1. NOTE: All gasoline vehicles will have new adaptive shift strategies. Whenever the vehicle's battery has been disconnected for any type of service
or repair the strategy parameters that are stored in the keep alive memory (KAM) will be lost. The strategy will start to relearn once the battery is
reconnected and the vehicle is driven. This is a temporary condition and will return to normal operating condition once the powertrain control
module (PCM) relearns all the parameters from the driving conditions. There is no set time frame for this process. If this concern is present during
downshifts or converter clutch apply, it is not the fault of the shift strategy and will require diagnosis as outlined in the workshop manual.
The customer needs to be notified that they may experience slightly different upshifts either soft or firm and that this is a temporary condition and
will eventually return to normal operating condition.
Disconnect the battery ground cable.
2. Raise the vehicle on a hoist.
3. Disconnect the connector.
4. Disconnect the shift cable at the manual control lever.
