"Where can I find Ford technical service bulletins (TSB's)?
How to Find Free TSB's. To find a TSB, go to NTHSA's Safety Issues & Recalls page. Type in either your vehicle's unique 17-character vehicle identification number or its year, make, and model. Feb 4, 2020"
In many cases, NTHSA will give you the TSB number/title, BUT, not the TSB content itself. With the TSB number, any Ford dealer can look up the TSB for content, but unless they know you (read: like you) they won't do it for free or at all. Alldata is the same way. Do you know anyone (repair shop) with an Alldata subscription?
