R Position
- Hydraulic pressure is applied to the D inhibitor valve to engage the reverse selector with the third shaft reverse gear while the shift lever is in R.
- 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 from the reverse selector hub that rotates with the third shaft to the third shaft reverse gear, via the reverse selector.
- The third shaft reverse gear drives the mainshaft 3rd gear via the reverse idler gear.
- The mainshaft 3rd gear drives the countershaft 2nd gear splined with the countershaft.
- The rotation direction of the countershaft is changed by the reverse idler gear.
- Power is transmitted from the countershaft to the final drive gear, which in turn drives the final driven gear.
