Red-line Oil Mt-90 Transmission Fluid 50304

Product Description

Red Line: Synthetic Manual Transmission LubricantsRed 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. MT-90 Popular in Nissan, Toyota and Mazda manual transmissions and transaxles as well as other selected applications, this is a 75W90 GL-4 Gear Oil thatGs slightly heavier than MTL. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting. MT-90 TRANSMISSION FLUID. 1 QT.Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting.

Customer Reviews

If it's time (say every 60k)...
I would go ahead and spend the money on this product. There was not much of a difference in my transmission right after I changed the fluid, and 3k later, shifting seems only a little smoother. At about double the cost of the regular fluid, I was expecting a bit more. I wish Redline products were more widely available at my local auto parts stores, though Auto Barn did an excellent job delivering as they stated.

Redline rocks!
I've been a longtime Redline lubricants fan because of their high quality and specific properties of the products themselves. In this case, (MT-90) the key property is to provide enough friction between gearshifts to allow the synchronizers to slow down and provide smooth gearshifts. This is not an easy task to perform while still lubricating and being slippery enough to provide a consistent oil film, lubricity, resistance to thermal breakdown and long fluid life. If you have an older transmission that's getting more difficult to shift, Redline MT-90 can improve it and extend the time before a rebuild is necessary.

Great Manual Tranny Oil
My Nissan Sentra SE-R Spec V is one of those with a transmission that grinds going into 2nd. (and maybe other gears at times.) This smooths out the shifting just fine. It is really smooth and easy without any grinding.

Highly recommended!
