Automatic Transmission
System Description (cont'd)
Hydraulic Flow (cont'd)
D Position: 1st gear shifting from the N position
Shift solenoid valves remain the same as in the N position when shifting to the D position from the N position. The
manual valve is moved to the D position, and switches the port of line pressure (4) leading to shift valve C and CPC
valve B. Line pressure (4) flows to the 1st clutch via the orifice. Line pressure (1) becomes CPC C pressure (4C) at CPC
valve C, then goes to the 1st accumulator back side. Line pressure (4) also becomes the CPC B pressure (4B) at the CPC
B valve. CPC B pressure goes to the 3rd clutch, via the shift valves C, B, and A, and the 3rd clutch is engaged. The 1st
clutch is engaged gently when shifting to the D position from the N position.
NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.
