au contraire, it is a "crush" washer, unless Subaru makes contradictory statements. On another note; Subaru has a new gear oil which is synthetic, for their trannys. Unfortunately I cannot remember the name of it, but it supposed to be the shizzle. It only comes in 5 gallon bucket (from what I know) if someone is willing to go in on it split the cost and divvy I would not object. I will try to find the post on Nasioc. Neo is good stuff aswell. Both claim to bring back downshifting into first gear at 20. I have to be nearly stopped for mine to engage.
