Transmission acting strange
I was driving this morning approx 30mph and when I pushed the accelerator the car just reved up and wouldn't move. It seem to have slipped and couldn't jump into gear. I put the car in neutral and then back into drive and it caught itself and seemed fine therafter. Does anyone know what could have caused this occurance?

I had one similar experience about four months ago which also started at about 30 MPH. I was on a busy street, Century Blvd, returning from a drop off at LAX. It revved but seemed like it was in first gear and was putting out some power. Attempting a manual shift had no effect on it. I immediately pulled off the road and turned the car off. I then let it sit for about thirty seconds, started it up and everything was fine.
I called by MB Service Manager who I've known for years, and he said that what I did was what you should to and that I could bring it in for a computer check but that it probably wouldn't recur. Since then it's never happened again, and I"ve had the car in for it's annual and last free check.
If you punch the gas abruptly and release it fast the SA says this may occur; however, I'm not going to try to cause it to happen again as car has ran fine for several thousand miles since that happened. I think it could be a software glitch in the automatic transmission electronic control box, but that's a SWAG.

Transmission Strange, I think not!
Look on WikiPedia, In the reliability section the second bullet point states that the trani is not reliable.
I had the same problem on my E5. It turns out it was the valve control body??? Whatever that is, it was $2400 to fix. MB knows what the problem is and they don't want to pay for it. It is a known issue. If wiki knows then MB knows. Look in the manual, they built a limp home feature for when this happens.

Transmisison ECU reset?
Anyone have a link to to a the thread in this forum on a step by step on reseting the ECU unit that "learns" your style of driving and adapts the trans to your style. It was somthing to do with putting key in ignition, while holding down the gas pedal floored? There were multiple other steps but I don't remember them. I think it was posted on here about 1 -1.5 years ago.

Hello Blue,
I found the thread your looking for a couple of weeks ago. Couple of the guys with E500's were resetting there autobox memorys. I did it on my E280cdi couple of weeks ago but i can't remember exactly what the procedure was but i'll do my best to list it.
1. Insert key into ignition and turn to the on position (the one before the glow plug) .
2.Push accelerator down within 5secs and keep it there for about 15secs and then turn the key to off (do not pull out key) and only then release the accelerator.
3.Leave key inserted at the off position for 2mins before attempting to drive.
I had a problem with my 7g box where the vehicle refused to kickdown (not turbo lag!) and since i performed this procedure it has been fine.https://mbworld.org/forums/images/smilies/thumbsup.gif
