High rev gear changes make a very loud thump. Same as my E46 with SMG.

The disengagement is fine but reengagement produces a rather disturbing thump and jerk.

Do others experience this or is it abnormal.

It's true and most noticeable when you give WOT on sport+ (shifting logic = 3). They say it's a price to pay for the shortest shifting time.

I heard m4 GTS DCT flash is smoother overall. Just don't know if it would get improved in that area.

I have found the DCT to be a pleasant surprise.....my first 2 pedal track car. On the street it is fine, although not a Lexus , but it does take some time to learn your driving patterns. When pushed to the limit on track it is exceptional.I had a pro driver take me on track and he said it was better than PDK and that in auto mode it was unnecessary to use the paddles.

Are comparable lap times achievable w/o paddles?

I can't imagine anyone wanting a "smoother" DCT...unless you like slushies. The DCT is crisp and pronounced driven hard, not at all barbaric like an SMG. DCT is a beautiful thing even in stock programming...you just gotta warm her up first. Smooth on and off throttle until she's warmed up and then she's like a hot knife through butter.

mine doesn't thunk--maybe yours has the diff recall (where the bolts come loose)?

Not my experience at all. I'd say it is about 3/4 of the SMG feel. I've driven the AUDI/VW DSG and the PDK. Neither are as violent as the DCT.

Does someone have the official info on this. I need to determine if my car is eligible.

[BruceM]

In which modes? All of them, or does it vary?

Jade Buford drove it a few sessions at Road Atlanta and Peter Argetsinger drove it several sessions at Sebring....both said the auto mode was damn near perfect. They felt that for a DE driver there is no gain in using the paddles.

[MZWIE]

I would agree with that statement. The only thing is that in D mode you have to "kick it" to downshift. So in those cases the paddles work better.

In daily-driving auto, I typically only use the paddles to upshift. The car tends to get "stuck" in low gear after accelerating. Too obnoxious, esp around town, if all you wanted was a quick burst of acceleration.

On the positive side, the DCT selects the highest gear while cruising on the highway in sport. BMW's regular AT won't do that, presumably because it's too slow to react to power demand.

DCT is not as smooth as DSG or PDK. But I wouldn't call it harsh either. In sport+, there is a little bit of a jerk during high rev shifting.

I think the M2 DCT is too smooth. I had a 135is N55 with DCT and that trans was very crisp on its shifts in sport mode. Actually it was very telepathic and I ended up not shifting manually much at all and definitely not on the track. It did a better job than me selecting the right gears at the right time on the track. I was disappointed in the softness of the M2 DCT shifts and it does not do a good job of selecting the right gears. I was offered the first allocation M2 from my dealer last February and it happened to be DCT. I preferred manual but the DCT in my 135is was so good I decided to take it in the M2. I was and am still disappointed at how soft and sluggish it is in comparison. Don't get me wrong. It's still good and in manual mode is pretty good. But it is definitely not as good as the N55 135is was. If you look at the parts they are the same so it's 'just' the software controlling it. I even went to the dealer and asked them to load the 135is software into it. They checked with Germany and were told it was incompatible.

I can relate to that. The stupid thing won't upshift even if you completely go off gas. I get it it's preparing itself in case you get on gas again, but come on, it guesses wrong more often than not.

[DivideBYZero]

It's soft as balls in Comfort. In fact, it's too soft in D.

[MZWIE]

In comfort it is meant to be soft as cotton. In fact I was amazed on how smooth it is. I was only referring to SPORT+ shifts.
