2005 TOYOTA COROLLA MATRIX Power Train Problems

ONLY 94,000 MILES, FULLY DEALER MAINTAINED, 5 SPEED MANUAL TRANSMISSION. TRAVELING AT EXPRESSWAY SPEEDS AND LOUD SCREECHING/BANGING FROM TRANSMISSION. WAS ABLE TO DRIVE 6 MORE MILES TO DEALERSHIP, BUT MOVED TO RIGHT LANE AND WENT SLOWER. STILL WAS ABLE TO SHIFT, LOWER GEARS WEREN'T ENGAGING PROPERLY AND CAR STARTED DYING ON THE ROAD. DEALER DIAGNOSIS FOR $100 IS THAT IT NEEDS AN ENTIRE NEW 5 SPD TRANS AND CLUTCH ASSEMBLY, ALTHOUGH CLUTCH SEEMS FINE.I'VE DRIVEN MANUAL TRANS FOR OVER 40 YRS. THIS CAR NEVER EVEN HAD A CLUTCH REPAIR. RESEARCH ON THE WEB INDICATES THAT THIS IS A KNOWN POINT OF FAILURE THAT TOYOTA HAS CHOSEN NOT TO FIX AND THE POTENTIAL DANGER OF HAVING THIS TRANSMISSION BLOWING OUT AT HIGH SPEED COULD HAVE CAUSED A MAJOR CRASH ON THE HIGHWAY HAD I NOT BEEN SKILLED AT GETTING THE CAR INTO A SAFE AREA. *TR

REPORTING SUSPICIOUS CAR BEHAVIOR, IN RESPONSE TO RECENT CONCERN FOR CAR HACKING AND CYBER ATTACKS ON CARS.
