Subaru Enthusiasts Car Club of the Sierras - View Single Post - 6mt fluid choice? Notchy especially in 3rd.

I am pretty sure the 6MT shares fluid between the diff and gearbox, but if not there will be 2 dipsticks on it. The diff does require GL5 according to the service manual, but thousands of Shockproof users who aren't reporting front ring and pinion failures can't be missing that. Personally I'm comfortable using Redline GL4 products in my gearboxes.
