Red Line Oil's MT-90 transmission gear oil is designed to provide excellent protection and improved shiftability for manual transmissions and transaxles. 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. It provides excellent protection of gears and synchronizers, and its balanced slipperiness provides a perfect coefficient of friction, allowing for easier shifting.

Redline GL 4 MT 90 does the job

Summit RacingSummit Racing Verified Purchase

Bottom line is that there are few straight GL 4 gear oils, and there are several transmissions that are there best only with that grade gear oil. For my NV4500 and, especially Toyota R150, shifting is much smoother, operation quieter, and I anticipate longer service life.

Redline mt-90 transmission gear oil 50304

This stuff is awesome. Well worth the cost of admission. I was using mobile1 in my manual transmission and was having some hard shifting issues. I read some reviews on the redline MT-90 and decided to try it. It was the best thing I've done. my car, 2004 scion xb, has 200k miles on the clock. I can honestly say since switching out to MT-90, the car shifts better than it EVER has! I was so pleased, a good friend of mine changed over as well with the same great results. The only downside is that you have to order it but with shipping as fast as what summit offers it's really no big deal. ...read more

By far the best manual trans fluid

Summit RacingSummit Racing Verified Purchase

I have tried many other transmission fluids in my Evo, but this one is for sure the best and makes the shifting very smooth.
