D Position: Shifting between 1st gear and 2nd gear

WARNING: This page is about a different car, the 2013 Honda Fit, 2012 Honda Fit, 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.

As the speed of the vehicle reaches the programmed value, the PCM turns shift solenoid valve A ON, shift solenoid valve B remains ON, and shift solenoid valve C remains OFF. Shift solenoid valve A pressure (SA) is applied to the right end of shift valve A and to the left side of cut valve A. Cut valve A is moved to the right side to release 1st clutch pressure in line pressure mode, and shift valve A is moved to the left side to switch the line pressure port (5A) to the A/T clutch pressure control solenoid valve C pressure port (5C) leading to the 1st clutch. Also, shift valve A uncovers the 2nd clutch pressure port (20) leading A/T clutch pressure control solenoid valve B pressure (56) to the 2nd clutch. The 1st clutch and 2nd clutch are engaged by the A/T clutch pressure control solenoid valve pressure.

NOTE:

When used, "left" or "right" indicates direction on the hydraulic circuit.
The illustration shows the seven-position transmission; the manual-valve-position differs in the five-position transmission.
