I had to wait some time for the oil to be back in stock, but it was worth the wait. I was experiencing issues with my 4th gear; it didn't always slide smoothly into place when downshifting. However, using this combination of fluids completely resolved the problem. What I initially thought might be a more significant issue turned out to be fixed by simply changing the fluids.
The 6MT in my 08 Legacy Spec.B has some syncro issues, and it grinds any time I go into 3rd or 5th. I know I need to rebuild it eventually, but I just don't have the money for it right now. In the meantime, I bought this cocktail and put it in, and now the grinding issue is nearly gone and shifting feels tons smoother in general. It definitely still grinds a bit if I really jam it into gear, but it seems significantly happier in general. Had a friend recommend this to me, and I was pretty skeptical about it, but it definitely made a huge difference on mine! Very happy with this purchase!
I changed my transmission fluid on my 2016 STI with this cocktail. The transmission used to grind into fourth gear if you even thought of shifting to fourth. Now it’s super smooth!
fixed the grind from 5th to 4th and 3rd to 4th in my 500whp 2018 sti!
It’s great! Smoother drives, especially with the new clutch
