I have an 03 Silverado SS with a transgo shift kit, vette servo, also a radix with a 2.85 pulley. The truck doesn't pick up like it normally does after I punched the gas once and heard a lound squeal. What can be the problem. It shifts extremely hard now and a little while ago, my truck jolted back then forward, made that squeal again, and it shut off on me, all while I was in drive. I was going about 5 mph.
