MotulGear 300 75W90 100% Synthetic Gear Oil, High-Performance Transmission & Differential Fluid Oil, 1L Bottles, 2-Pack (105777)

whats not to love? Reputable and very very good gear oil. made my manual crosstrek transmission smooth as butter.

This stuff worked great. I used to have a clanking and sometimes tug first second and third. It’s now gone. Don’t go cheaper on fluid like I did the first time. Just buy this and be done with it and happy.

Good oil quality

car go fast

Great quality transfer case gear oil shipping was fast and it was packaged very well

If you use this for your GR Supra 3.0 rear differential just know that friction modifier has to be purchased separately and added to the mix. I used Redline 4 oz bottle to add to this. Upgrading to Motul “competition” already has the friction modifier but is 75w-140 better for tuned Supras.

My RA62 Transmission in my 2007 Lexus IS250 was grinding in second and third gear, this fluid was able to reduce the grind by 50%. I have tried Redline 75w-90NS, Amsoil Sever Gear 75w-90 GL-5, Royal Purple 75w-90 GL5, and the OEM Toyota Gear Oil Super 75w-90 in my transmission. None of those fluids could help with the grinding from 2nd and third gear, this Motul gear oil that is API GL4 and GL5 was the only fluid that took away the 2nd to 3rd gear grind and reduced the first to second gear grind on my transmission. My car has 89k miles with original clutch. This is an amazing transmission fluid and it is also very good for differentials. If you have a rough shifting transmission that calls for 75w90, I would try this fluid before any other brand since it is often less expensive and better in my experience.

I used this to replace the factory fluid in my transmission/front diff and rear diff in a 2014 Subaru WRX (5speed) at 45000 mile intervals. The factory fluid was much more worn down seeming and had more metal shavings when changed, but that could be from break in. The motul fluid was in fantastic condition when changed at the same interval. I could have kept that fluid in for another 20kmi easily.The only negative is the opening is not standard quart sized and the suggested pump WILL NOT screw on! The pump can sit in the bottle and pump though, so it still works for filling the diff. The integrated spout is great for pouring into the transmission without removing the intercooler. You'll just need a small funnel in the fill tube and can pivot the bottle next to the firewall.
