4th Gear
- Hydraulic pressure is applied to the servo valve to engage the reverse selector with the countershaft 4th gear and reverse selector hub while the shift lever is in the forward range (D, 2, and 1 positions).
- Hydraulic pressure is also applied to the 4th clutch, then the 4th clutch engages the mainshaft 4th gear with the mainshaft.
- The mainshaft 4th gear drives the countershaft 4th gear and the countershaft.
- Power is transmitted to the final drive gear, which in turn drives the final driven gear, and the transfer drive gear (4WD model).
- 4WD model: The transfer drive gear drives the transfer drive gear (hypoid gear) and the transfer output shaft (hypoid gear).
NOTE:
The illustration shows 4WD model; 2WD model does not have the transfer mechanism.
