I was hoping someone would be able to help me out...
I have a 2005 GTO 6.0 and recently I have been noticing a grinding noise when starting out in 1st gear (as the clutch is released) and my monitor says 'low traction'. I hear the noise in the rear of the passenger side. It doesn't do it every single time coming out of 1st, but at least 2-3 times a day. I had a mechanic at Firestone take it for a test drive while getting some new tires and of course it didn't do it for him...Any ideas of what this could be?
