2001 Chevrolet Silverado 1500 Pickup Owner's Manual - Page 114

6-Speed (VORTEC 8100 V8 and DURAMAX 6600 V8 Engines) t During the first 500 miles (805 km) of vehicle use, start the vehicle moving in FIRST (1) gear. This allows the clutch components to wear-in properly. FIRST (1): With the vehicle at a stop, release the brake, press the clutch pedal and shift into FIRST (1). Then, slowly let up on the clutch pedal as you press the accelerator pedal. Only downshift into FIRST (1) when the vehicle has come to a complete stop. If the shift lever will not go into FIRST (1), put the lever in NEUTRAL and let up on the clutch pedal to fully engage the clutch. Press the clutch pedal again. Then, shift into FIRST (1). SECOND (2): With the vehicle at a stop, release the brake, press the clutch pedal and shift into SECOND (2). Then, slowly let up on the clutch pedal as you press the accelerator pedal. With the vehicle moving, press the clutch pedal and upshift into SECOND (2) from FIRST (1) while applying light pressure to the right on the shifter. Then, slowly let up on the clutch pedal as you press the accelerator pedal. If you come to a complete stop and the shift lever will not go into SECOND (2), put the lever in NEUTRAL and let up on the clutch pedal to fully engage the clutch. Press the clutch pedal again. Then, shift into SECOND (2). Here's how to operate your transmission. This 6-speed pattern is unique to GM manual transmissions. The transmission always repositions the shift lever to NEUTRAL, which is located between FOURTH (4) and FIFTH (5) gear. To prevent unintentional gear selections, additional force is required to move the shift lever into REVERSE (R) or FIRST (1). Use FIRST (1) when trailer towing, driving with payload in the pickup box or launching on a grade. Otherwise, start in SECOND (2) gear. Only shift into FIRST (1) when the vehicle has stopped moving. 2-31
