In 1st gear
- Hydraulic pressure is applied to the 1st clutch, then the 1st clutch engages the secondary shaft 1st gear with the secondary shaft.
- Mainshaft rotation is transmitted to the mainshaft 4th gear splined with the mainshaft
- The mainshaft 4th gear drives the secondary shaft idler gear splined with the secondary shaft and the secondary shaft via the idler gear shaft idler gear.
- The secondary shaft and the secondary shaft 1st gear engaged by the 1st clutch, and the secondary shaft 1st gear drives the countershaft 1st gear.
- The countershaft 1st gear drives the park gear splined with the countershaft via the one-way clutch.
- Power is transmitted from the countershaft to the final drive gear, which in turn drives the final driven gear and the transfer drive gear.
- As the final driven gear turns the differential assembly, 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).
