Yes, and just re-checked the manual, it says ATF

I have no way to see in there or measure the clearance in the
clutch with the pedal depressed. I think it's to tight (of a space) to get anything in there to check it. Before I take it back apart, I will try to reach up in there and check it...

I put more wave in the disc by carefully bending it, it bends easily.

The clutch repair shop told me that the discs have the wave to help them spring away from the flywheel. And they said over time, the disc will go flat from setting with the pressure plate squeezing them.....their words not mine.
And seeing how more wave did not help, (it may have hurt) it is possible the clutch people are not so well informed?
It had a bit of wave.....and it dragged a bit too.....now with more wave it drags MORE....

It is a ball bearing pilot bearing and it is very free.

I can install the shaft in the clutch and lay it in the trans housing and it will slip back and forth a bit....that is how 'free' the shaft is...

I think the disc needs to come back out and be flattened....perfectly flat. No wave.....no wobble
