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 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.
