REVERSE GEAR
• Hydraulic pressure is applied to the servo valve to engage the reverse selector with the countershaft (reverse gear
while the shift lever is in the R position).
• 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 via 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.
