if you don't have a manual, contact the dealer and they can supply you a new one ( or you can probably find one on ebay ). also a lot of users recommend getting the workshop manual. from what i understand it has an answer to every question in the world...

partsgeek sells the fluid for $19. not sure of the price anywhere else. ( not an endorsement or anything for partsgeek, but i do use them from time to time for parts ).
