Honda 2004 Odyssey Service Manual page 914

D Position: Driving in 4th gear
The PCM turns shift solenoid valve C OFF, and controls A/T clutch pressure control solenoid valve B to release LS B
pressure (57) in CPC valve B. Shift solenoid valves A and B stays OFF. Releasing LS B pressure (57) in CPC valve B
releases CPC B pressure in the 3rd clutch pressure circuit. Shift solenoid valve C is turned OFF, and SH C pressure (SC)
is applied to the right side of shift valve C. Then shift valve C is moved to the left side to switch the port of line pressure
and CPC pressure. Line pressure (4) from the manual valve becomes 4th clutch pressure (40) at shift valve D via shift
valves C, A, and B, and flows to the 4th clutch. The 4th clutch pressure is changed to line pressure mode by switching
the position of shift valve C, and the 4th clutch is engaged securely. 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.
