Driving
transmission. Once the vehicle is at operating temperature it may take
several shifts at the same operating condition for the transmission to
properly adapt. Over time the adaptive learning process will fully update
transmission operation. The more varied the driving habits, speed and
torque, the longer it may take to adapt but the more complete the
process will be.
When the battery is disconnected or a new battery installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will not affect function or durability of the transmission. Over time the
adaptive learning process will fully update transmission operation to its
optimum shift feel.
Driving with a 5–speed automatic transmission with the Select
Shift Transmission (SST) shifter (if equipped)
Your transmission is equipped with an adaptive learning strategy found in
the vehicle computer. This feature is designed to increase durability, and
provide consistent shift feel over the life of the vehicle. A new vehicle or
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation. Additionally, whenever the battery is
disconnected or a new battery installed, the strategy must be relearned.
Understanding gearshift positions
The Select Shift Transmission (SST) shifter allows the driver to select
between the transmission's automatic shift mode or the manually
selected shift mode.
