    Red Line Oil 50304 Details

    MT-90 75W90 GL-4 Popular in Nissan, Toyota and Mazda manual transmissions and transaxles as well as other selected applications, this is a 75W90 GL-4 Gear Oil that's slightly heavier than MTL. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting.

    Red Line Oil's MTL and MT-90 are designed to provide excellent protection and improved shiftability for manual transmissions and transaxles, having cured the problem of hard shifting in thousands of transmissions with shifting troubles. How? They have the appropriate coefficient of friction for most manual transmission synchronizers (many gear oils, engine oils, and ATFs are too slippery for proper synchro engagement). And, the wide viscosity of MTL and MT-90 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 is a thicker 75W90 version of MTL. The shear stability and oxidation stability of these products are excellent, thus the physical characteristics of Red Line MTL and MT-90 will change little with use.

    Red Line Gear Oils & Manual Transmission Fluids

    Red Line Gear Oils and manual transmission fluids are designed to give improved gear protection at high temps. They reduce differential temps 10-70°F. Efficiency improvements between 1-5% are typical. The synthetic base stocks and additives allow the gear oils to carry higher loads compared to petroleum lubricants. Try Red Line manual transmission fluids in your vehicle.

    Rated 5 out of 5 by from Excellent product! I changed oil in my TJ transmission using Redline MT-90 and can't believe the difference it made in how smooth my transmission now shifts. A buddy of mine did the same in his FJ-40 and most all of his transmission issues fell away. You can't beat Redline for their quality of oil and additives! I would recommend MT-90 for anyone changing the oil in their manual transmission.

    Rated 4 out of 5 by from smoother shifts Maybe its all in my mind, but I did diff and trany change, and with this trany fluid it does feel smoother with shifts, but still keeping that notchy shifts I like. Little pricy so it better be good, if it was cheeper it would be 5 stars, but still free shipping is the best!

    Rated 5 out of 5 by from Great product Great product. Had problems shifting my AX-15 trans in a 327 CID motor swap with Royal Purple in it. Red Line made all the difference in the world. Shifts a lot smoother, both up and down. Highly recommended for the AX-15 trans.
