Abstract
The present invention is a method for invoking a shutdown on default and allowing recovery from a partial default. The method includes the steps of defining temporary default gears to be allowed for operation of the transmission, monitoring predetermined variables of the transmission by the controller and determining whether a fault has been detected based on the monitored predetermined variables. The method also includes disconnecting electrical power from the transmission by the controller if a fault has been detected, and determining whether faultless operation of the transmission has occurred for a predetermined time period by the controller if a fault has not been detected. The method further includes allowing shifting between additional gears if faultless operation of the transmission has occurred for the predetermined time period.
