626 LX L4-2.0L DOHC (1999)
3-2 SHIFT OPERATION
The PCM controls a 3-2 shift by turning Shift solenoid 2 (SS2) ON while Shift solenoid 1 (SS1) remains OFF. This results in fluid pressure in the S2
circuit moving the 2-3 shift valve to the right side. In second gear, the 2/4 band is applied and the direct clutch is released.
To release the direct clutch, the 2-3 shift valve blocks the D21 circuit and opens an exhaust path for the 34V circuit. The PCM controls the position of
the 3-2 timing valve as it varies the rate of fluid exhaust from the DC circuit into the 34V circuit.
The SR circuit connects through the DCX circuit and servo release shuttle valve to the DC circuit. Pressure in the SR circuit cushions the servo apply.
To apply the 2/4 band, fluid under pressure in the D21 circuit moves through the 1-2 shift valve, 2-3 shift valve and 3-4 shift valve and several
circuits. Fluid in the SA circuit from the 3-4 shift valve applies the 2/4 band.
