Driving in 3rd gear
WARNING: This page is about a different variant/trim than selected.
The PCM turns shift solenoid valve A OFF and shift solenoid valve B ON in 3rd gear. As the speed of the vehicle reaches the programmed value, the PCM activates A/T clutch pressure control solenoid valve B, and applies CPC pressure (56) to the shift valve B pressure port (56). Shift valve B remains on the right side as with the 1st gear. The CPC pressure (56) from A/T clutch pressure control solenoid valve B becomes 3rd clutch pressure (30) at shift valve B, and flows to the 3rd clutch. Then the 3rd clutch is engaged by 3rd clutch pressure (30). 1st clutch is also engaged, but since the rotation speed of the countershaft exceeds that of 1st gear, no power is transmitted because the one-way clutch causes 1st gear to free-wheel.
NOTE:
When used, "left" or "right" indicates direction on the hydraulic circuit.
