

FIRST (1): Press the clutch pedal and shift into
FIRST (1). Then, slowly let up on the clutch pedal as
you press the accelerator pedal. Shift into FIRST (1)
only when the vehicle is below 5 mph (8 km/h). If you
try to shift down into FIRST (1) at excessive vehicle
speeds, the shift lever will not move into the FIRST (1)
position until vehicle speed is reduced.

SECOND (2): Press the clutch pedal and shift into
SECOND (2). Then, slowly let up on the clutch pedal as
you press the accelerator pedal.

You can shift into SECOND (2) when you’re going less
than 20 mph (32 km/h). If you’ve come to a complete
stop and it’s hard to shift into SECOND (2), put the shift
lever into NEUTRAL (N) and let up on the clutch.
Press the clutch pedal back down. Then shift into
SECOND (2). If you try to downshift into SECOND (2)
at excessive vehicle speeds, the shift lever will not move
into the SECOND (2) position until the vehicle speed
is reduced.

THIRD (3): Press the clutch pedal and shift into
THIRD (3). Then, slowly let up on the clutch pedal as
you press the accelerator pedal.
