Full Synthetic 75W140NS GL-5 Manual Transmission Fluid - 946mL | RLO57104

• Contains extreme pressure additives like our 75W140 GL-5 oil, but lacks friction modifiers to balance slipperiness
• Popular for historic and vintage transmissions, like Mid-1930s to early-1950s synchro-equipped gearboxes in cars and trucks
• 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
• 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
• Non corrosive formula, safe for use with all synchro materials
• Fully-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions
• Ester base stocks and friction modifiers (except NS) provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
• High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change
• Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils

Suitable replacement for:

• API GL-5 & MT-1
• MIL-PRF-2105E
• SAE J2360
• Historic & Vintage Synchro Transmissions
• Rockwell 0-76-C
• Used in SAE 140 Applications
