626 LX L4-2.0L DOHC (1999)
2-3 SHIFT OPERATION
The PCM controls a 2-3 shift by turning Shift solenoid 2 (SS2) OFF while Shift solenoid 1 (SS1) remains OFF. This results in spring force moving the
2-3 shift valve to the left side. In third gear, the P-14 band is released and the direct clutch is applied.
To release the 2/4 band, fluid under pressure in the D21 circuit moves through the 2-3 shift valve, servo release shuttle valve and 3-4 shift valve and
several circuits. Fluid in the SR circuit from the 3-4 shift valve releases the 2/4 band by opposing fluid under modulated line pressure in the SA circuit.
To apply the direct clutch, fluid under pressure from the D21 circuit moves through the 2-3 shift valve. The 3-2 timing and 2-3 shift valve block the
exhaust path for the DC circuit through the 34V circuit.
