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 1st-hold clutch which is applied during deceleration.
2. The 1st gear one-way clutch disengages at this time because the application of torque is reversed.
3. The counterforce conveyed to the countershaft 1st gear turns the mainshaft 1st gear. At this time, since hydraulic pres-
sure is also applied to the 1st clutch, counterforce is also transmitted to the mainshaft. As a result, engine braking can
be obtained with 1st gear.
