1 Position (Deceleration)
The power flow in 1 when decelerating is as follows:
- Hydraulic pressure is applied to the 1st clutch and the 1st-hold clutch.
- Rolling resistance from the road surface goes through the front wheels to the final driven gear, then to the countershaft 1st gear.
- The one-way clutch cannot transmit the power from the countershaft 1st gear because the application of torque is reversed.
- The countershaft 1st gear drives the secondary shaft 1st gear, which in turn drives the secondary shaft via the 1st-hold clutch.
- The force transmitted to the secondary shaft idler gear turns the mainshaft 3rd gear via the countershaft idler gear. As a result, engine braking can be obtained with 1st gear.
