    I plan on changing my gearbox oil on my 1999 F355 Spyder manual 6. I just bought some Redline 75w-90 High Perpormance Gear Oil. GL-5+. It says it's for "limited slip differentials". The part # is:57904. After reading some posts and doing some research I see there is another Redline product that is NS. Or non-slip with the GL-5 rating. Did I buy the wrong stuff??? I really need to know which is best. Before I put the life juice in her. The original stuff is still in there. Shifts perfect and I want to keep it that way! I would very much appreciate info on this. Thanks in advance.
    Mike.

    It does seem like every one runs "NS" in their 355's transmissions. I've got several bottles lined up in my garage, waiting to go into mine. I put the same stuff my Boxster 20k miles and several years ago and never noticed a difference from whatever Porsche had put in there.
