Rolling resistance from the road surface goes through the front wheels to the final drive gear, then to the sub-shaft 1st gear via the 4th gear and 1st-hold clutch which is applied during deceleration in position.
The one-way clutch becomes free at this time because the application of torque is reversed.
The counterforce conveyed to the countershaft 4th gear turns the sub-shaft 4th gear via the mainshaft 4th gear.
Hydraulic pressure is applied to the 1st-hold clutch and 1st clutch, then the 1st-hold clutch engages the sub-shaft 4th gear with the sub-shaft.
The sub-shaft 1st gear drives the mainshaft 1st gear and the mainshaft and counterforce is transmitted to the mainshaft. Engine braking can be obtained with 1st gear.
