Pattern Select Switch Circuit

CIRCUIT DESCRIPTION
The Engine Control Module (ECM) memory contains the shift programs for the NORMAL and POWER patterns, 2 position, and L position and the lockup patterns. Following the programs corresponding to the signals from the pattern select switch, the park/neutral position switch and other various sensors the ECM switches the solenoid valves ON and OFF, thereby controlling the transmission gear change and the lockup clutch operation.
