Fly Wheel

99 Suburban, Bought Last Year With 68,000 Miles. Flywheel Went Out At 72,000 And Again At 86,000 And Again At 92,000 And Again At 102,000. Transmission rebuilt at 100,000. Pulled Original History On Vehicle, Shows Fly wheel Went Out Under Manfacturer's Warranty At 26,000, then Again At 32,000, And Yet Again At 62,000. Hmmm, Problem? Have Loan On Vehicle, Two Service Garages Refuse To Fix/warrant the labor But We're Stuck With A Loan And A Suburban That Breaks Down Consistantly----any Suggestions On Cause Of The Flywheel Going Out??? and maybe a permanent fix (oh yeah, GM says not our problem)
