Hydraulic pressure is applied to the servo valve to engage the reverse selector with the countershaft reverse gear while the shift lever is in R
Hydraulic pressure is applied to the 5th clutch, then the 5th clutch engages the mainshaft reverse gear with the mainshaft
The mainshaft reverse gear drives the countershaft reverse gear via the reverse idler gear
The countershaft reverse gear drives the countershaft via the reverse selector which drives the reverse selector hub
The rotation direction of the countershaft is changed by the reverse idler gear
With SH-AWD Power is transmitted to the final drive gear, which in turn drives the final driven gear and the transfer drive gear
Power is transmitted to the final drive gear, which in turn drives the final driven gear and front differential
With SH-AWD 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: The illustration shows the SH-AWD transfer assembly that is not available on all models
