Red Line GL-5 Gear Oil is designed for transmissions and transaxles. Will help to slow synchros for easier shifting across a broad temperature range. Popular in Ferrari, Porsche and Subaru transaxles. Musclecar applications like Ford Top Loader, Borg-Warner T-10 and Super T-10, and Muncie transmissions. 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.
