VEHICLE WOULD BE STOCK ON 1ST OR 3RD GEAR WITHOUT ANY ERROR CODE ENGINE LIGHT OR TRANSMISSION LIGHT ON. THAT CAN HAPPEN ANYTIME. ON TAKE OFF AT RED LIGHT OR CRUISING ON 5TH 6TH OR 7TH SHIFT. THIS IS AN AUTOMATIC TRANSMISSION WITH NO MECHANICAL ISSUES. I AM GUESSING IT IS A SOFTWARE ISSUE. VERY DANGEROUS IN TRAFFIC OR HIGH SPEED HIGHWAY BECAUSE THE VEHICLE STALLS UNINTENTIONALLY. A RESTART OF VEHICLE FIXES THE ISSUE.

I SLOWED DOWN TO MAKE A TURN AND THE CAR WOULD NOT ACCELERATE. IT APPEARED TO BE STUCK IN HIGH GEAR AND DID NOT SHIFT BACK DOWN TO A LOW GEAR. THIS HAPPENED TWICE OVER A 3 WEEK PERIOD. BOTH TIMES I ALMOST CAUSED A TRAFFIC ACCIDENT BY BEING STUCK IN THE MIDDLE OF THE ROAD. I TOOK THE CAR TO THE MB DEALER AND WAS TOLD IT WAS THE CONDUCTOR PLATE SENSOR BOARD THAT CONTROLS THE TRANSMISSION. THE FIX WAS $1300 TO REPLACE THE UNIT.

MY CLK 350 CABRIOLET STATED DRIVING DIFFERENT. AT FIRST, WHENEVER I WOULD SLOW DOWN AT A STOP LIGHT, THE CAR WOULD CUT OFF. EVERYTHING WOULD ILLUMINATE ON THE DASH AND I WOULD HAVE TO TURN IT OFF AND BACK ON TO DRIVE IT AGAIN. THE BIGGEST ISSUE IS THAT WHEN I WOULD DRIVE, THE CAR WOULD NOT SHIFT OUR OF GEARS PROPERLY, AND IT WOULD VERY PAINFULLY AND SLOWLY ACCELERATE ITS SPEED. IT WOULD JERK, LIKE THE TRANSMISSION WAS NOT FUNCTIONING CORRECTLY. COME TO FIND OUT, AT 62,000 MILES, MY CAR NEEDED A NEW TRANSMISSION, WITH NO LOGICAL EXPLANATION GIVEN FROM ANY BENZ DEALER. SPEED SENSORS, CAMSHAFT, CONVERTER ALL MALFUNCTIONED. *TR
