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.

this is Grimmspeeds instructions for the oils to use and amounts.

Just wondering if anyone has had success with this fluid on longevity and performance.

Thanks guys!
