Hi
I’ve recently bought a W205 C200 diesel sport automatic and I’ve noticed a few gearbox quirks.

first is that on cold days the shifting is jerky from 2nd to 3rd (going to try the adaptive reset mentioned in another thread)

the second issue is a bit strange. I’ve noticed when driving slowly it will not shift to 1st gear unless I physically stop. So this results in me arriving at a roundabout, slowing down to 1mph and then pulling off in 2nd. This just doesn’t seem right? If I stop it immediately goes to 1st then changes to 2nd normally.

any ideas?

Not sure about the first one.

the first gear “issue” is completely normal and just how it’s designed to operate. First gear is only for getting off the line when you’ve come to a full stop.

This transmission is quirky and can feel clunky at times. I did the reset and it seemed to help a bit with the 2 to 3 upshift. It's incrementally improved over time even long after the reset. I think part of it is just learning what throttle input yields the best shifts, which over time is conditioned into muscle memory. It's definitely not the smoothest transmission and is somewhat disappointing coming from MB. Our biggest gripe is the 7 to 5 downshift, it tends to be really touchy.

As for holding 2nd ger until stop, that's normal.
