There's a ton of controversy around CVT's (Continuously Variable Trasnmission) and their fluids and the Suby's CVT is no different. Some say they have "Lifetime" fluids, are sealed units and don't require any maintenance. Others say they must be maintained. Is there a mandated change interval? WHAT fluid to use? Dealers are either saying "Dont touch it" or are charging STEALERSHIP prices to do it. Can a regular guy DIY it for cheap? Maybe.
