OPERATING THE TRANSMISSION 5. Release the clutch pedal, then gradually accelerate to permit smooth starting, 6. Do not allow your vehicle to roll (even a little) in the opposite direction during clutch engagement. If you need to start up on an incline, apply your service brakes before you release the parking brake. Then release your service brakes as you engage the clutch and apply throttle. For further instructions on operating your transmission, see the transmission manufacturer's manual that is included with your vehicle. If you have a misaligned gear condition in your vehicle's transmission and cannot start, gradually release the clutch, allowing the drive gear teeth to line up properly. Then the drive gear can roll enough to allow the teeth to line up properly and complete the shift. The best engine performance and maximum economy is obtained if gears are properly selected. This efficiency is achieved by always selecting gears within optimum engine rpm, which is where maximum torque and power are obtained. For further information, see “More Driving Tips and Techniques” on page 130. STARTING AND OPERATING THE VEHICLE Shifting Gears in a New Vehicle Shift carefully in a new vehicle. The transmission may be a little stiff at first. Avoid gear clashing by closely following these procedures. When you are operating a new vehicle or one that has been exposed to cold weather, you want the transmission lubricant (fluid) to circulate and coat the contacting surfaces of the gears. Metal contacting metal in moving parts may seriously damage your transmission—do not drive in one gear for long periods of time until the transmission lubricant has a chance to coat all contacting surfaces. Carefully observe the free travel in the clutch for the first few hundred miles. As the clutch lining wears and high spots get worn smooth, you will get less free travel. Clutch Brake and Travel (9–, 10–, and 11–Speed Transmissions only) These transmissions utilize a clutch brake, rather than synchronizers. The clutch brake works by stopping all of the gears in the transmission, allowing you to easily shift into first gear or reverse without grinding gears.

STARTING AND OPERATING THE VEHICLE stroke of the clutch pedal is about 10 inches. The first part is the release stroke: the part that fully releases the clutch. The last inch engages the clutch brake. During hard-shifting with vehicle not moving • To apply the clutch brake (while the vehicle is stopped) fully depress the clutch pedal to the floorboard to stop the gears. With the throttle at idle, select first gear then release the clutch pedal to let the vehicle start forward, until the clutch is fully engaged. See the transmission manufacturer's manual that is included with your vehicle for further details. During Normal Driving If you want to shift directly into any gear other than first or reverse, depress the clutch pedal only far enough to release the clutch. Pushing the clutch to the floor applies the clutch brake and could cause gear hang-up. OPERATING THE TRANSMISSION CAUTION: Be careful not to apply the clutch brake while the vehicle is moving. The purpose of the clutch brake is to stop the transmission so that you can shift into a starting gear without grinding gears. Applying the clutch brake when the vehicle is moving causes a braking effect on the drivetrain and shortens the service life of the clutch brake. Double Clutching Whether you are upshifting or down shifting, it is best to double clutch. Double clutching is easier on the transmission and on the engine, helping your vehicle match engine speed with driveline speed and achieving clash-free shifts. To double clutch: 1. Push the clutch pedal down to disengage the clutch. 2. Move the gear shift lever to Neutral. 3. Release the pedal to engage the clutch. This lets you control the rpm of the mainshaft gears, allowing you to match the rpm of the mainshaft gears to those of the output shaft. Medium Duty (R05/09) Y53-6027 – 101 –
