Sorry for the dubb post. They told me the final drive was out. I got a chevy cobalt ls as my rental. It has the the 2.2 eco-crap. My GP has power everything the cobalt has power nothing not even cruise control. I have a 45 min one way trip to work no cruise sux lol. On a side note I was wondering what the normal operating for the 4t65e. My GP trany was always hitting 200+ wondering if maby that was destroying the trany so much
