In 4th gear
- Hydraulic pressure is applied to the D inhibitor valve to engage the reverse selector with the third shaft 6th gear while the shift lever is in the forward range (D and S).
- Hydraulic pressure is applied to the 4th clutch, then the 4th clutch engages the third shaft 4th gear with the third shaft.
- Mainshaft rotation is transmitted to the third shaft 4th gear via the mainshaft 4th gear splined with the mainshaft
- Rotation of the third shaft 4th gear is transmitted to the third shaft 6th gear from the reverse selector hub via the reverse selector.
- The third shaft 6th gear drives the counter shaft 5th gear splined with the countershaft and the counter shaft via the mainshaft 8th gear.
- 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).
- Hydraulic pressure is also applied to the 1st clutch, but since the rotation speed of countershaft exceeds that of 1st gear, power output from 1st gear is cut off at the one-way clutch.
