I have a 2001 Chevy 2500HD 6.6 V8,and I was driving on the interstate the other day with my cruise set at 75,then it just all of a sudden lost power.It didn't try to go dead or anything it just got real weak even if you hold it to the floor it barely builds up speed,I've asked around and everyone pretty much thinks its a Cadillac converter but I wanted to get some other peoples opinions?
