I purchased a complete 7 volume set of the GM service manuals when I had my '03 GMC D/A. I got rid of the '03 (long story) and I just recently got an '04 GMC D/A (LB7). There doesn't seem to be any noticeable changes between the '03 and '04. Will the '03 manuals cover the '04? I've heard that the Allison had some hardware updates for '04. Is that true?


Thanks!

I think I seen somewere that the Allison updates were only going to be on the LLY Duramax.
