Which direction are the steel plates? Did you install the steels in any direction?

I have found that the adjustment the manual states, doesn't work. Run the adjustment rod in till it touches, then back it off 1/8 turn

You got the hardened pressure plate or the original aluminum one? The original aluminum one can wear and had an extra ring that goes on it before the plate to increase the height.

If it's the original, easy to tell just based on color. Its either aluminum or the baker upgraded one is more brownish due to the hardening.

If it's the aluminum one take a look at where it sits on the plates and if you can see grooves or feel them with your fingers it's gone.

Not much tolerance wiggle room on these clutches due to the design.

The slipping seems to happen when the Primarily actually finally gets hot

No effect if more oil is used. It's called memory is the steel theory. Place hands together with palm to palm. See how the fingers fight each other if you push one against the other? Place hand on top of the other. See how both fingers all move in the one direction?

So theory wise, they stamp out a plate, were one side is round, the other side of that outer edged is sharp from the sheer. All the cut sides face the pressure plate. Friction plates might have a flat and round side at the edges, then same direction. If say there is a marking on the one side of the plate, can't tell at all from the edges, then the marked side faces the pressure plate.

Pressure plate has two designs. One is a wave plate made of steel spring and is curved when static, but is flat as a pancake when all the plates are new and the stack height pushes the wave plate flat. Whereas, the other style pressure plate is aluminum and does not flex. So far, plate position, and stack is showing a flat wave plate, yes or no, are you wave plate or aluminum plate, and is the wave plate flat if applies?

Next is pushrod distance and screw adjust, then cable slack finalizes the whole rebuild. So if cable has a locking outer cable system, hide the threads and make the outer cable as short as possible. Pull clutch lever in so this sends the pushrod [somewhat] home. At the pressure plate adjust nut, run the screw in so that too pushes the rod home. Pull clutch lever again and release. Go back to the screw and see if it will travel in more? This is just a lightly seated screw on the rod, then back it out 1/8th out and tighten the lock nut. Go to the outer cable and run it out so it takes out all of the slack at the lever and perch. Pull the lever in and take out even more if say something hung up and slipped back in say. Where you have almost zero lever freeplay, you took out the 1/16 inch gap is down to 1/8th or less at the perch to lever. When it gets hot, feel the gap at the lever. It should show excess freeplay if any... Normal.

A good way to tell if the pack breaks free is to pull the lever in, spin the pressure plate by hand. It should be effortless. The wave plate might need another steel to flatten the wave more.

Nothing wrong with using ATF in the primary. I use ATF type F in all my standard material clutch installs. I use ATF Dex/Merc synthetic in all my Carbonite plate installs.
