NHTSA Complaint #723403 — 1998 CHEVROLET CORVETTE

I FIND THAT THE GEARS GRIND BETWEEN SHIFTS AT EITHER HIGH SPEED OR HIGH RPM'S. AT THE BEGINNING ONLY 5 GEAR HAD GRINDED NOW I FIND THAT GEAR 4 AND 6 GRIND. THE GRINDING OCCURS OCCURS AS THE RPM'S APPROACH 4,500 AND HIGHER. ALSO THE GEARS ALSO GRIND WHEN SPEEDS EXCEED 140KM/H OR 88 MILES/H. I HAVE ALREADY HAD 3 PRIOR MECHANICAL PROBLEMS WITH MY 6 SPEED TRANSMISSION. THE FIRST WAS A TRANSMISSION LINK FAILURE. THE SECOND WAS A TRANSMISSION LEAK. THE THIRD WAS A BROKEN SHIFTER. THE VEHICLE WAS TOWED TWICE DUE TO THE INCIDENTS. I FOUND COUNTLESS OTHERS WITH THE SAME PROBLEM AT WWW.C5-CORVETTE.COM IT SEEMS TO BE A SYNCRO PROBLEM. NO DEALER HAS BEEN ABLE TO RESOLVE MY PROBLEM TO DATE. I HAVE BEEN TO 3 DIFFERENT DEALERS FOR A TOTAL OF 5 TRIPS, NO CORRECTION HAS BEEN MADE THUS FAR. *AK
