Abstract

PURPOSE: To prevent the noise and the impact by the idling of the gear by shifting the manual valve to the stages except the first speed and the direct connection for a certain period of time after N-D, and clamping the brake at the stage at N position.
CONSTITUTION: When the manual valve is at N position, the clutch 12 and the brake are engaged. Then, by shifting the manual valve from N position to D position (N-D shift), the clutch is clamped at the second speed for a certain 1W2 seconds, which is set in advance, by the operation of the electric circuit to make the torque of the output shaft smaller than the state that the gear is at the first speed condition. Then, after a certain period of time, the electric circuit generates the signal of the first speed to release the brake and clamp the gear at the first speed position.
