In 1st gear

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Honda Crosstour, 2014 Honda Crosstour, 2013 Honda Crosstour, 2012 Honda Crosstour, and 2011 Honda Accord Crosstour. However, it is still accessible from the selected car via links, so may be relevant.

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.
Power is transmitted to the final drive gear, which in turn drives the final driven gear and the front differential.
4WD: As the final driven gear turns the front differential, power is transmitted through the transfer drive gear to the transfer output shaft that drives the transfer hypoid drive gear/shaft and the transfer output shaft (hypoid gear).

NOTE: This illustration shows 4WD transmission, the 2WD does not have the transfer assembly.
