In "L" Range
The line pressure (1), after passing through the manual valve, comes out as the line pressures (2) and (5). The line pressure (2) is applied to the forward clutch. In this state, as the 2nd brake solenoid valve is OFF because it is not electrically charged from the Transmission Control Module (TCM) (controller), the line pressure (1) is applied to the 1 - 2 shift valve. Then the line pressure is applied to the 1st-reverse brake. Consequently the 1st gear is attained. When the selector lever is shifted to L at a speed higher than 53 km/h (33 mile/h), the 2nd brake solenoid valve is electrically actuated and the solenoid valve opens to allow the line pressure (1) to be relieved. Then the 1 - 2 shift valve is pushed back by its return spring and the passage of the line pressure (5) is switched from the 1st-reverse brake to the 2nd brake piston. Therefore, the 2nd gear is attained until the vehicle speed lowers.
