Designed for transmissions and transaxles - helps to slow synchros for easier shifting across a broad temperature range Popular in Ferrari, Porsche and Subaru transaxles Muscle Car applications like Ford Top Loader, Muncie transmissions, Borg-Warner T-10 and Super T-10 Contains extreme pressure additives like our 75W90 GL-5 oil, but lacks friction modifiers to balance slipperiness Improved copper corrosion protection to prolong synchro life Helps with lock-up on weak limited-slip differentials-compatible with Red Line Limited Slip Friction Modifier for tuning slippage Also used with clutch-type LSDs in racing for maximum lock up Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E and SAE J2360 Non corrosive formula, safe for use with all synchro materials
Since most GL-5 gear oils for differentials are too slippery for manual transmissions, Red Line offers these products that ensure proper shifting while providing ultimate wear protection
