As the speed of the vehicle reaches the prescribed value, the PCM turns shift solenoid valve A OFF. The PCM also
controls the A/T clutch pressure control solenoid valve B to apply LS B pressure (57) to CPC valve B. Shift solenoid
valve B keeps ON, and C keeps OFF. Shift solenoid valve A is turned OFF, and SH A pressure (SA) is applied to the
right side of shift valves A and E. Then shift valves A and E are moved to the left side to switch the port of line pressure
and CPC pressure. Line pressure (4) becomes CPC A pressure (4A) at CPC valve A, and becomes CPC B pressure (4B)
at CPC valve B. CPC B pressure (4B) becomes 3rd clutch pressure (30) at shift valve A via shift valves C and B, and
flows to the 3rd clutch. The 2nd clutch pressure is changed to CPC pressure mode by switching the position of shift
valve A. The 1st clutch is also engaged. No power is transmitted because of the one-way clutch.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.
