Oh, and thanks for the info Notamember. I'm sure the service advisor will/would look at me cross eyed if I suggest this as the problem... Looks like until GM issues a service bulletin we are all S.O.L.! -John

So someone who assembles the transmissions at the factory doesn't know how to properly build the transmissions because mine has done it from new/1 mile... -John

Bump! Thanks, -John

Hello, Has anyone else noticed that when your truck is cold/1st start of the day that rpm's flare when the transmission shifts from 2nd to 3rd gear? This happens on my 2011 2500HD(since new, currently only 9000 miles on it) and also a co-worker who has a 2012 Silverado 1500 also has the same complaint. He brought his to the dealer and they were indeed able to verify the issue but said that they had never seen this issue before. The service dept. called Tech Line and they said that they know of the issue but have no fix for it at this point and time...?? Is anyone else experiencing this or have had a solid diagnosis/answer/fix from theIr dealer? Thanks, -John
