The synchronizer rings are a poor design and cause a lot of grinding shifts.
Both engines are mated to standard six - speed manual transmissions that feature new carbon
synchronizer rings for smoother shift action and enhanced synchronizer durability.
It is based on the CLA's optional dual clutch unit but gets reinforced gear cogs and
synchronizer rings with carbon fiber friction rings for added durability.
The six - speed ASG transmission features heavy - duty
synchronizer rings and a newly developed gearshift actuator, providing the driver with a very direct shift feel.
The engine now matches revs on downshifts with the 8 - speed automatic transmission, and high - performance
synchronizer rings were added to the manual transmission for better shift feel.
The new transmission uses multi-cone
synchronizer rings on all gears for smoother shifting and a more positive shift feel as well as for improved durability.
There are three separate shift fork shafts, which hold three shift forks to activate
the synchronizer rings for the two gearsets on each of the three gear shafts.
Among its features is dry sump lubrication, a double - plate clutch to handle the added torque loading, carbon - ceramic friction linings within
the synchronizer rings and a blip function for downshifts.
As a means of increasing shift comfort, the manual gearbox uses innovative new carbon friction linings in
its synchronizer rings.
If there is a speed difference between the sleeve, synchroniser hub and gear, the sleeve is blocked by a «blocker ring» to prevent further travel of the sleeve,
the synchronizer ring creates friction to help match gear speeds.
the grinding sound you hear is that collar colliding with the end of the gear.the
synchronizer ring keeps things quiet and smooth in between shifts.
