2009 Mercedes C350
I'd love to hear positive results on this as well. I'm quite unpleased with the TCU software on my C350. It shifts slow even near redline at WOT, but that's not what bothers me. It's the ridiculous delay when shifting into reverse. 
Do you know how frustrating it is driving around a parking lot with people on your ***, and needing to pull past a parking spot, and reverse into it. When you drive past it and someone pulls right up behind you (impatiently of course) and you shift into reverse and have to wait 5 seconds until your car actually decides to let you back up
I've literally almost gotten hit because my car takes so long to reverse at times. Its quick when you don't need it to be, but when you are in a hurry you could almost make a cup of coffee before it fully engages reverse.
My wife's Charger (also a Mercedes transmission, if that makes a difference) shifted extremely slow on up shifts. We updated her software at the dealer and now it shifts 4x faster and the overall feel is much better. I'd really appreciate an update like this for my C350 Mercedes. Kthanksbuybye
