Removal

1. WARNING: On vehicles equipped with an auxiliary battery, both the negative and positive battery cables must be disconnected.

WARNING: On vehicles equipped with a 7.3L engine, both the primary and secondary batteries must be disconnected.

Note: All gasoline vehicles 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 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 operating conditions. There is no time frame set for this process. If a 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 temporary and will eventually return to normal operating condition.
