D4 Position: 1st gear shifting from the N position
The PCM turns the shift solenoid valves A and C ON when shifting to the D4 position from N. Shift solenoid valve B
keeps ON. Shift solenoid valve C is turned ON, and SH C pressure (SC) in the right side of the shift valve C is released,
then the shift valve C is moved to the right side. Shift solenoid valve A is turned ON, and SH A pressure (SA) in the left
side of the shift valve A is released, then shift valve A is moved to the right side. The A/T clutch pressure control
solenoid valve A regulates LS A pressure (56) and applies it to CPC valve A. Line pressure (1) becomes line pressure
(4) at the manual valve, and flows to shift valve C and CPC valve A. Line pressure (4) becomes CPC A pressure (4A) and
passes through shift valve C, A, and B, then CPC A pressure (4A) becomes 1st clutch pressure (10) at shift valve B. 1st
clutch pressure (10) is applied to the 1st clutch, then the 1st clutch is engaged with pressure of the CPC pressure mode.
Line pressure (4) passes through shift valve A and B, then stops at shift valve B.
NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.
