Hello everyone, today I experienced something strange during my launch control. I was in manual and race mode. The start was good but after that when she went from 1st gear to 2nd gear and up to the third I get slamming every time I go through it. I don't know if the outside temperature (5 degrees Celsius) and the fact that I'm wearing summer tires have anything to do with these slams. I don't know if any of you have ever experienced this before. I drive a 2016 C63s with the 7speed speedshift MCT gearbox. Thank you for your help because I'm very worried about those slaps.
