Full Synthetic 75W140NS GL-5 Gear Oil contains extreme pressure additives like our 75W140 GL-5 oil, but lacks friction modifiers to balance slipperiness. It is popular for historic and vintage transmissions, like Mid-1930s to early-1950s synchro-equipped gearboxes in cars and trucks. It helps with noisy or rough shifting in troubled A-833 Dodge/Plymouth 4-speed transmissions from 1964 to 1969 and is a good option for noisy transmissions when mixed with 75W90NS or MT-90 to bring viscosity level up. It is 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. These Red Line GL-5 offer big protection but are not slippery, for certain trans and diff applications. These GL-5 products contain the extreme pressure additives necessary for ultimate protection road cars and racing vehicles, as well as friction modifiers for proper limited-slip operation. This product exceeds API GL-5 specifications and is engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear.
