Gm Service Bulletins

I Have 95 Aurora With 112,000 On It. Up Until Now The Car Has Been Great ! But Its Starting To Eat Me Alive. Fix One Thing And Something Else Goes Bad. I Was Wondering Does Anyone Have Access To The Gm Service Bulletins For This Car, Or Is There A Website I Could Get On To Check Them Out. There's A Fix Out There For A Bad Trans Wire Harness That Acts Like A Wick And Sucks The Tranny Fluid Out, Anyone Got Any Ideas Or Sources For The Bulletins ?

once the page for your car comes up click on maintenence in the left column
next click on Technical Service Bulletins

the ACNA may have more help too in the way of practical experience
