There's nothing really special to a compensator its only demand is  abundance of lubrication. What does EP do for it?

It's an Extreme pressure additive, like that in gear oil. From what I have read, the sliding cam that rides on the sprocket is the issue and it's needs an EP rated lube.

Curious,  what do you use in your primary with the rated EP  Or do you add it ?

I ended up getting Spectro Heavy Duty Primary Chaincase 85 weight oil. Baker also recommended that too. Waiting on plates and Heavy Duty Diaphragm Clutch Spring. I misplaced mine. Can't find it anywhere! I also have the Baker Heavy Duty Throwout Bearing Kit. I had it but never used it. The Baker 6 speed O.D. gearset works great! Baker told me thier 6 speed Direct Drive wouldn't hold up to my motor.

Don't you hate it when that happens (losing chit)?  This afternoon I was farting with my old Road Glide for another hour or so.  Couldn't find the o-rings that go under the rocker arm assembly.  Knew they were out there somewhere.  Just knew it.  Couldn't find the damn things anywhere.  Wasted a half hour looking for them.  Then wasted another 45 minutes back and forth to the dealership to get a pair.  When I got home I found the originals.  Humbug!

You obviously have an infestation of garage gnomes. They are evil creatures with a wicked since of humour.  They will move parts and tools so you can't find them. Once you give up looking, they will put them back so that when you come back they are there. Haven't found an exterminator that knows how to get rid of them yet.   ;D

They suck.  Total bastards they are.  Demonic.  Back in 2008 I lost a set of adjustable pushrods in the middle of working on the red SEEG I used to have.  Gone.  Vanished.  Nowhere in the shop or (where they should have been) on the parts cart I was working from.  Spent hours looking for them.

Finally to finish the job ordered another set.  Of course, because that's what you do when the garage gnomes and the Travel Gods conspire to screw with you.

A year later I found the pushrods.  Under a stack of rags I'd covered the pushrods with to protect them.  In a drawer.  Found them while working on the engine on my Road Glide.  So used them there instead of ordering a set for it.  Had no reason to touch them since until (for real) this week when working on the Road Glide again.  Took the pushrods out and reinstalled (last night actually) and called them bad names both times; just for messing with me a dozen years ago.

As the saying goes, it was in the last place you looked.  Which is pretty obvious; who finds something and continues looking for it.

Back to primary oils, I've tried just about everything and settled on the MA2 spec motor oils.  Cleanest drain plug magnets and best clutch grab.

Do you know what temp the ATF fluid is rated for?

I have seen primary cases, measured by an infrared thermometer reach temps over 400 degrees in extreme cases.  Even in typical highway usage it is going to be over 275 degrees.  I know that the atf in my truck never gets above 180.

Just something to think about...

ATF is just like motor and other oils, it starts breaking down between 250 and 275 degrees.
