AUTOMATIC TRANSMISSION SYSTEM - Pattern Select Switch Power Mode Circuit


DESCRIPTION

The TCM memory contains the programs for the normal and power shift patterns.
By following the programs corresponding to the signals from the PWR switch (integration control and panel assembly), the park/neutral position switch and other various sensors, the TCM switches the shift solenoid valves on and off, and controls the transmission gear change operation.
