Position
The power flow when decelerating is as follows:
1. Rolling resistance from the road surface goes through the front wheels to the secondary drive gear, then to the counter-
shaft 1st gear via the Ist-hold clutch which is applied during deceleration.
2. Power transmitted to the countershaft 1st gear is conveyed via the 1st gear one-way clutch on the inside of the counter-
shaft 1st gear to the countershaft 2nd gear. The 1st gear one-way clutch is used to drive the countershaft 2nd gear.
3. The 2nd gear one-way clutch disengages at this time because the application of torque is reversed.
4. The counterforce conveyed to the countershaft 1st gear turns the mainshaft 2nd gear. At this time, since hydraulic pres-
sure is applied to the 2nd clutch, counterforce is transmitted to the mainshaft. As a result, engine braking can be
obtained with 2nd gear.
