D and D3 Positions: 1st gear shifting from the N position
Shift solenoid valves remain the same as in the N position w h e n shifting t o the D position f r o m the N position. The
manual valve is m o v e d t o the D position, and uncovers the port of line pressure (4) leading t o CPC valves A and C. The
PCM controls the A/T clutch pressure control solenoid valves A and C, A/T clutch pressure control solenoid valve A
pressure (56) f l o w s t o the CPC valve A, and A/T clutch pressure control solenoid valve C pressure (58) f l o w s to the CPC
valve C. The CPC valves A and C regulate line pressure (4), line pressure (4) becomes CPC C pressure (4C) at the CPC
valve C, and becomes CPC A pressure at the CPC valve A. CPC C pressure (4C) becomes 1st clutch pressure (10) at the
shift valve D, and 1st clutch pressure f l o w s t o the 1st clutch. CPC A pressure (4A) becomes 2nd clutch pressure (20) at
the shift valve B via the shift valve A. The 1st clutch and 2nd clutch engage gently w i t h the CPC pressure m o d e .
