Operating Instructions, 2000 and B200 Series Transmissions
2000 and B200 series transmissions are electronically controlled. The shift selector provides four forward ranges and one reverse range. A T-handle shift control is used by the driver to select the ranges. See Fig..
Fig. 1, T-Handle Shifter (standard)
P (Park)
Use park, if so equipped, when turning the engine on or off, to check vehicle accessories, or to operate the engine in idle for longer than 5 minutes. This position places the transmission in neutral and engages the park pawl of the transmission.
Note: This does not apply the parking brake.
The park pawl is standard on the 2200 series transmission. The park pawl effectively grounds the transmission output shaft, thereby preventing rotation of the driveline. Provided the vehicle is stationary, selecting P (park) on the shift selector, if so equipped, places the transmission in neutral and engages the park pawl.
PB (Auto-Apply Parking Brake, optional on 2000 and B200 Series)
The auto-apply parking brake places the transmission in neutral and applies the parking brake.
R (Reverse)
Reverse is used to back the vehicle. When the selector is in reverse, the reverse warning signal will sound. Always bring the vehicle to a complete stop before shifting from a forward range to reverse, or from reverse to a forward range.
Do not idle in reverse for more than 5 minutes. When time at idle exceeds 5 minutes, select N (neutral), or if so equipped, P (park) or PB (auto-apply parking brake).
Note: The shift into reverse may not succeed if a range inhibitor is active. Check for illumination of the RANGE INHIBIT indicator.
N (Neutral)
The neutral position places the transmission in neutral. When neutral is selected, the vehicle service brakes, parking brake, or emergency brake must be applied. Selecting neutral does not apply vehicle brakes unless an auxiliary system to apply the parking brake is installed.
This position is used when starting the engine and for stationary operation. It is also used to shut down the vehicle when P (park) or PB (auto-apply parking brake) are not available on the shifter. In this case, the parking brake must be applied.
Do not let the vehicle coast in neutral. If the vehicle is allowed to coast in neutral, the engine brake will not work and the driver could lose control of the vehicle.
D (Drive)
In the drive position, the transmission will initially go into first range when drive is selected. As vehicle speed increases, the transmission will upshift automatically through each available range up to fourth or fifth range. As the vehicle slows, the transmission will downshift automatically.
When going downhill, downshift to a lower transmission range to increase engine braking and to help maintain control. The transmission has a feature to prevent automatic upshifting above the lower range selected. However, during downhill operation, the transmission may upshift to the next higher range, if the engine is exceeding its governed speed in the lower range.
Note: The shift into drive may not succeed if a range inhibitor is active. Check for illumination of the RANGE INHIBIT indicator.
3 and 2 (Third and Second Ranges)
Use the third or second range for heavy city traffic and for braking on steeper downgrades.
L (Low Range)
Use low range when pulling through mud or deep snow, when maneuvering in tight spaces, or when driving up or down very steep grades. Low range provides the vehicle with its maximum driving torque and maximum engine braking effect.
Note: To have the transmission select these ranges automatically, leave the selector lever in D (drive).
