Just wondering if anybody has had TSB 06-08-64-035E performed on their trucks? After doing some research, it seems the problem I'm having is outlined in the TSB. But in that research I haven't seen any talk about this since '08 or '09. Not sure if this TSB would even apply to my truck or not. So I guess I'm wondering if anybody hat this TSB performed recently or even if GM Customer Service can chime in to see if this is valid for my truck. Thanks!
