Hi,
My name is Brian and I am new to this fourm. I have allot of questions on my truck.
I just bout a 04 2500HD duramax, My first question I have do all of the diesels have the alison trans in them. And also what is the differnce between a LLY and a LB7 I looked at the stiker on the door and it has 10-03 on it. And do you guys know the codes for the rear I think I have a 373 posi but not sure. And do all of the trucks have the plug so I can plug it in, It is starting to get cold hear in PA. Thanks for any help you can give me.
