2006 Honda Pilot EX, 3.5 YF2, J35A9SECTION 1 Position (Acceleration)
In the 1 position under an acceleration, hydraulic pressure is applied to the 1st clutch and the 1st-hold clutch. The power flow when accelerating is as follows:
- Hydraulic pressure is applied to the 1st clutch, then the 1st clutch engages the secondary shaft 1st gear with the secondary shaft by the one-way clutch.
- The mainshaft 3rd gear drives the secondary shaft via the countershaft idler gear and the secondary shaft idler gear.
- The secondary shaft 1st gear drives the countershaft 1st gear and the countershaft.
- Hydraulic pressure is also applied to the 1st-hold clutch, and the 1st-hold clutch engages the secondary shaft 1st gear with the secondary shaft.
- Power is transmitted to the final drive gear, which in turn drives the final driven gear, and the transfer drive gear (4WD).
- 4WD: The transfer output shaft drives the transfer hypoid drive gear/shaft and the transfer output shaft (hypoid gear).
NOTE:
The illustration shows the 4WD transmission; the 2WD transmission does not have the transfer mechanism.
