Shift strategy (4R100 automatic transmission)
To account for customer driving habits and conditions, your 4R100
automatic transmission electronically controls the shift quality by using an
adaptive learning strategy. The adaptive learning strategy is maintained by
power from the battery. When the battery is disconnected or a new battery
is installed, the transmission must relearn its adaptive strategy. Optimal
shifting will resume within a few hundred kilometers (miles) of operation.
If the shift quality does not improve within a few hundred
kilometers (miles) of operation, or if the downshifts and other
throttle conditions do not function normally, see your dealer or a
qualified service technician as soon as possible.
Understanding the shift positions of the 5–speed automatic
transmission (if equipped-Diesel engines only)
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.
P (Park)
This position locks the transmission and prevents the rear wheels from
turning.
To put your vehicle in gear:
• Start the engine
• Depress the brake pedal
• Move the gearshift lever into the desired gear
