Dropping Gears?
Greetings!
I have a 2013 C63 with a little less than 11k miles.
About every 7th time I drive the car it goes from comfort automatic to Manual (D2) and revs up all the way to 5-6 RPM.
The only way I can get out of it is if I manually shift to get to a safe RPM then pull over put the car in park, then put it back in drive.
I'm afraid to drive it now or go fast because I don't know what will happen. Has this happened to anyone else? If so what was the resolution?
Thank you - JC

Did u pull the down shifter paddles while driving? If I shift while in C, then it'll be stuck in "manual" mode for a bit. What I do is move the car into neutral and back to drive again, and that should solve it.

If you're using the paddles at all when in C, what you're describing is normal. When you use the paddles in C, S or S+, you are telling the car what the highest gear is that you want it to use. Example: if you pull the paddle and downshift to D4, the tranny will happily shift back and forth from D1 (D2 if in C) through D4, but it not go above D4 and once it reaches D4 it will increase revs as you accelerate all the way up to redline. It will not go into D5, D6 or D7 unless you intentionally upshift with the paddle.
Manual is different - you are using the paddles to tell it what gear to be in. It will not shift on it's own unless you come to a stop, and it will then go to 1st on its own.
Look at your display next time this happens. The tranny setting is always shown, and your's will likely still show that you are in C. Just bump your upshift paddle a couple times until it shows D7 and all will be fine.
If your car is really dropping gears by itself - unexpectedly going into M and the "M" symbol is showing up - you have a problem.
