Good question Doug
I believe you are referring to Service Manual D2070.
If so, then you may be looking at the transmittal letter section of the manual. We do incorporate the TR into the body of the manual. In addition the transmittal letter/instruction page is usually placed in the front matter.
But in looking at this manual, it looks to be done in the older process (where we put the TR page in front of the page that it revises instead of replacing the revised pages). I will have this pub redone to replace the old pages instead of having both.
