I AM THE OWNER OF A 1994 MAZDA MX-6 (4 CYLINDER, AUTOMATIC TRANSMISSION). BECAUSE OF WHAT I BELIEVE MAY BE A MANUFACTURER DEFECT OR DESIGN FLAW, I'VE BEEN FORCED TO REPLACE THE TRANSMISSION IN THIS VEHICLE TWICE OVER THE COURSE OF ABOUT THREE YEARS. BASICALLY, AN ELECTRONIC OVERDRIVE SWITCH WILL RANDOMLY BEGIN IT'S FUNCTION WITHOUT HAVING ANY CONTROL OVER IT. A LIGHT ON THE DASHBOARD WILL FLASH "HOLD" CONSTANTLY UNTIL THE PROBLEM IS SOLVED OR THE COMPUTER IS RESET. WHEN THIS HAPPENS, WHICH QUITE FRANKLY HAS BEEN VERY FREQUENT, THE TRANSMISSION JERKS AND STRUGGLES TO OPERATE PROPERLY. THIS ALSO RESULTS IN SOMEWHAT OF A LOSS OF CONTROL OF THE VEHICLE AS MAINTAINING HIGHWAY SPEEDS AND TAKING SMALL TURNS CAN FEEL VERY UNSAFE BECAUSE THE CAR GIVES THE IMPRESSION THAT IT'S NOT HOLDING THE ROAD VERY WELL. NOT TO MENTION THE FACT THAT I'VE HAD TO SPEND A TOTAL OF ROUGHLY $5000.00 FOR TWO TRANSMISSION REPLACEMENTS. I'VE DONE SOME RESEARCH AND I HAVE FOUND THAT I AM OBVIOUSLY NOT THE ONLY ONE WHO HAS EXPERIENCED THIS VERY SAME PROBLEM. I STRONGLY BELIEVE THAT THIS CAR CANNOT BE OPERATED SAFELY OVER A CERTAIN AMOUNT OF MILEAGE. MY FIRST EXPERIENCE OCCURED AT ROUGHLY 70,000 MILES, THE SECOND AT ABOUT 95,000. *AK
