7sp Auto toast on side of road 889 Miles

Wife called me today after getting the car back from the dealer a few hours earlier. She was stranded in a not too good an area right before getting on the freeway only a couple miles from the dealer. Was just reving up and no forward movement. I had her hit the wench and they sent a tow truck. After driving for 8 hours already that day coming back from snowmobiling in Canada pulling a trailer. I did a u turn and headed an hour back north to go get her and my buddies, who was with me, Wife, Oh joy!!! Of course they sent regular wrecker nd not a flat bad as she requested. I got there before the tow and checked the tranny. If I switched between S/C I could get either a forward gear or reverse. The paddle shifters and the manual selector did nothing. You could actually feel the tranny drop into gear when you selected
D but it would just rev up. Not a good sign with only 889 miles. Any other tranny issues out there on this new 7 speed? I said I would never own a Chrysler with an auto (Have 04.5 Dodge Cummins with a 6 speed), Kinda looking like I do. Hope it is just a bad module or computer and not the whole tranny. Or they already have seen the problem. I will keep everyone posted.

PS. Was at the dealer for a detail(Didn't Do a good job the first time/Lack Of time- Was raining and offered deatail at later date-cool by me, New tire and Rim(Damaged before delivery) Sales manager tried to just have it fixed after they told us the were ordering a new rim! Wife called up set. In Candada left a blistering message stating I had never even driven that car and only they had. And if it looked so good after getting fixed they could swap it with another car and have nothing to worry about. I didn't want a brand new car with a dinged rim. I know I would see the repair everytime I washed it and be pissed. They said they would replace it so replace it. Was I at a MB dealer ship or Ted's Used cars. Passanger Seat recline required too much effort to use. No adjustment available thats how they are. Did get to test it back in the shop too fast. And they fixed the poor alignment of the hood on the passangers side with the fender.

I had the same symptoms on my 2004 S500, but after parking the vehicle for about an hour, the problem cleared itself. The next day the dealer picked up the car for a routine service but could not duplicate the transmission problem. The service manager contacted MBUSA and was advised to replace the transmission control module and the valve body. It's been about a month and so far, so good.

Thanks for the update. I am hoping its just the module or comp. and I don't get the we can't duplicate the problem thing. I left her in a dangerous situation blocking the highway on ramp and no power in bad area. I know thinngs happen but I can't tell you the last time I got stranded by a car. Over 15 years ago in a couple of GM rental cars. I rent only overseas cars after that. We will see.

Sure hope the fix isn't too extensive.

How'd they finally end up doing the "tow"? I was thumbing through the owner's manual, and I got a huge headache just looking at the gyrations for towing. The ideal, like you said, is requesting a roll-back/flatbed. But even with that, you have to make sure the 7-speed shifter is in neutral, the theft switch on the shifter console is pushed, the tow hook stored in the tool kit with the "spare" tire needs to be screwed into the bumper with the tire iron so they don't bend or break something trying to lash the vehicle down for transport. Seems like an awful lot to remember under usually stressful conditions of needing a tow in the first place. And heaven help us if we get a flat. Those gyrations (use the special wheel bolts, use the air pump to inflate the "spare", etc.) are truly amazing!

You are right Karl. I popped the plastic plug on the front bumper and installed the tow eye. I was actually able to drive the car onto the flat bed myself. I put it in park and gave him the key without locking it up. I left forgetting to flip the switch on motion detector for towing. They do all the towing for MB, Jag and BMW in the area so I hope they figured it out. Calling the dealer this morning to find out the scoop. I will keep everyone posted.
