Yes, I did notice shifting manually eliminates the 1500 jerk. I use Tiptronic a lot more often now because I hate the loss of power with how the C32 rides around in 5th gear even going 40MPH. To accelerate I'm boosting 10 PSI in 5th. I can prevent any boosting, and still have great acceleration holding gears in manual.

Dontbanme: I have exactly the same problem as you. I'm sick of the lag or jerkiness below 2000rpm. I posted something to that effect earlier too. I've done quite a bit of research the past few hours and found that it could be related to a faulty throttle position sensor, which will cost around $300 for a new part. Alteranatively, there is this thing called sprintbooster, which will help to eliminate that lag and allow the downshift much quicker. I'm contemplating getting one.

After reading about 95% positive comments about the sprintbooster, I've decided to get one. I'm hoping that it will bring more enjoyment to the C32. The lag really p*sses me off. Unlike the CLK55, she just goes whenever I need her to shift down. $300 is not a lot of money to throw at a problem. Let us know how you go with the fluid changes etc.

C32s tend to have this issue and i do not think there is a way to fix this except by driving "aggressively"! :-)
I had the fluid changed, re-adapt, CPS change and no real difference. To be specific, the fluid change made the shifts appear smoother, but the jerk was still there the same as before. Re-adapt made the jerk less obvious, but it came back after a week or so.
S or W made no difference whatsoever to the jerk. accelerating harder than usual made the jerk seem to go away, but i am guessing that the harder shifts just hid the feeling of the jerk.
The c55 is totally different. No jerk, C,S and M are all very different modes and the car is in general alot "smoother" in all areas. I will say my previous C32 felt faster than my current C55 though. Just my opinions so hopefully no C32 vs C55 aggro. :-)

I tend to agree with this statement, to unlearn the adaptive transmission so to speak. Today, I drove the 32 a lot harder than I have been since I picked her up a couple of months ago and have noticed that the downshift is a lot quicker. This is with the shift in D and sometimes manually through the gears. It's still not quite there but it's better. I plan to drive it hard for the rest of the week and see if it can be more of a permanent thing. When the rev picks up, the 32 sounds great and feels very quick.
