Red Line transmission lubricants and fluids provide excellent protection for your car, under both street and track use. We carry the most popular formulations to fit your particular application:

MTL (manual transmission lube) - a 70W80 GL-4 gear oil for use in manual transmissions on both street and track. Provides excellent protection of gears, synchronizers, and bushings. Shifts well when cold and allows for fast shifts when warm. MTL has the appropriate coefficient of friction for most early BMW manual transmission synchronizers (many gear oils, engine oils, and ATFs are too slippery for proper synchro engagement). The wide viscosity of MTL allow proper shifting over the entire temperature range which the transmission will experience. The synthetic base oils used have a very high viscosity index which provides relatively constant viscosity as temperature changes. MTL is a low 70W at very low temperatures and a high 80W, nearly an 85W, at elevated temperatures, providing adequate viscosity to prevent wear and deaden gear noise.

MT-90 - A 75W90 GL-4 gear oil recommended for use in manual transmissions on the track (excluding '06+ Xi manual transmission). Provides excellent protection of gears, synchronizers, and bushings at higher temperatures. MT-90 is a thicker 75W90 version of MTL. The shear stability and oxidation stability of MT-90 is excellent, thus the physical characteristics of Red Line MT-90 will change little with use. Not recommended for street use in cold climates.

D4 ATF - D4 ATF also provides a GL-4 level of gear protection, making it a superior product for BMW manual transmissions from 1993 onward and all automatics. The balanced frictional characteristics provide smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum ATFs allows high-temperature operation without varnishing valves and clutches which leads to transmission failure. It’s stability allows high-temperature operation without varnishing valves and clutches. Also provides improved shifting in cold weather.

D6 ATF - Red Line D6 ATF satisfies the requirements for BMW's modern ('06+) Xi manual transmission. This transmission requires consistent, low-viscosity fluids that are shear-stable.
It provides the best low-temperature shiftability. Also satisfies API 70W/75W GL-4 gear requirements

Racing ATF - Designed for use in racing automatic transmissions which need the positive shift of a Type-F automatic transmission fluid, Racing ATF contains no slipperiness additives, producing faster shifts and quicker lock-up, and can reduce elapsed time in drag racing. A higher viscosity compared to conventional Type-F transmission fluids provides higher torque converter efficiency at higher temperatures and the enhanced extreme-pressure protection provides five-times better film strength when compared to petroleum ATFs, reducing gear and clutch wear considerably.

MT-85 - Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper syncro engagement). Excellent gear and syncro protection, balanced slipperiness for easier shifting in cold climates. Safe for brass syncros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage. Recommended for GL-1, GL-3, and GL-4 applications, as well as where most special synchromesh fluids are specified. Compatible with petroleums and other synthetics.
