Brakes have friction material that is designed to wear out.
Transmissions have friction material that is designed to wear out.
Brakes cost about $ 100.
Transmissions cost about $ 7,000.
Why would anyone use a transmission to stop the car?
Using the transmission in 2nd or 3rd gear to decend a long grade is useful in that it limits your speed, whilst not overheating your brakes.
Shifting into neutral while the wheels are turning is not safe, and can possibly interfere with proper lubrication and cooling of the transmission. Most transmission designs have the oil pump on the input shaft. If your engine is at idle, the pump is producing minimal pressure, but the bearing surfaces on the output shaft are very busy, and require the increased lubrication and heat removal that a faster pump speed will produce.
Tiptronic transmissions are only found in Porsche cars. Mercedes-Benz cars have a Shiftronic transmission because those dogs at Porsche trademarked the name first.

I used to coast all the time in my 87 cougar and then kick it back into drive but that damaged my tranny to the point where I no longer had 4th gear. I remember I had to drive for nearly 2 years without going on I-95 because I couldn't go over 43 MPH and I was too broke to fix it.

I honestly do not like MBs steptronic. For one, it doesnt rev match when you downshift and two, its slow! I found it to really only be useful in aggressive driving where I threshold brake into a turn, I then downshift and use very little engine braking, and I exit in the right gear. But thankfully I only have to deal with that in loaners!

The DSG shifts a lot faster - this is the best compromise out there - full automatic if you want it, and real manual control if that's what you want.
(Sorry, but I too still get a tic whenever the term "Tiptronic" is used to describe any transmission with some kind of manual override. It is indeed a copyrighted name by the VW group [Porsche, VW, Audi]. As I mentioned in another post, this is kind of like using the term "kleenex" to refer to a tissue - probably unavoidable, but still...)
I have to add my caution that shifting to neutral and back into gear at speed with any torque-converter automatic is not going to be good for the life of the transmission.

I hate threads like this. Its a friggen slushbox...who cares if its slaptronic. Take off your skirts and learn to drive manual transmission cars.

haha you tell them outland! naw but seriously, i think because either, 1. somebody other then themselves (mother, g/f, etc.) has to drive the car or 2. they just live in areas with messed up traffic, which is why you can get best of both worlds (or pretty close) with the shiftronic.
back to the subject, i'm not sure about the engine breaking, but shifting to neutral on an auto? it just doesn't seem to nice for the car.

I had a rental caddy when I was in Charlotte, and I noticed on that car that when coasting it went into neutral. The revs dropped down to like 700 rpm when doing 60mph, either that or it's some tall OD

When you reach 50 you'll realize how stupid your attitude is everytime you enter one of these threads to take a swing at AT drivers. In the meantime, get over it. Stop bashing others who choose to buy an MB the way that MB sells them to 95% of US buyers. If you hate these automatic transmission threads so much, then stop reading them and keep your opinion to yourself rather than injecting your off-topic remarks. {moderator hat back on}

all of my friends have thier cars on stick (maxima, A4, WRX STI)....but they dont drive down the va vyck to school everyday ...itd be a pain in the ***...plus whenever my dads POS ML breaks down hes gotta drive my car and stick cars **** him off...regardless MB has to step the tranny game up...if not more availability of manny trannys...why not work on something more of a DSG or a CVT...both are IMO better than what MB has available...especially after reading that the new 7 speed cant pick a gear

I drove a stick shift in various sports cars from 1974-2001, probably long before your daddy slipped it to your mommy.
Somewhere along the line, I outgrew the infantile opinion that "real men" drove manual shift cars.
Now, if you buy the automatic, realize that its not going to do what you want it to all the time, that's why you bought it. You bought it to do the thinking, and the work for you.
So I drive a "slaptronic" today.
My choice, and those like-minded don't give a flying rat's *** about your narrow-minded comments.

Did you trade the GTI in on the MB?

Coasting is good when you're going downhill and don't need your foot on the gas pedal or when you want to roll to a slow stop. Other than that, you'll be one of those drivers that I see all the time....one moment, he's slow as ever and then another moment, he's hugging my a**s already. Engine braking is good when you're going down hill too fast (steep decline) and you don't want to constantly step on your brake pedal. It's also good when you're constantly going down hill....like coming down from a mountain at Yosemite national park.
(OFF TOPIC): Regarding those comments by "outland", many people choose automatics simply because of different reasons. But from my own personal experience, it goes like this: First, autos have been known to last longer than manuals. Second, it is easier and more relaxing to drive in heavy traffic hours. Third, it's almost as fuel efficient as a stick if you don't have lead foot. But just by observing how most americans drive, I would say about >90% of them have lead foot. Fourth, not everyone can drive sticks. My mother used to tell me....if your car is a stick, it means you're stingy because you don't want us old folks driving it. And fifth, insurance is cheaper for autos. Why? because they know that stick cars will break down faster and in general, those who drives sticks are more wild than those who drives autos (insurance's point of view). This dumb rule also applies to a RED color car compared to a WHITE color car.
Driving an auto doesn't mean we have to wear skirts! It's a matter of preferences. I drive both because sometimes I want to be a little on the wild side (manual) but sometimes, I want to be down to earth (auto).

Thank god my car is white....I would coast all the time when i was driving upstate and the highway was going downhill...It gave me a bit more fuel economy too...and engine braking I would use to slow down before coming to a stop at a light...not insane downshifts but revs would reach 4K or so everytime I downshift...the question isnt in the use but wether or not it damages the car...after reading what people said initially I havent even touched the whatever-tronic...Im scared that after a summer of abusing the tranny its going to die on me in the winter

The comment that you seem most upset about was directed at the SMG/DSG posting. Have any of you guys driven an SMG equipped car? Its awful. Totally ruins the car. The system was so slow to respond, and so jerky when you shifted, it would make you clench you stomach muscles each time the car changed gears. I haven't been in a DSG Audi yet, but I don't think I like it anybetter.

Sorry to go off topic a little, but is it me or does the C230 have tons of engine braking? I just noticed quite a bit of it when I was driving it.
Yes, I agree brake pads are hceaper than transmission. Also the seq. shift stinks, the tranny shifts like a grandma #1, so you can never get the gear you want at the time you need it. Also it isnt truely a standard because if you try to run the car in 3 at 2000RPM, it will downshift for you. Remember 2 means 1-2, 3 means 1-2-3, etc
