Slow gearbox

[Deexo]

Hello, I'm Fabrizio from Italy

Does anyone know why my A-Class 180d with 8G-DCT is slow at kick off?
Whenever I release the foot from the brake the car obviously starts moving, but it's very slow.. sometimes it's so slow that I have to give it a little press on the accelerator risking to crash in a wall, especially while parking in enclosed spaces..
I had a gearbox change about 3 months ago in warranty for a vibration and a noise that i had while starting in 1st and reverse gear, but even with the broken gearbox i never had this issue..
What could I do?

Brakes binding slightly , not all automatics creep under tick over revs.

I mean the car movement after releasing the brake, in other automatics (even other 8G-DCT like friend's car) starts moving normally, not that fast and not that slow, just fine.. while mine is very slow, sometimes not even hitting 1-2 km/h, making the park even more difficult.
Also sometimes seems like it doesn't have enough strenght.

I know , hence my reply. It's obviously the new gearbox then, if not binding brakes.
