PARKING

WARNING: For vehicles containing 1000 and 2000 Product Families transmissions without either P (Park) or PB (Auto­Apply Parking

Brake) selector positions, each time you park the vehicle or leave the operator’s station with the engine running, do the following:

1. Bring the vehicle to a complete stop using the service brake.

2. Make sure the engine is at low idle rpm.

3. Put the transmission in N (Neutral).

4. Apply the emergency brake and/or parking brake and make sure they are properly engaged.

5. If the operator’s station will be unoccupied with the engine running, chock the wheels and take any other steps necessary to keep the vehicle from moving.

If the procedure is not followed, the vehicle may move suddenly and cause injury and/or property damage.

REVERSE

WARNING: R (Reverse) may not be obtained due to an active inhibitor.

Check for the illumination of the RANGE INHIBIT(ED) light or CHECK

TRANS (MIL) light. See the

3.12 SHIFT INHIBITS

section of this manual.

P (PARK) OR PB (AUTO­APPLY PARKING BRAKE) POSITIONS

R

WARNING: To help avoid injury and/or property damage caused by unexpected vehicle movement, do not make shifts from R (Reverse) to N (Neutral) without applying the service brakes, parking brake, or emergency brake. Selecting N (Neutral) does not apply vehicle brakes unless an auxiliary system to apply a parking brake is installed.

CAUTION: Do not idle in R (Reverse) for more than five minutes.

Extended idling in R (Reverse) can cause transmission overheating and damage. Always select P (Park) whenever time at idle exceeds five minutes.

R (Reverse) is used to back the vehicle. Completely stop the vehicle and let the engine return to idle before shifting from a forward range to R (Reverse) or from R (Reverse) to a forward range. The reverse warning signal is activated when the shift selector is in this position.

NEUTRAL

N

WARNING: To help avoid injury and/or property damage caused by unexpected vehicle movement, do not make shifts to or from N

(Neutral) without manually or automatically applying an appropriate vehicle brake.

WARNING: DO NOT allow the vehicle to “coast” in N (Neutral). There is no engine braking in N (Neutral). You could lose control of the vehicle, causing property damage or personal injury. Coasting in neutral can cause severe transmission damage.

Use N (Neutral) for the following:

• To turn on or turn off the engine

• To check vehicle accessories

• To operate the engine at idle for longer than five minutes

• For stationary operation of the power takeoff (if your vehicle is equipped with a PTO

DRIVE

WARNING: D (Drive) and other forward ranges may not be obtained due to an active inhibitor. The range selected may not be obtained, resulting in unexpected vehicle movement. To help avoid injury and/or property damage, always apply the service brake when selecting D

(Drive) or other forward ranges. Check for the RANGE INHIBIT(ED) light or the CHECK TRANS (MIL) light.

D*

WARNING: To help avoid injury and/or property damage caused by unexpected vehicle movement, do not make shifts from a forward range to N (Neutral) without applying the service brakes, parking brake, or emergency brake. Selecting N (Neutral) does not apply vehicle brakes unless an auxiliary system to apply a parking brake is installed.

CAUTION: Do not idle in D (Drive) or any forward range for more than five minutes. Extended idling in D (Drive) can cause transmission overheating and damage. Always select P (Park) whenever time at idle exceeds five minutes.

NOTE: Turn off the vehicle HIGH IDLE switch, if present, before shifting from N (Neutral) to D (Drive) or R (Reverse). D (Drive) or R (Reverse) will not be attained unless the shift is made with the engine at idle.

Use D (Drive) for normal driving. The transmission will initially attain first range when D (Drive) is selected. As vehicle speed increases, the transmission will upshift automatically through each available range up to 4 (Fourth Range) or 5 (Fifth Range). As the vehicle slows, the transmission will downshift automatically.

The shift selector position representing this gear range may be labeled

“5” or “6” (for the highest gear in the range), “OD” (for Overdrive), “D”

(for the normal Drive position), “1–5” or “1–6”(for the complete gear range).

MANUAL SELECT

WARNING: The transmission incorporates a hold feature to prohibit upshifting above the range selected during normal driving. For downhill operation, select a lower transmission range. If the engine governed speed is exceeded in the held range, however, the transmission will upshift to the next higher range to prevent engine damage. To help avoid injury and/or property damage due to loss of vehicle control, use the vehicle brakes to prevent exceeding engine governed speed in the held range.

WARNING: To help avoid loss of control, use a combination of downshifting, braking, and other retarding devices. Downshifting to a lower transmission range increases engine braking and can help you maintain control. The transmission has a feature to prevent automatic upshifting above the lower range selected. However, during downhill operation, if engine governed speed is exceeded in the lower range, the transmission will upshift to the next higher range to prevent engine damage. This will reduce engine braking and could cause a loss of control. Apply the vehicle brakes or other retarding device to prevent exceeding engine governed speed in the lower range selected.
