DESCRIPTION
The ECM memory contains the programs for the normal and PWR shift patterns.
By following the programs corresponding to the signals from the pattern select switch assembly, park/neutral position switch and other various sensors, the ECM switches the shift solenoid valves on and off, and controls the transmission gear ratio.
