If you're referring to the Fluid FAQ post, then I'm glad you enjoyed it. You'll find similar treatments for other topics if you follow the Frequently Asked Questions link, which also appears along the left side of every page of this site. Though it's a specialized sub-forum, PackardInfo is much more than a message board; take time to explore its treasures.

I'm not personally aware of any simple way to tell what type fluid is in there. I know that some of the petro suppliers used to offer analysis service, but I haven't dealt with that in years. However, I doubt that Dexron and Type F are so different/incompatible that you had to completely flush all traces of previous fluid. Else, there would have been warning to that effect on the TrickShift bottle. Also, it's not like we're dealing with finicky modern transmissions, here, which only work with synthetics and only a specific blend - that any deviation would cause trouble.

Sounds like the screen was plugged so bad that the the trans couldn't pull enough fluid to develop sufficient pressure to apply the bands or clutches. If else nothing but the converter and front pump was turning, that should limit the chance of any friction-related damage.

Still, I don't believe the lint that you found occurs naturally in any transmission. I agree with HH56's suggestion that something was left inside the trans that didn't belong there.
