Main Control Valve Body: Removal

NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms can occur while the vehicle relearns its adaptive strategy. The customer needs to be notified that they may experience slightly different upshifts either soft or firm and this is a temporary condition and will eventually return to normal operating condition.
