Is Penrite Pro Gear 75W-85 GL4Plus Ok for the FS5R50B?

[NADSyourUncle]

As the title suggests, I am looking to confirm whether the Penrite Pro Gear 75W-85 GL4 Plus is suitable for my Patrol's FS5R50B transmission?

I bought this stuff a few weeks ago and its finally time to put it in, and I was browsing SCA for other stuff and double checked its specs, noticed its **GL4 Plus**.
I know not to use GL5, and I know it says compatible where GL4 is recommended, but hoping to hear from the masses.

This transmission was freshly rebuilt, so I want the best oil for it.

And if anyone knows, is it also ok for the tranfer case? Looking to avoid ATF based on (1) I'm going outback and value reliability over fuel economy; and (2), my transmission specialist said to go for gear oil over ATF. Otherwise I'll stick with the Nulon 75W-80 i already have.
