D Position: Shifting between 3rd gear and 4th 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 OFF, and shift solenoid valve C remains ON. Shift solenoid valve A pressure (SA) is applied to the right end of shift valve A and to the left end of cut valve A. Shift valve A is moved to the left side to switch the line pressure port (5L) to the A/T clutch pressure control solenoid valve C pressure port (5K) leading to the 3rd clutch. Also, shift valve A uncovers the 4th clutch pressure port (40) leading the A/T clutch pressure control solenoid valve B pressure (5H) to the 4th clutch. The 3rd clutch and 4th 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.
