... Has the following ever happened to anybody: the AT downshifts by itself a split-second before you go to downshift. So it shifts, then you shift a second later, and you end up 2 gears lower instead of just one. I never did it, but I hope I don't since a double-downshift could be stressful on the transmission. I would imagine that it wouldn't let you anyway....
I've only noticed the 5AT shifting to 4th from SSM 5th when I'm doing about 35 - 40 MPH, IIRC.
Mercedes Benz are really nice looking cars, but I'm starting to think that they're stupid now. There's so much technology that doesn't work neatly and becomes the opposite of what the technology was originally intended for. I bet the British guys from Top Gear would really rip on it... kinda like the BMW 5-series. I'm glad I didn't get the 2007 c280 last summer when I was looking for a car. It doesn't even have a sportshift. Honestly, after seeing the infinity G, driving the TSX, seeing my neighbors Mazda 6 with AWD, seeing the new eclipse, and considering our economy, I'm starting the realize Japanese cars are the way to go. In my book, German cars are out.
I mean the shiftknob sorry. MB shiftknob action in manual gate does not shift like TSX. A little sideway nod will shift up/down, once you got used to the TSX M mode, you will probably shift 1+ gear (up/down) on the MB, because when you hold it for more than 0.5-1sec, it will auto downshift to the most aggressive possible gear or vice versa.

Got it. A coworker just got a C350, and wondered what the "wiggle" position was for. I told her to try it peeling out from childcare after picking up her boy....
As for the Nissan trannys, they're using CVTs in the Maxima and the Altima. As a general rule, I can't stand CVTs. I like that act of shifting. And a CVT and near WOT is about the noisiest, cheapest sounding thing I've ever heard. You might as well just put it in neutral and rev the engine. Oh, and if something shears in there, forget it. A single sheared off tooth will turn your CVT into a housing full of ball bearing sized chunks in a matter of minutes. I've seen it happen. Pulled a CVT off a Saturn and the biggest piece left inside it was smaller than a dime. Sounded like a moraca. Although, Dad did say a few years ago he drove an Audi prototype with their 2.0T motor and a CVT. He liked it, said it put you back into the seat and left you there until you took your foot off the gas. Smooth and quiet.
Back on topic.... I like the SS simply because the tranny in D will not go above about 5300 RPMs. I discovered that pretty quickly when I bought the car. Even at WOT, it shifts well before VTEC engagement. Which I guess makes sense. If you want the power, you probably want the control too. And if you can't control it, you shouldn't have the power to begin with.

... or find an uphill freeway on-ramp where you can achieve lift-off. I've read elsewhere that the ECM "learns" the driver's driving behavior and adjusts the shift points. This can be reset by disconnecting the battery for 20-30 seconds (be sure to have your radio and nav unlock codes).
[1] Did it earlier this week in fact. Shifted from 2nd to 3rd at about 6800.
Ha! You said uphill! I live in Florida.
The only hills here are artificial and smell like.....well you know what I'm talking about.
And most electronic auto trannys learn the driver's habits and shift accordingly. Generally, I drive like a granny. Gas is way too pricey to be aggressive. The SS is there when I need a little more juice, so I don't worry about it too much. And bumping it left and down is pretty much second nature at this point.

The primary purpose of gears is to match the RPM band of the engine to the speed range of the vehicle. While some cars that had high torque were produced with only two gears, it is a very inefficient arrangement. For those cars without much torque, the engine would be overloaded and would stall. It would be like driving the auto TSX in 4th gear at all times -- a little slow on pickup when the light turned green, I would say.

Yes it will
