Power Flow (cont'd)

Position

In position, hydraulic pressure is applied to the 1st clutch and the 1st-hold clutch.

The power flow when accelerating is as follows:

1. The hydraulic pressure is applied to the 1st clutch on the mainshaft, and power is transmitted via the 1st clutch to the

mainshaft 1st gear.

2. The hydraulic pressure is also applied to the 1st-hold clutch on the countershaft. Power transmitted to the mainshaft

1st gear is conveyed via the countershaft 1st gear to the 1st gear one-way clutch, the 2nd gear one-way clutch, and the
1st-hold clutch. The one-way clutches are used to drive the countershaft, and the 1st-hold clutch drives the counter-

shaft.

3. Power is transmitted to the secondary drive gear, which drives the secondary driven gear.
