LLY Rough idle update

[Cliffee]

Does anyone know what the latest LLY rough idle update # is? I'm picking up an 05 this week and I want to get it updated before I pick it up. The invoice shows August so I'm sure it doesn't have the latest. My sales buddy says he will get it done if I can get him the GM # update. Of course service supposedly knows nothing about it!

Thanks

All they have to do is hook it up and read the VIN, then check for available updates.

I just got out of the chevy dealership this afternoon. Here are the codes I got for my update. It took them a while since the hand held Tech 2 wouldn't recognize my truck VIN. After 4 phone calls to GM they got it. We will see how it runs it sure sounds better.

Next day it runs great and no more clatter.
