REDLINE 75W90NS MANUAL GEAR AND TRANSMISSION OIL GL-5 - 3.8L/CS4

Designed for transmissions and transaxles: helps slow down synchronizers to facilitate shifting over a wide range of temperatures
Popular in Ferrari, Porsche, and Subaru transmissions.
Muscle Car applications such as Ford Top Loader, Muncie transmissions, Borg-Warner T-10, and Super T-10
Contains extreme pressure additives like our 75W90 GL-5 oil, but lacks friction modifiers to balance slippage.
Enhanced copper corrosion protection to prolong synchronized life.
Helps with weak limited-slip differential locking, compatible with Red Line limited-slip friction modifier to adjust slippage
Also used with clutch-type LSD in racing for maximum locking.
Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, and SAE J2360
Non-corrosive formula, safe to use with all synchronized materials.
The RED LINE 75W90NS HIGH PERFORMANCE GEAR OIL is a fully synthetic formula with ester base oils, designed for use in manual transmissions and transaxles that require GL-5 lubricants. This non-slip formula is designed to provide shear stability, less gear noise, and consistent viscosity. Extreme pressure (EP) additives allow its use with hypoid gears, but the lack of friction modifiers results in less slippage for proper synchronizer operation. A friction modifier can be added or used to customize the operation of the limited-slip differential.
