Ford Service Manual -T or J Shift Info Inside?

[El Kabong]

I bought a set of 73 shop manuals for my 73, which came with a "J" shift transfercase. The 73 manual shows a "T" shift. I picked up a 74 manual, figuring it was a mid-year change, & the next year would have the revision. It also showed the "T" shift. Oops. I am finding lots of info from other sources, so I guess I don't really need it, but it seemed odd that the factory service manual would omit a change like that.

Do all the manuals show only a "T" shift? Is there a service bulletin that shows the differences? Or did I miss the other half of the transfer case section?

Here are the different J diagrams.
