Hi, I've only experienced the transmission slam from your list.
The first thig I did was I tried the 25 seconds reset. Here's a link: https://5series.net/forums/index.php?showtopic=78578
When that did not work, I went to dealer and told them that the transmission was harsh when shifting. They could not duplicate, but updated the software that supposedly would fix the problem. I got the car back and the problem was still there.
By that time, I was reading more and more about this, right on this forum, and learned that the correct term to use was "slam."
Made another appointment and asked them to have the shop foreman drive the car. He could not duplicate the problem, but when I described the "slam" he said he knew exactly what to look for and that he was going to perform some mechanical checks to confirm his suspicions. Later I get the call that his mechanical check came back positive and that they were going to replace my transmission under warranty.
I am happy to report that after more than 6 months, my new transmission has no slam and it still is velvety smooth. Hope you can get your resolved. G/L

Just to be clear as I am a newbie. If I'm experiencing the "slam" when coming to a stop, the 25 second reser could possibly fix that issue? My 530i is a 2007 CPO and when I told my SA about this issue he told me there was not a fix for this. Sounds like I need to do more digging.

Just wanted to give an update on my transmission issue. I tried the 25 second reset and no changes. Today I dropped off my 07 530i at BMW of Annapolis and after they checked it out they told me that they have to talk to the BMW engineers to see what the proper fix is for the "slam" on the trans when coming to a stop. ONe other thing I noticed is that even in manual mode when at a complete stop the trans would jerk when downshifting from 2nd to 1st. Anyways, car is staying at the dealer until they talk to the engineers (in Germany apparently). I'll keep you guys posted on the details. Prior to this I had the transpan gasket/mechtronic sleeve replaced due to a leak and this did not fix the issue. I did get a loaner 2008 328i which is fun to drive around, but I do miss the smoothness and roominess of my 530. I'm happy with the service at BMW of Annapolis...got a good SA.

Ask for the software update. Now I am dealing with dashboard popping (1 vist already), smoke coming from the front grill (2 visits, 2 cooling pressure tested) and suspension bottom out sound in the cold morning.

My Ride: SOLD...Jet Black 2008 550i M Sport with SAT, black interior. RPI exhaust and air scoop, 35% huper optik tint all around, CF roundels, flat black kidneys, Springfield Armory XD-40 jet black in glove box, charcoal filter removed.
Hey, I did. Nothing wrong with the suspension at all.
Regarding the tranny slam, they couldn't reproduce it and said everything looked fine. They did find a fault in the system referring to a voltage regulator off the battery, i forget the part name now. they replace that part under warranty and told me everything else was ok.
I still have a slight tranny slam issue at times, but i'm thinking its just the way it's gonna be. I pretty much garaged the car for the winter now, so when it heats up outside again I'll take it out for some long trips and see how it goes.
Thanks for asking!

Not sure if the drop in temperature has anything to do with the transmission, but 4 days after getting my car back from the dealer and getting the trans checked, the "slam" has returned when coming to a stop. all was good, but now not sure. I'll monitor it for a few more days and see what's going on. Hate to have to go back to the dealer, but this is not something I want to accept as normal. I don't like the jerking when slowing down to a stop. This is getting a bit annoying. :thumbsdown:
