RM3660EC _52 Drivetrain _080728 K313 CVT _0392261 CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM J

K313 CVT  CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM  Pattern Select Switch Sport Mode Circuit  


DESCRIPTION

The ECM memory contains programs for normal and sport shift patterns.

By following the programs corresponding to signals from the SPORT switch (combination switch assembly), park/neutral position switch assembly and various other sensors, the ECM switches the shift control solenoid valves on and off, and controls the transaxle gear ratio.
