I know. The worst is certainly between gear 1 and 2. But keep mind it is an automatic transmission so there's so fast they can shift. I've heard of TCU upgrade but I'm not familiar with the topic. You may want to do a search on this blog.

The upshift lag is more apparent during normal cruising shifts, but during WOT, it seems to upshift faster. Either way, it's not nearly as fast as my previous BMW 335i's ZF21 6AT tranny w/ the paddles...that shifted in just 100ms.

Ya I was just thinking the same thing. The fastest auto shifts I've ever experienced.

I had the problem too. Basically it took long time to downshift 2 gears, like from 7 to 5. I am thinking about TCU tuning.. but still gathering information..I have to say this is the only problem I have with this beast...

I don't know what you guys do during the normal course of the day but for a daily driver its perfect. If you need to shift that quick you should have gotten another car.

My 09 seems to have a little delay also. I've also just been reading and gathering information on the ECU and TCU tuning since I joined the forum. Need to get to the track and get some base line runs in so I can get rolling, as this is the first vehicle I've owned more than a month with out modding.

hmm, I am thinking about calling Kleemann to get more infor on TCU and ECU since they have really good reputation around here. I wondered if someone else did it already. I will be surprised if no one hasn't asked about the lag issue yet. It's kind of annoying. just me...

He says that the Kleemann tune does absolutely nothing to change or alter this. What others have written about the transmission feel has nothing to do with the shift points having been changed. Perhaps it is just that extra power from the tune that eludes to that feeling.

The whole TCU tuning has become a very controversial issue since the emergence of MHP and their claims. You should do a lot of research before taking any steps regarding TCU tuning.
Regarding the shifting, unfortunately, most AMGs have this shift delay. What makes matters worse is that the delay is actually variable. One time, the delay maybe 0.005 seconds while other times, it maybe 0.01 seconds. This makes it incredibly hard to learn how to time it. In general, best results are usually achieved via sport mode right after aggressive re-adaptations.

Its still the best true auto tranny i ve driven. It actually works very well when you put it in Comfort or Sport on the road. Where as stuff like the SMGIII's auto is simply unbearable on the street. New technologies like bmw's DCT or PDK are much better but I don't think any of these are as good when in full auto mode as the C63's tranny. (DCT at least isn't as good in auto not sure about PDK)
Now the 335's ZF tranny is a really good unit that probably shift slightly faster than the tranny in C63 but I don't think it rev match as well and sport mode isn't as good.
As of now theres always a tradeoff between comfort and shiftspeed.(again mabye not the PDK)
