can i just say i did this and it was the worst mistake of my life....
Amsoil + Subaru tranny = shitty shitty shifting, slow syncros it was terrible..
my fix until i get a tranny flush done
suck out 2 quarts (which was metallically from all the bad dog-teeth grinds)
1 quart of royal purple
1 quart of Pennzoil syncromesh
