Sounds like you're having problems with the kickdown from 2nd to 1st. DS makes the tranny go down to 1st. D usually starts in 2nd.

No offense taken at all. Thanks for chiming in. This is my first BMW, and I know BMW has great brakes. But I have a couple other 2 seater sports cars with great brakes that I also drive and whenever I get back on my BMW I do have to adjust my brake pressure. I would actually say that the BMW brakes are over boosted initially, rather than linear. But anyway back to the problem. Both times I took the technician out with me to show what I was talking about and they felt it too, and said they will look at it. So it is not because I am not used to BMW brakes. They thought it was down shifting hard at first, but I do not think it is transmission related any more since when I manually downshift it still does it and it looks like another gentleman has the same issue with the 6MT. Plus both time they did something with the computer and reset something, then the cars comes to a smooth stop, but then the problem appears again within a day. This must be a software problem.

I had the same problem. Always felt like I lunged just before a complete stop. Another problem I had was when the engine was cold and when I went to accelerate, the peddle was very touchy. That is, when I would go from a stop, the car would really snap forward. I took it in and they disabled the stop assist, but it still did it. Two weeks later, I had a new transmission. Issue was resolved.

OK, my car is finally fixed, after taking it for the third time. PUMA case was reopened and they did the fix. The car no longer bumps right before the stops.
According to the Invoice, this is what they did: 1. Replacement of Mechatronic Valve Body 2. Replace Trans Fluid 3. Replace Trany Pan 4. Coded and programmed new Mechatronics

It's the Neutral Idle Control. The first step in SIB, is to update the software to smooth out the bump feeling, second step if that doesn't work is to deactivate the NIC feature completely. They just did that to mine last week. The Car is running silk smooth now.

BTW, it still does have that slight transition where I think the rear brake calipers let go right before the complete stop (I am assuming that is what I feel. It could be the down shifting of the gears?). However, that does not feel like a jerk and it is mostly smooth transition. I think that one is normal?

Got mine fixed
I replaced the transmission mechatronics sleeve, seal adapter, changed the fluid and reset the adaptive values all at the same time a few weeks ago. Since then, I have only put a couple hundred miles on my car, but it seems to have fixed the problem. Before I did this, the hard shift issue would re-surface after approximately 20-50 miles. So far, so good. Price wise, it was only a couple of hundred dollars, and the VAST majority of that was in the new transmission pan/filter and oil. The mechatronics sleeve and seal adapter were less than $20 combined, so if you re-use your oil and pan, you can fix this yourself for about $20.
