Looking for a stock file for a 2005 GMC Yukon os 12587603. I tried looking in the Dropbox link but that does not work anymore. Truck is a 5.3 awd

Anyone know where I could find a file?

The files I found with that OS are all 2004 vehicles. Do you need a specific engine/transmission combination?

As Al said, I've never seen a 2005 or newer file using the '7603 OS. Probably because(from memory) 2005 and up LS1B's had a different pedal and TAC module.

Anyway, maybe this will help.

I apologize it is in fact a 2004. I don't have my V2 with me this evening but I'll grab it tomorrow to verify OS
