I was thus very hesitant about risking it again with a ZF box, but have been delighted with my 335D so far. One trick box. No regrets at all.

I read a lot about the 'transmission slam' on when I had my 530d. Fortunately I never experienced it. What I did struggle with was the momentary delay when pulling away from standstill. It seemed that this was in equal parts down to the interface between the transmission and DSC (i.e thinking time) and torque converter delay. It was faster with DSC off altogether, but with 500nm of torque that's not the most practical option all of the time.
To get around it I found that I needed to drop into 'manual' and engage first gear as I decelerated to a stop .. the converter then seemed to be 'locked up' ready to pull away.
Is there any sign of this delay in the new transmission? Hopefully not since the lock up is meant to be much faster.
