Red Line 75W140NS carries the extreme pressure additives of the 75W140 GL-5 but leaves out the friction modifiers, so nothing in it makes a synchro or a clutch pack slip. The one-gallon jug covers most single-vehicle services without buying loose quarts. Sold as a case of 4 one-gallon jugs.
Key Features
- Contains extreme pressure additives like the 75W140 GL-5, but no friction modifiers to balance slipperiness
- Popular for historic and vintage transmissions, including mid-1930s to early-1950s synchro-equipped gearboxes
- Helps with noisy or rough shifting in A-833 Dodge and Plymouth four-speed transmissions from 1964 to 1969
- Can be mixed with 75W90NS or MT-90 to raise viscosity in noisy transmissions
- Used in clutch-type limited slip differentials in racing for maximum lock-up
- Non-corrosive formula, safe for use with all synchro materials
- Carries the same extreme-pressure additives as Red Line's 75W90 GL-5 gear oil
- No friction modifiers, so the fluid stays non-slip for synchro engagement
- Helps slow the synchro for easier shifting across a broad temperature range
Applications
Red Line lists it for historic and vintage transmissions, including mid-1930s to early-1950s synchro-equipped gearboxes in cars and trucks, and for noisy or rough shifting in A-833 Dodge and Plymouth four-speed transmissions from 1964 to 1969. Also used in clutch-type limited slip differentials in racing for maximum lock-up.
