Cadillac 2009 owner manual Driver Shift Control DSC

The 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

will be 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 may appear to be

a delayed shift, however the transmission is operating normally.

The vehicle’s transmission uses adaptive shift controls that 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 controls process, shifting may feel different as the transmission determines the best settings.

When temperatures are very cold, the Hydra-Matic®6L80 automatic transmission’s gear shifting may

be delayed providing more stable shifts until the engine warms up. Shifts may be more noticeable with a cold transmission. This difference in shifting is normal.
