04 CLK500 tranny/torque converter problem

i just bought a 2004 clk500 and after my first drive after purchasing it i notice a weird noise...i take it to mercedes and they tell me i have to get my tranny fixed and the torque converter is busted....the car has 38,000kms...is this normal???should i ask for money back from my purchase or even take em to court....im sure they knew of this problem prior to my purchase....its covered by warranty, but should i sell it or do u think this problem will just be the first of many more???
thanks ahead of time

Your car is under warranty. Don't touch it, and take it to a Mercedes Benz dealer only. Don't let anyone else other than a MB dealer get close to it.(they may somehow give Mb a reason to void the warranty)
On another note, this is not normal for your car. I suspect they mis diagnosed it. I would venture a guess of a bad speed sensor in the valve body electronic plate. Is it in "limp home" mode?(you have only 2nd gear and reverse in this mode). In any event, your car has a bumper to bumper warranty for 50,000 miles or 4 years from the original purchase date, so don't worry to much, the clk cars are very nice machines.

mb engines are great, but there transmissions suck

it most likley is not the torque converter it is the trans control module. I have not heard of any problems with the torque converters.
