Driving in 4th Gear
WARNING: This page is about a different car, the 2013 Honda Odyssey, 2012 Honda Odyssey, and 2011 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
The PCM turns shift solenoid valve A OFF, and covers the shift solenoid valve A pressure port (SA) to shift valve A. Shift solenoid valves B and C remain OFF. Shift valve A is moved to the left side to switch the pressure port (5B), the CPC A pressure ports (5A) (5L) leading to the 4th clutch, and 3rd clutch pressure (30) releasing 3rd clutch pressure. CPC A pressure (5L) changes to line pressure (5L) and 4th clutch pressure (40) is changed to line pressure, and the 4th clutch is engaged by line pressure. The 1st clutch is also engaged, but no power is transmitted because of the one-way clutch.
NOTE:
When used, "left" or "right" indicates direction on the hydraulic circuit.
