1 Position
In 1 position, hydraulic pressure is applied to the 1st clutch and the 1st-hold clutch.
The power flow when accelerating is as follows:
• Hydraulic pressure is applied to the 1st clutch, then the 1st clutch engages the secondary shaft 1st gear with the
secondary shaft by the one-way clutch.
• Hydraulic pressure is also applied to the 1st-hold clutch, and the 1st-hold clutch engages the secondary shaft 1st
gear with the secondary shaft.
• The mainshaft 3rd gear drives the secondary shaft via the countershaft 3rd gear and the secondary shaft idler gear.
• The secondary shaft 1st gear drives the countershaft 1st gear and the countershaft.
• Power is transmitted to the final drive gear, which in turn drives the final driven gear.
