Factory Service Manuals

[Fumes]

Just got my Helm's Factory Service Manual set for my 2006 GMC, but quickly going through thme doesn't have information specifically for the LBZ (D) motor, only the LLY (2). Am I missing something? Is this going to be a problem? :confused:

If they haven't integrated it into the manual, it should have included a supplemental to include the LBZ. Although, there is really no significant difference between the two for the 2006 M/Y (programming and very minor cosmetics, essentially). Look through it closely before giving Helm a call.
