“2” Second
Use this position for driving on more severe conditions
and lower speeds than “3” third. To prevent excessive
engine speed do not exceed 25 mph (40 km/h) in this
range.

“1” First
Use this position for driving up very steep hills and for
engine braking at low speeds 12 mph (19 km/h) or less
when going downhill. To prevent excessive engine speed,
do not exceed 12 mph (19 km/h) in this range.

NOTE:

Use caution when operating a heavily loaded

vehicle in “2” Second or “1” First gear selections in high
ambients as torque converter slip can impose significant
additional heat load on the cooling system.

Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled 5th and 6th (if equipped) speed

(Overdrive). The transmission will automatically shift
from Drive to Overdrive if the following conditions are
present:

• the transmission selector is in Drive;
• the engine coolant has reached normal operating tem-

perature;

• vehicle speed is above approximately 38 mph (61

km/h) for 5th gear and 55 mph (89 km/h) for 6th gear;

• the “TOW HAUL O/D OFF” switch has not been

activated;

• transmission has reached normal operating tempera-

ture.

NOTE:

If the vehicle is started in extremely cold tem-

peratures, the transmission shift schedule initially re-
stricts transmission operation in forward gear ranges to
3rd gear until the transmission fluid temperature rises to
