Red Line 75W140 GL-5 gear oil is a high-viscosity lubricant containing additional friction modifiers for compatibility with clutch-type limited-slip differentials, recommended where GL-5 protection is needed. It is not intended for most manual transmissions or transaxles with synchronizers due to slipperiness that can impair shifting. For many LSDs, no extra friction modifier is required, and it meets API GL-5 and related specifications.
