Transmission Problem!
Took a nice drive up to Mississipi sports car roads. Back in Louisiana for a pit stop, the car went crazy - in drive, it was in neutral. I was about to call AAA, when I found that if I used manual, the car would work, so I made it home. THIS SUCKS! 425 miles - I only got 50 on the last one.
This is my second 55, the other one was replaced.

What are you doing to the cars? Now that you mention the transmission, are you playin the stereo so loud you aren't noticing that you have accidently hit the paddles on the back of the steering wheel (throwing the car into manual) and redlining it til you kill it???

Nope, top down with stereo off and following the break-in guidelines. Get real.

So, its an electronic module that MB outsources to their subcontractor(s) (such as Bosch, or Delphi, etc). MB admits to have not keept tight enough quality control on some of its suppliers, thus, we see some field failures on rare occasions. In an case, its a pretty easy fix. Just tell the dealer your think its the tranny module ECU & they can get a replacement & advise you when to bring it in (I'd recomend getting them to flatbed it to your dealer once they advise the module has arrived
to minimize you being inconvenienced further. They "should" agree to the above diagnoses if your tranny goes into N while you are just driving normally down the road). Good luck,

A similar thing happened to my '05 SLK55. It went into N while I was cruising abt. 30 mph. Engine revved to abt. 4k RPM. It acted funny until I could stop, turn engine off, and restart. No problems since (that was abt. 500 mi. ago when car had 1,500 mi. on it).

Update: Just picked the car up from the dealer. Yes, the electronic module was replaced. They scavenged one from an SL 7-speed still in the crate, then did the SCN program. Everything works fine. I appreciate the quick turnaround - this dealer has been stellar in its service. 
For the record, there was no malfunction display, only the check engine light. The check engine light was off when the car was driven to the dealer, but there was a couple of "clunks" in the transmission at the start of the drive there.
As I have stated before, MBUSA saw fit to replace my first 55 because of a computer failure in the stability systems that could not be resolved. This was after a total of 200 miles, all of which, except for about my 50 miles, were test miles. And the car was in the shop for over six weeks. That car barely reached 70 MPH and never over 4,000 RPM. I never had a chance to load my favorite Rippintons CD which apparently might have put me at risk of misusing the paddles.
For anyone to insinuate that the driver is defective, not the car, is to ignore the fact he/she might be so enamored of this car marque so as not to accept the fact that the vaulted three pointed star might indeed be tarnished by quality problems. This car now is my fifth Mercedes-Benz. Only the last two have had problems.

Besides, your remark begs some questions: Even if there is an excursion to high revs, why should that immediately cause the transmission to fail? Has anyone redlined their car?
Or, say, I'm going down the road at 60 MPH and tap the (yes, ill placed) paddle to suddenly downshift as far as the transmission will allow. Wouldn't I be thrown toward the dash by engine braking and immediately let off the gas? Might even squeal a rear tire? And then I should expect transmission failure? How does anyone get away with doing any track days in this car?

And what do you mean by "kill it"? Should this still necessarily harm the electronic control module? Do you have some evidence of this or are you just making a supposition?
I think you're position is tenuous at best and I still don't appreciate your condescending tone.

Sorry about my condesending tone. I just can't believe you've been thru TWO SLKs!
As for facts ... do you think if you put your car in manual and took off, flooring it and never shifting, car moving, going faster and faster, and doing this to the car again and again, your transmission would be okay???

Your ENGINE, on the other hand, would waste little time before crawling out from under the hood and clubbing you to death with its throttle arm.

Believe me, I suppose M-B also has a hard time believing that I have gone through two SLK's. For the first car, it was an anomally that only one another car in Chicago went through, I am told. And both cars will never be sold to the public. The Jacksonville rep drives my old car now, and has 5,000 miles on it, after repeated trips from technicians from New Jersey worked on it. Again, this is a very rare occurence. So forget the first car.
I am really enjoying this car. Pewter is beatuful, not the brown that I was expecting.
Only positive posts from here on out.

I drive a E55T, SLK55 and 65 Mustang Conv.
If you do not shift the car in manual mode, it will bounce off the redline and upshift, I had this happen a few times in manual mode when I did not hit the paddles quick enough. Wolf
