Hydraulic pressure is also applied to the 5th clutch (4), then the 5th clutch (4) engages the mainshaft reverse gear (6) with the mainshaft (7).
The mainshaft reverse gear (6) drives the output shaft reverse gear (8) via the reverse idler gear (1).
The rotation direction of the output shaft reverse gear (8) is changed via the reverse idler gear (1).
The output shaft reverse gear (8) drives the output shaft (10) via the reverse selector, which drives the reverse selector hub (9).
IF AWD, power is transmitted to the final drive gear (33), which in turn drives the final driven gear (22) and the transfer drive gear (21). Then the transfer output shaft (23) drives the transfer case hypoid drive gear/shaft and the transfer output shaft/hypoid gear.
If FWD, power is transmitted to the final drive gear (33) which in turn drives the final driven gear (22), which turns the front differential assembly (28).
