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

We use this in racing transmissions and the stuff is great.

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.

Worked great in STI 6 speed trans and differentials.

Love motul. Quality oil, even the cap/spout is thoughtfully designed

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

I was having some trouble with my Subaru BRZ's transmission with hot temperatures and on the racetrack. The transmission would have a really tough time going into first gear from a stop after the transmission got hot (even during a regular commute to work), and on the track it would grind the synchros from third to fourth during quick shifts. I had heard that the factory fluid is kind of garbage, so I went with this as an upgrade. It mostly eliminated the hot first gear issue, and I have had no grinding at all with quick 3rd/4th shifts (albeit I haven't been back on the track yet), so I would definitely say I am pleased with this fluid. If you still have the OEM transmission oil in your 86/FRS/BRZ, think about switching it to this stuff.

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.

Used this in our gf4a force 4 speed and came recommended by techs at g force. My driver said seemed smoother shifting and came out like new after an intense road course event. Highly recommend.

After reading about this product on a RZR forum I decided to try it in my machine. Immediately I found its shifting from Forward to Reverse smoother and seems quieter from the OEM oil which I had used previously. Great product.

Excellent product, as expected.

My 1997 Suzuki Sidekick has been run with 32" tires for many years and the manual transmission was pretty rattly. This oil quieted it down significantly and although there is still wear in the transmission and it will rattle if you "lug" the engine (too high a gear for the speed), it's a LOT better. Yellow metal compatible too, so it won't eat my brass synchros. Motul for the win!

The best there is.. the best there was... and the best they ever will be
