AUTOMATIC TRANSMISSION SYSTEM Pattern Select Switch Sport Mode Circuit

DESCRIPTION

The TCM memory contains the programs for the normal and sport shift patterns.

By following the programs corresponding to the signals from the SPORT S/S+ switch (integration control and panel assembly), the park/neutral position switch and other various sensors, the TCM switches the solenoid valves on and off, and controls the transmission gear change operation.
