Open the full vehicle complaint log (all categories)OWNED A BRAND NEW 2007 MERCEDES SLK 280 AND THE TRANSMISSION WAS PUSHING AND PULLING TO THE POINT THAT IT WENT OUT AND HAD TO BE COMPLETELY REPLACED; AND ULTIMATELY, IT WAS A 'BUY-BACK.' AFTERWARDS, I HAD ANOTHER NEW MERCEDES 280, NOW A 2008, AND THE TRANSMISSION WENT OUT ON THAT ONE TOO. BIG MISTAKE ON MY PART; WHAT ARE THE ODDS THAT ANOTHER NEW ONE WOULD GO BAD? THE MERCEDES 7 SPEED AUTOMATIC TRANSMISSIONS WAS A COMPLETE NIGHTMARE EXPERIENCE FOR ME. SINCE 2008, EVERY TIME I SEE A MERCEDES SLK, I SOMETIMES ATTEMPT TO TAKE A MOMENT AND ASK THE DRIVER OF THE CAR: "HEY, HOW'S THE TRANSMISSION?" *KB
