7G drivers.. Comfort or Standard?

I just had the chance to drive my parents E350 this weekend, and I felt the 7G was not very smooth at all when I first got in the car. As it shifts, the revs shot up a bit before the next gear engages, causing a slight jerk when it shifts. I thought there was something wrong with the gearbox. Then I tried to switch to comfort mode to see if situation is improved, and the shifts became much much better, but it shifts way too early for my liking.

I was wondering if you guys have the same problem in standard mode. I prefered the shifting points in standard mode, but couldn't stand that it wasn't as smooth in Standard mode. Perhaps i should take this to the dealer for them to have a look. My parents aren't really car people so they don't really notice these things. On the other hand, coming from a W124 E320, they are absolutely happy with this new car.

The TCU adjust to the way the person drives ,if you dont drive it every day but someone else it will take some time for it to adjust.

It took me and my mom about 20 minutes at the wheel to figure out how to apply gas to avoid that kind of a start. The C works fine (and they tell you to use it during break-in for 1000 miles).. but you'll loose acceleration performance if you always use it. Stick to S for a while and you'll get used to it.

After 1800 miles the TCM has not adjusted to my driving style on my 2005 E500.
C mode does shift better allthough too early and starts in a higher gear.
S mode is definately the quickest mode.. I got a 13.89 @ 102.5 in the 1/4 by letting it shift by itself but it's very quirky driving it around.
Took some fooling around with the traction control (which I could never really defeat 100%).
5.01 seconds 0-60.
Sometimes it thinks too long as to what gear to use when downshifting and occasionally it just plain picks the wrong gear.
The 1-2 upshift at med/high throttle is annoying.

Manual mode is just too slow to react and using it really slows the car down. It's fun to play with though.

I manufactuer automotive calibration equipment for a living and MB can surely use some lessons on trasnmission shift scheduling and torque converter strategies.
Soon as I figure out how to reprogram the car myself, it's going to get the tranny stuff fixed right.

This reply may not apply but...

I just picked up my car on Friday and drove it aroun 400mi this weekend (that include the P/U from adjoining state). The car has been an absolute dream to drive. Especially in comparision to my wife's '02 ML. The shifts are smooth , almost to the point of not being noticeable. The downshifts on the freeway such as for passing are quick and responsive. I can't say that I have any complaints at all about the transmission.

On a side note, doesn't switching to "comfort" just toggle the transmission to start in 2nd gear when accelerating from a stop? My apologies if I am way off here but I haven't made it all the way through the 500p operations manual...

It also will shift earlier.. This is why on the 2005 model they suggested using this during break-in.
