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

EXCELLENT FOR - high- and low-mile transmissions, gear protection, synchro protection, and balanced slipperiness for easier shifting in cold climates POPULAR GEAR OIL FOR - historic and vintage transmissions, like Mid-1930s to early-1950s synchro-equipped gearboxes in cars and trucks, 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, Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, and SAE J2360 WHY RED LINE - Established in 1979, Red Line Products perform & protect better than any on the market.
