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.

I've been looking all over stores around my area and couldn't find some of these oils. So it really helped finding all of them in one spot. My transmission shifts like butter now and I couldn't be any happier! The fourth gear grind is even gone under boost which I was skeptical about till now.

I recently used the cocktail and it has completely changed the way my transmission shifts. I was getting a scratch in 5th when getting on the highway. That is completely gone. You can barely feel it shift gears. Also the reverse to first transition is much smoother. I remind this even if it's not time to change the fluid.

Trans shifts much easier even in frigid temps.
