When buying my truck, the Helms service manuals were part of the deal. I was not supposed to get them until July. They came in today but I see no reference to the LBZ and I can't find a list of what is covered. I see references to the LLY in the index but no LBZ. Does anyone know if they are available? If I have the right set? I have the GMT/06-CK8PU. It says the information cutoff is 1/30/06 in the front of the manual.

does your new manual have the van engine, and electrical schematics?

The soonest I've ever seen a manual come out is 9 months after production starts on the product and if the LLY manuals just came out that would be just about right. So you might have to wait until Sept. for the LBZ.

The 06 LLY and LBZ are basically the same internally anyway. The difference is in programming.
