Deceleration in 1 Position
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 idler gear.
- The one-way clutch disengages because the application of torque is reversed.
- The force conveyed 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.
NOTE:
The graphic shows the 4WD transmission; the 2WD transmission does not have the transfer mechanism.
