Are all MB Auto's like this?!?
So I went in for Service A today and they gave me an '03 240 with 3,000 miles on the car...basic car with auto..no other options that I can see.
Anyway, since I have a stick I decided to try their auto-stick thing. I put it into 1st and drive...the car auto shifted to second around red-line. Do all auto's do this? If so, whats the point if you can't hold the car at a certain gear? The car kept switching gears when I didn't want it to. I got so tired of 'fighting' the car I just put it in 'D'.
Thanks,
Erik

At red line the automatic will automatically up-shift to prevent damage to the engine. An MB automatic transmission I think is one of the smoothest and best out there. If you were driving and then held the shift knob to the left for a few seconds, the car would down-shift into the lowest possible gear for the speed you are going (for more sport driving). Other than doing that I think that it is slow to up shift when using it in touch mode. One of my cars is the 6 spd and the other is the auto. I love driving stick, but next to that I think the MB auto is the best, but forget driving it in touch shift mode

I understand it stoping the fuel at rev-limit, but i don't understand it shifting...maybe its just me, but then I really don't see the point.
I agree it is very smooth.

I do have one question about the delay of the touchshift upshifts. I rem in my A4 tiptronic I can guess the delay of shift to about 300rpm (+ or - 50rpm), meaning that if i wanted to shift at 5300rpm i would do it at 5000rpm resulting in about 5300rpm shifts. After looking at the dyno charts of my pullied car ideally i would want to shift at about 5700rpm however if i leave in full automatic it shift at either 6000rpm or sometime even 6200rpm. Does anyone know whats the delay/discrepency of the touchshift tranny so that I can get more precise 5700rpm when u're pushing full-throttle? Thanks.

My C200K auto box WILL NOT upshift automatically by itself if I manually tap the gear lever to 1, the car was over revved a few times (about 500rpms or so). I think it only applies to the car which has “tippshift” feature. In Australia C200K sedans don’t have it.
Good thing is that I can treat it like manual where I can revved it all the way to redline without upshifting, bad thing is over revved like my friend did to my car as hes not accustomed to the car![Frown](https://mbworld.org/forums/images/smilies/frown.gif)
I normally manually upshift about 5500rpms resulting in about 6000rpm upshift if I drive aggressively.

queston about toughmode
i have an auto, but when i put the gear in 3rd gear, and car stopped. it will still go from 1st gear and slowly shift to 2nd. and to 3rd...why is it like that?
and for the auto mode, i think my 240 is slow in auto shift. something it will wait til 4-5k rev to shift..is it normal to all the 240..i know 320 won't do that...??

Maybe it's smooth - but it just doesn't work very well with our wheezy engines. Driving around in D the transmission wants to go to 3rd or even 4th gear while going 30-35 mph!? When I had to pass someone, even when clicking the button (under accelerator) it still took a good 2-3 seconds before the car's systems agreed and shifted down.
This was unnaceptable. In an emergency situation you have to be out of the way then and there.
How did I fix this transmission problem? Simple, traded it in for a stick! I can't believe what a difference the stick makes. Hold your gears as long as you want, keep it there. Life is good again.

why would you want the engine to cut off the gas when it can upshift? Give me an example when you have to keep it in the redline all the time.
if the engine redlines and shifts, it means that you have enough distance to upshift and go faster. just downshift when you reach the end of the straight.
for noodlesoup, because it's an AUTO. BMW's SMG II will also put you in first when you stop. I think all the new MB has transmission that will learn from your daily driving style. You can upshift by tapping right if you want to shift early.
