  • Method for controlling the internal electronic range selection for a 9 speed automatic transmission
    Patent number: 10514094
    Abstract: A method for controlling internal electronic range selection for an automatic transmission includes: confirming if a range change command has been ordered from a current transmission operating state; verifying expected performance from at least first and second mode valves and a park servo are present in the current transmission operating state prior to allowing a range change event; during the range change event: generating proactive commands including ordering a reduction in a hydraulic system pressure; and identifying if an unexpected event is detected; and following completion of the range change event confirming expected performance is obtained from at least the first and second mode valves and the park servo to achieve a driver intended state.
