R Position
- Hydraulic pressure is applied to the servo valve to engage the reverse selector with the countershaft reverse gear and the reverse selector hub while the shift lever is in R.
- Hydraulic pressure is also applied to the 4th clutch, then the 4th clutch engages the mainshaft reverse gear with the mainshaft.
- The mainshaft reverse gear drives the countershaft reverse gear via the reverse idler gear.
- The rotation direction of the countershaft reverse gear is changed by the reverse idler gear.
- The countershaft reverse gear drives the countershaft via the reverse selector, which drives the reverse selector hub.
- Power is transmitted to the final drive gear, which in turn drives the final driven gear, and the transfer drive gear (4WD).
- 4WD: The transfer drive gear drives the transfer drive gear (hypoid gear) and the transfer output shaft (hypoid gear).
NOTE:
The illustration shows the 4WD transmission; the 2WD transmission does not have the transfer mechanism.
