DESCRIPTION
The ECM memory contains the programs for the normal and sport shift patterns.
By following the programs corresponding to the signals from the No. 1 pattern select switch assembly, the park/neutral position switch and other various sensors, the ECM switches the shift control solenoid valves on and off, and controls the transaxle gear ratio.
