Product details
Red Line 75W140NS Gear Oil - Quart Manufacturer-listed features: • Also used in clutch-type limited slip differentials in racing for maximum lock up-some users add Limited Slip Friction Modifier in small doses to customize slippage • Popular for historic and vintage transmissions, like Mid-1930s to early-1950s synchro-equipped gearboxes in cars and trucks • Contains extreme pressure additives like our 75W140 GL-5 oil, but lacks friction modifiers to balance slipperiness • Helps with noisy or rough shifting in troubled A-833 Dodge/Plymouth 4-speed transmissions from 1964 to 1969 • Option for noisy transmissions when mixed with 75W90NS or MT-90 to bring viscosity level up • Non corrosive formula, safe for use with all synchro materials
