I had this happen on my Mercedes Sprinter(5 speed automatic) a few months ago. It had the incorrect gear ratio code. Took it to the dealer(warranty, had like 2,000 miles on it), they replaced a trans cooler line seal, and topped off the fluid. The SM said the fluid was slightly low, but we're talking less than half a quart. It doesn't take much, and if the fluid is sloshing(especially during acceleration, braking, turning, hills, etc... it can pop into limp mode.
Also, PPI doesn't mean squat. Do you think all of the techs REALLY check everything over? I'd be surprised if they even took the time to throw a dipstick in there and check the fluid level and condition.

Wow...I guess I feel better now that I see I'm not the only one. I was about to faint when it happened...lolll
I get the "implausible gear ratio" code....I've gotten it before when I first bought my car. I've heard it's the first sign on failing tranny but I got this code a year ago and the tranny still rocks.
As for the fluid, I changed it out about 6-8 months ago. Maybe it's a good time for another change?

It would happen to my old CL600 with Renntech ECU/TCU if the wheels spun too hard for too long. It would kick out of gear before the upshift. I just had to restart the car and it would be good to go. The first time it happened did scare the heck out of me.

Except...that it didn't. 
I did a WOT run in 1st gear and the car did a quick burn out. As soon as I got off the throttle it went into neutral and the car would not accelerate. I turned the car off and on again and everything was fine again.
Has this happened to anyone before?

Tranny over torque....limp mode.
Guy with modded S600 up here said he had it daily as he drove his car like an animal.

Yup, just plain ole limp mode I bet. Had it happen in a lower torque gear going around a corner and punching it half way through. Car went BANG into neutral in all gears....pulled it over. Restarted and all better.

Now it is just annoying when you are beating up on M5's
PS: I have learned to live with it as kind of like a fusable link. Better to have it kick into neutral than break the tranny or rear end, IMHO.
