Gearbox problem
Where is the 7th shift , or is that normal
Thanks in advance
Your car is normal. If your using D, it will be like you said (D1-D6). But if you use M mode, then it will display 1-7 gears.
I try mine to (c250 coupe 7G tronic) and it the same like you did.
So 7G-tronic is 7speed + 1 reverse gear.
Hope this will answer the right way

It's all explained in the owner's manual. Read through it.

If you want to use 7th gear, you have to switch to M mode. The button is near the shiftknob. You can change it to D, S n M. When you switch to M mode, the cluster will change. And display 1-7. Then you can use the 1st till 7th gear.
Why you want to use 7th gear? Cause using 7th gear you have to speed your car.
Mine's a bit older, so it may be slightly different, but here is what it says:

So, in simple terms:
D = allow the trans to use gears 1-7
D6 = allow the trans to use gears 1-6 only
D5 = allow the trans to use gears 1-5 only
D4 = allow the trans to use gears 1-4 only
D3 = allow the trans to use gears 1-3 only
D2 = allow the trans to use gears 1-2 only
D1 = allow the trans to use gear 1 only
I will never see D7 on manual mode
If you're not sure if you really have 7 gears, press the pedal to the metal and count gear changes

PS : the 7g tronic has 2 reverse gears, believe it or not : http://en.wikipedia.org/wiki/Mercede...c_transmission
