The PCM turns shift solenoid valve B O N , and shift solenoid valve B covers the port of shift solenoid valve B pressure
(SB) to the shift valve B. Shift solenoid valve A keeps OFF, and shift solenoid valve C keeps O N . The shift valve B is
m o v e d to the left side to switch the port of line pressure (5H), CPC B pressure (5D) leading to the 5th clutch, and 4th
clutch pressure (40) releasing 4th clutch pressure. CPC B pressure (5H) changes to line pressure (5H) and 5th clutch
pressure (51) (50) is changed to line pressure mode, and the 5th clutch is engaged w i t h the line pressure mode. The 1st
clutch is also engaged, but no power is transmitted because of the one-way clutch.
NOTE: W h e n used, " l e f t " or " r i g h t " indicates direction on the hydraulic circuit.
