1 - front of the crankcase, 2 - rear of the crankcase, 3 - clutch release bearing guide, 4 - cover, 5 - cover gasket
The gearbox has three shafts, a classic design with four synchronized forward gears and a non-synchronized reverse gear. The shift lever is on the floor.
Three versions of the manual four-speed gearbox can be used in cars:
- type A gearbox, in which the clutch housing is integral with the gearbox housing;
- type B gearbox, in which the clutch housing is integral or bolted to the gearbox housing;
- type C gearbox in which the clutch housing is bolted to the gearbox housing.
