GLC 63 shfit hard from first gear to 2nd
I accelerated to 5000rpm in the 1st gear and shift it to 2nd
and there was a huge jerk back when I shift it
I think this is this not normal right?
only 5000 miles
Brand new glc63
should I bring it back for inspection?
and yes the car is warm up already

It even happens in lower RPMs. It is so noticeable clunk, that I only do hard acceleration from 2nd to higher gears in manual mode...
Does anybody know why it could be?

Did everyone just accept that this is how it’s supposed to be? The 1-2 manual shift in sport+ feels like the transmission fell out of the bottom of the car. The rest of the gears are completely smooth. I had my fluid changed just to be sure and it’s the same. The weird thing is that one out of every four or so shifts, the 1-2 is very smooth (still fast). If the car is built for it and can handle it then great. The problem is that once you tune the engine it’s much harsher still (due to the extra torque). I’m just worried about longevity. I wonder if any tuners can soften this shift with a tcu tune

Likely due to the Tires. As crazy as it sounds.
I posted about this a year ago & got no reply's. I installed M-PS4's and like magic no more clunk in the right rear on hard accel. (Tuned to 625HP)
If running all season hard compound rubber i believe the wheel is spinning a bit & the tranny is catching. I would get this occurring between gears 1-2 & 2-3.
Now that a few more people are noticing this, is it coming from right rear primarily?
No more spinning all 4 wheels on launch & no more horrific clunk during the 1st few gears.

Edit: I’m still having rough 1-2 shifting, but not as bad. I think it is traction related

Once you learn this about your car, you will alter how you engage the ignition. Your foot will feel this dance and the 2 of you will fall in love with one another. Yes, you gotta take her on a few dates first, allow her to lead, feel her teach you, then she’ll let you slide into her silky stuff.
