Sounds like it's just downshifting a tad early.

 

Happened to me today as well. I was driving downtown at a pretty slow rate probably around 10mph or less and the car in front turns on turn signal I let foot off gas and go to brake and the transmission downshifts and makes said clunk. I don't think that it is a problem at least I hope it is not. I just think maybe we are a little paranoid about this new tranny.

 

I hear a clunk once in a while when come to a stop in SPORT mode, but the clunk is very gentle and the sound happens much less often (or I don't even detect it) in Normal mode.

 

This just happened today and was the 2nd time. For me both times happened after exiting a turn, pretty much same as last time : was in auto mode 4th gear, let go gas as the light was green, make a turn without pressing gas, then after exiting the turn (starting to go straight) press gas pedal lightly and it did that. This time it didn't make a loud sound but the "shock" was huge.

Has anyone talked to the dealership about this? I'm a bit hesitating in taking my car to the dealership because it's hard to repro so I don't want them to take my car for some crazy rides trying to repro this.

 

Just happened to me on my way home yesterday. I was turning left in 3rd gear i believe, and happened just as I was straightening out . I wasnt on the gas as it was a playground zone. From what i can tell its just a really hard downshift.

 

bump - went to check out an MR today at a dealer. I didn't personally drive it but the salesman did and heard a loud clunk from the tranny while driving slow. I think this is normal for DCT but just wanted to confirm. I know this is a known issue with the GTRs.

 

Havent noticed it yet

 

I have never had this. When I'm back in town in two weeks I will see if I can do it.

 

It's the clutch...it disengages in normal mode when you are coasting/braking to a stop. Step on the gas suddenly again and it'll re-engage creating the sudden lurch/thunk. If you want to reproduce this, just drive up to 60km or something then gently brake in normal...once your speed is below 10km/h suddenly step on the accelerator and you'll be guaranteed to get the clunk. I find it does this far less in Sport mode since it'll revmatch instead of disengage.
