This is some commercial/fleet fluid,universal ATF in nature, I have some 20 wt, comes in 6 gal pails, use in my ps also. Trans fluid is basically a hyd. oil with different addatives like type 4 says, think wet brake compatibility being the key here, I use Mobilefluid 424 also, Cant recall the cost, but better then buying qts at autoparts store.
