1 Position (Deceleration)
The power flow in the 1 position when decelerating 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 drive gear, then to the secondary shaft idler gear.
- The one-way clutch disengages because the application of torque is reversed.
- The counterforce conveyed to the secondary shaft idler gear turns the mainshaft 3rd gear via the countershaft 3rd gear. As a result, engine braking can be obtained with 1st gear.
In the D position, the optimum gear is automatically selected from the 1st, 2nd, 3rd, 4th, and 5th gears (in the D position); 1st, 2nd, and 3rd gears (in the D position D3 driving mode) according to conditions such as the balance between the throttle opening (engine loading) and vehicle speed.
