| Both the dealer and chevrolet customer service stated the truck was to old and to many miles. the dealer also stated the repair price was already discounted. it's bad when a truck thats 5 1/2 years old and 48,000 miles is beyond help and they advertise solid as rock and their trucks last longer. | |||

| While going down a dirt driveway, realized the vehicle was in 4 wheel drive low, put the clutch in expecting the vehicle to coast/free wheel to the bottom of the driveway at which time i would have put into 2 wheel high. at which point, while it was freewheeling, the plastic loop that connected the clutch actuator rod to the clutch pedal snapped. suddenly engaging the clutch that was spinning to the engine(diesel) that was at an idle. the engine compression prevented the motor from increasing rpm quickly. result was a relatively new clutch disc was torn apart. this was the third clutch in this vehicle. the original disintigrated at 96,000 miles while entering a state highway from a fast food restaurant. clutch material was not excessively worn. replaced with a gm clutch assembly. pilot bearing had failed. needed new imput shaft to transmission. second clutch failed after 24,000 miles. clutch disc disintigrated and jammed clutch assembly. rocked the engine severly causing damage to exhaust. road wet going downhill. no weight in bed of truck. tail began to slide sideways. replaced with napa/borg warner assembly. unit had 20,000 miles on it when pedal assembly broke. our concern is that other vehicle of the same manufacturer with standard transmission have the same potential part failure when driver not expecting it. in our case the vehicle traveled 100+ yards on a dirt road before entering a public way and another 100 yards up a public way before coming under control. had there been vehicles traveling either direction the results could have been worst. should this failure occur when vehicle was stopped at a crosswalk, the driver would not have time to react. there are numerous other potential situations that come to mind that could result in fatalities. we were lucky . our family of 5 and our neighbors, who fortunately came by after, survived without injury other than the untimely death of our clutch which had much useful life left. photos available. *ak | |||
