The PCM turns shift solenoid valve C OFF, and shift solenoid valve C uncovers the port of shift solenoid valve C
pressure (SC) to the shift valve C. Shift solenoid valves A and B keep O N . The shift valve C is m o v e d to the right side to
switch the port of line pressure (4) and CPC A pressure (4A) leading to the 2nd clutch. CPC A pressure (5B) (5K)
changes to line pressure (5B) (5K) and 2nd clutch pressure (20) is changed to line pressure m o d e , and the 2nd clutch is
engaged w i t h the line pressure m o d e . The 1st clutch is also engaged, but no power is transmitted because of the one-
w a y clutch.
