FINALLY!!!....a place to get all the ingredients for the Transmission Cocktail! This cocktail is the famous tranmission oil mix that many many subaru owners have used to fix that bad shifting/grinding manual transmission.

No more searching around town trying to find all the ingredients and not being able to find them all...GrimmSpeed™ has them all in stock and ready to ship out to you.

If you'd like a smoother shifting gearbox, this is for you.

NOTE: This mix is only ideal for all 5 Speed Subaru Transmissions.

ALL OIL IS NON RETURNABLE

When filling up your transmission you will use ALL of Penzoil, Lightweight Shockproof, and 1 full bottle of the Castrol Hypoy C, then you use approx. 1/3 to 1/2 of the remaining Hypoy C until the transmission is full.
