Your vehicle has a shift stabilization feature that adjusts

the transmission shifting to the current driving conditions

in order to reduce rapid upshifts and downshifts. This shift

stabilization feature is designed to determine, before

making an upshift, if the engine is able to maintain vehicle

speed by analyzing things such as vehicle speed, throttle

position, and vehicle load. If the shift stabilization feature

determines that a current vehicle speed cannot be

maintained, the transmission does not upshift and instead

holds the current gear. In some cases, this could appear

to be a delayed shift, however the transmission is

operating normally.

Your vehicle’s transmission uses adaptive shift controls.

Adaptive shift controls continually compares key shift

parameters to pre-programmed ideal shifts stored in the

transmissions computer. The transmission constantly

makes adjustments to improve vehicle performance

according to how the vehicle is being used, such as with

a heavy load or when temperature changes. During this

adaptive shift control process, shifting might feel different

as the transmission determines the best settings.

When temperatures are very cold, the Allison

Transmission

and Hydra-Matic

6-Speed transmission’s

gear shifting could be delayed providing more stable

shifts until the engine warms up. Shifts could be more

noticeable with a cold transmission. This difference in

shifting is normal.

MANUAL MODE (M): This position, is available on

vehicles with the Allison Transmission

or Hydra-Matic

6-Speed transmission. It lets drivers select the range

of gears appropriate for current driving conditions.

If your vehicle has this feature, see Range Select

Mode (Allison Transmission

or Hydra-Matic

6-Speed transmission) later in this section.

THIRD (3): This position is also used for normal driving.

It reduces vehicle speed more than DRIVE (D) without

using the brakes. You might choose THIRD (3)

instead of DRIVE (D) when driving on hilly, winding

roads, when towing a trailer, so there is less shifting

between gears and when going down a steep hill.

SECOND (2): This position reduces vehicle speed even

more than THIRD (3) without using your brakes. You can

use SECOND (2) on hills. It can help control your speed

as you go down steep mountain roads, but then you

would also want to use the brakes off and on.

If you manually select SECOND (2) in an automatic

transmission, the transmission will start in second gear.

You can use this feature for reducing the speed of the

rear wheels when you are trying to start your vehicle

from a stop on slippery road surfaces.
