Harold - good catch! RedLine does make a GL5 Gear oil called 75W90NS - from their product list: "75W90 NS - a GL-5 which does not contain the friction modifiers for limited-slip hypoid differentials. This makes the transmission synchronizers come to equal speeds more quickly, allowing faster shifting and much easier low-temperature shifting. " Although they state that they recommend the MTL for most transaxle applications, this is the only product that would seem to fit the GL5 spec. Thanks!
