The gearbox is placed in the engine facing toward the passenger compartment. The countershaft drives:•the front differential directly, by means of a propeller shaft
• the rear differential, by means of a transmission gear couple and of a propeller shaft by the crankcase side.
It has six synchronized ratios and reverse gear, without direct drive.Gearbox lubrication is ensured by a gear pump geared on the main shaft.
