THE AUTOMATIC TRANSMISSION HAS DEVELOPED A CONDITION THAT CAUSES THE TRANSMISSION TO SHIFT VERY ROUGHLY AT LOW SPEEDS. THIS SHIFTING CAUSES THE VEHICLE TO JERK AND STUTTER WHEN DOWN SHIFTING OR SHIFTING FROM 1ST OR 2ND GEAR. I HAVE HAD A TRANSMISSION SERVICE, REPLACEMENT TRANSMISSION, REPLACEMENT RADIATOR ALL INSTALLED TO NO AVAIL. THE CONDITION IS AT BEST A NUISANCE, AND AT ITS WORST A SAFETY CONCERN. THIS ROUGH SHIFTING OCCURS IN THE LOWER GEARS, AND AT LOWER SPEEDS.

WE WOULD LIKE TO SUBMIT A COMPLAINT. WE OWN A 2004 CLK320 WHICH HAS PRESENTED WITH CONTINUING PROBLEMS. WHEN WE PURCHASED THE VEHICLE, THE REAR AXLE ALIGNMENT WAS DEFECTIVE IN WHICH REQUIRED REALIGNMENT AND REAR TIRE REPLACEMENT. AT 21,937 MILES THE CAR PRESENTED WITH TRANSMISSION SHIFTING PROBLEMS. THE CAR WOULD JERK/STALL WHILE BEING DRIVEN. IT WAS VERY DANGEROUS AS IT WAS DIFFICULT TO MERGE WITH TRAFFIC, BUT MOST IMPORTANTLY, WE FELT WE WERE GOING TO GET REAR-ENDED AND CAUSE AN ACCIDENT. THE MERCEDES-BENZ DEALER SERVICE DEPARTMENT DIAGNOSED THE PROBLEM WHICH REQUIRED THE TRANSMISSION TO BE FLUSHED. THEN AGAIN AT 28,714 MILES THE VEHICLE PRESENTED WITH RECURRING TRANSMISSION SHIFTING PROBLEMS, JERKING & STALLING.. WE SCHEDULED A MERCEDES-BENZ DEPARTMENT SERVICE AND THE DIAGNOSES WAS TO REPLACE THE ENTIRE TRANSMISSION REPLACE AT OVER $9,000. WE REQUESTED THAT MERCEDES-BENZ OF AMERICA REPLACE OR ASSIST US WITH THE REPAIR OF THE VEHICLE AT NO COST TO US THE CUSTOMER SINCE THE VEHICLE IS A "LEMON". THE MERCEDES BENZ REPRESENTATIVE SAID THAT HE WOULD CONTACT THE DEALER AND GET BACK TO US WITHIN 24 HOURS. WE NEVER HEARD BACK FROM HIM EVEN AFTER LEAVING NUMEROUS VOICE MAIL MESSAGES. WE HAVE SEARCHED ONLINE AND FOUND NUMEROUS SIMILAR TRANSMISSION COMPLAINTS. THIS PROBLEM IS EXTREMELY DANGEROUS AND IS A SAFETY ISSUE AND MERCEDES-BENZ SHOULD RECALL THIS VEHICLE. *TR
