2. 2nd Gear
As the speed of the vehicle reaches the prescribed value, shift solenoid valve A is turned ON by means of the PCM.
Shift solenoid valve B remains ON. The modulator pressure (6A) in the left end of the 1-2 shift valve is released by turn-
ing shift solenoid valve A ON. The 1-2 shift valve is moved to the left side and uncovers the port to allow the line pres-
sure (5) to the 2nd clutch. The line pressure (5) becomes the 2nd clutch pressure (20) at the orifice. The 2nd clutch pres-
sure (20) is applied to the 2nd clutch, and the 2nd clutch is engaged.
Hydraulic pressure also flows to the 1st clutch. However, no power is transmitted because of the one-way clutch.
NOTE:
• When used, "left" or "right" indicates direction on the hydraulic circuit.
• The hydraulic circuit is for '96 - '98 models. On '99 - 01 models, the 2nd accumulator is different.
