| 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 | |||

| While driving the consumer noticed that the service vehicle soon light had come on. after taking the vehicle in for a diagnosis, the consumer was told that an electronic brake traction control module was needed. the consumer feels that this is a defect becuase the vehicle has low mileage, and knows of others with similar problems. the manufacturer is aware and was willing to split the bill 50/50, but the consumer feels if they don't cover all charges then further action will be taken. (the cost of total repair is $1256.36) *scc | |||

| Dash display said traction control system inoperative and then 'reduced power mode'. power dropped to zero, although engine continued to run. we were in the center lane of a crowded freeway and just managed to get to the shoulder. it was extremely dangerous. it happened several more times on the way home. the traction control system was not active (summer, dry, straight road). disabling the traction control system had no effect. it makes no sense to endanger those on the road by dropping the power to zero for a trivial reason.*ak | |||

| The passenger side seat belt jammed for at least the fifth time after the dealer installed the clip required by the recall. an accident occurred a few minutes after the last jam. my passenger was very lucky not to have been injured with more than a bruise on her leg and a bump on her head. when shifting from first gear into second at about 35 mph (engine speed at about 3300 rpm), the rear end came around to the left causing the car to do a 180. the traction control system never intervened as it has done many times in much less severe situations. the car then went sideways across traffic into a curb and then over the curb into a fence on the edge of an overpass. a police officer was a few cars behind me and saw the entire incident. in his police report he estimated my speed at 35 mph. *ak | |||
