2014 Mercedes CLA Six-speed Manual Transmission



The six-speed manual transmission: Comfortable manual gearshifts


The new six-speed manual transmission was developed in parallel with 7G-DCT. It is extremely compact and shares a number of common parts.
The three-shaft transmission is also very compact (length 345 mm) and light (dry weight 46 kg) and incorporates a number of special features for particularly pleasant gearshifting. An integrated magnet on the gearshift shaft is detected by a Hall sensor. The idle position is identified in this way, making the start/stop function possible. The signal for reverse gear activates the reversing lights.


The large spread of 6.7 allows a reduction in engine speed while at the same time ensuring that sufficient tractive power is available when moving off with a fully laden Mercedes-Benz A-Class and trailer up to a gross weight of 3.4 tonnes. The clutch is operated hydraulically and the gears are actuated via cables.


The overhead camshaft with third and fourth gears and the reverse gear do not run in the oil bath. This reduces drag torque, thus facilitating gear shifting at low temperatures in particular. The three-cone synchronization of the first two gears serves the same purpose, while the following gears are provided with two-cone synchronization. The weight-optimized cast aluminum shift forks are installed on anti-friction bearings on the shift rods, in order to reduce the shift forces.

The cable shifters will make for lighter shifts but not as tight and reactive as linkages. Seems like most front wheel drive cars use cables.

I noticed that too with new cars. Linkages give the driver a more direct feel when it comes to front wheel drive vehicles but linkages are not as durable as we think they are. Most of the vehicles in the past that use linkages was due to get new ones or have issue later. And one thing im sure a lot can appreciate is the little effort and forced needed to shift with the cable types.

Perhaps if BMW sells enough 2-series cars with manual transmissions, then maybe Mercedes will reconsider and offer a manual transmission CLA in the USA. One can only hope!

I think BMW already has plans for this on the 2-series, they have always been the brand that stayed driver focus where ever appropriate, if they don't offer a manual in the 2series it will be a big change for BMW.
