TECHNICIAL INFO

Does anyone know of a gm web site that post technicial news or known problems on vehicles that only technicians and serivces reps would know...we have a problem that gm will not admit is a "known" problem and want to know if there are any others out there...obviously gm TAC can't tell us much and we are facing buy-outs if not corrected.there are no bulletins addressing the current problems with the duramax diesels in the 2001 gmc trucks...and TAc will not admit there is a problem.
