Product Description

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.

  1. great product!

    Posted by Tyler Minnig

    Love the simplicity of the cocktail. Works amazing in my built 5 speed


  2. Waste of money

    Posted by Jacob

    I purchased this cocktail to see how it would fair. I needed to drain the transmission anyhow to replace a seal and cv-axles. after a month or so of daily driving accompanied by some spirited driving my synchronizers aren't happy with this mix. after paying almost $80 between the cocktail & shipping I am very disappointed in this product. It may work better for unmodified vehicles but I definitely don't recommend it.


  3. Not snake oil!!!

    Posted by Aaron L

    Use to grind always in reverse and when going into 5th after a hard pull. A bit of cocktail and not a peep for months!


  4. Worked for me!

    Posted by Doogie Fresh

    Night and day difference? Wouldn't go that far.
    Is my 1st gear grind gone? Absolutely!
    Scotty's cocktail juice has only been in my tranny for 500 miles and she's pretty happy so far..... I would recommend.

  5. Pour me another bartender

    This cocktail truly works like a champ! Had the usual grind from 3rd to 4th and it hasn't done it since this was added.


  6. Awesome mixture.

    Posted by Ray

    This mixture is amazing. My 2012 WRX shifts smoother and the transmission is quieter since I switched to the mix.


  7. good product

    Shifting is so much smoother, I was kinda hesitaten at first to try the cocktail until I did some research and found out everyone loves it.


  8. Better than Extra S in my trans!

    Posted by John H.

    A few months ago, I was having some issues getting cleanly into 2nd on my 5MT, so I drained it and refilled with Subaru Extra-S. This worked well for maybe 5K miles before I started getting a grind going into 4th anywhere over 5000 RPM. After reading about "the cocktail" on various forums (particularly NASIOC), I decided to give it a shot and ordered it from Grimmspeed, since they had it all as one convenient purchase.

    So out came the still clean looking Extra S and in went the cocktail. After two weeks of driving around on the cocktail, not only are shifts much smoother overall, but I can shift into 4th at over 6k without even a hint of grind!

    Thanks Grimmspeed!


  9. What a difference

    Posted by Alex T

    Just put this in my 2007 WRX and its like night and day. The shifting is so much smoother, and I no longer have that grind going from 3rd to 4th. I will just have to see how it does after some mileage.


  10. It's good

    Posted by wally

    This is great I can feel the difference in the lgt. Only flaw is that every forum states that its better to use the heavyweight over the lightweight maybe grimmspeed should clrify or change their products or make it an option to get the heavyweight other then that it's great
