206/306 - Delayed/Soft Forward Engagement

NOTE: Vehicles equipped with an OSS sensor will have new adaptive shift strategies. Whenever the vehicles battery has been disconnected for any type of service or repairs the strategy parameters that are stored in the Keep Alive Memory (KAM) will be lost. The strategy will start to learn once the battery is reconnected and the vehicle is driven. This is a normal condition and will go away once the PCM learns all the parameters from the driving conditions. There is no time frame set to this learning process. If this concern is present during down shifts or converter clutch apply, it is not the shift strategy and will require diagnosis.

The customer needs to be notified that they may experience slightly different upshifts either soft or firm and that this condition is normal and will eventually go away.
