Need a few suggestions....Plugs? Oil? Trans Fluid?

Champion used to be good plugs. Not now. Offshore manufacturing. I have had a couple failures recently. So unless they are free or very old stock i wont screw em in.

im my opinion, atf is far superior to hydraulic fluid. It was my understanding type f was developed for the clutch lining ford used in the 60’s and 70’s maybe 80’s
And i dont understand why it would make such a difference with current clutch materials.
Type f is still available, so it still has some purpose.
