or Position in 3rd gear

As the speed of the vehicle reaches the prescribed value, the PCM turns the shift solenoid valve B OFF. Shift solenoid valve A remains ON and modulator (SH B) pressure (6B) is applied to the right side of the 1-2 shift valve and to the left side of the 2-3 shift valve. The 2-3 shift valve is moved to the right side to switch the port leading CPC pressure (5) to the 3-4 shift valve, then CPC pressure (5) becomes the 3rd clutch pressure (30) at the 3-4 shift valve. The 3rd clutch pressure (30) is applied to the 3rd clutch and the 3rd clutch is engaged.

Line pressure (4) also flows to the 1st clutch and the 1st clutch is engaged. However, no power is transmitted because of the one-way clutch.

NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.
