Owners manual say that even reverse has a synco.
From the service manual......
The manual transmission is a fully synchronized two-shaft transmission with six forward gears and one reverse gear. The 6th gear is used to save fuel and reduce engine speed. The manual transmission is equipped with a
conventional dry clutch with automatic wear adjuster which is operated by a central clutch operator. The transmission is maintenance-free and has a permanent oil fill. A precise and light shift with short shifting travels is achieved by the following measures:
²
Transmission of the shift lever movement to the transmission by the shift rod and control cable
²
Central shift shaft supported on needle bearings
²
Multiple-cone synchronization in 1st, 2nd, 3rd and 4th gear
² Fully-synchronized reverse gear
