50604 MT-LV 70W/75W GL-4 High-Performance Full Synthetic Gear Oil Lubricant for Manual Transmissions & Transaxles - 1 Quart

The best of the best. This Manual Transmission fluid that the service manual calls for on my 2013 Scion TC is the only one that meets or exceeds manufacturer specifications. I have used other brands and they always make it hard to shift after a cold start. With this fluid even in a cold start the transmission feels smooth as butter and makes it harder to miss-shift. I have been using this on my car for the past 5 years and have had no issues.

I was looking for a high quality oil for a long time, not mass market. I filled it into my transfer case and the jerking is gone. Everything works great now.

Used on 2018 Toyota Tacoma great quality

A perfect replacement in my 2022 Toyota Tacoma , no problems at all!

Best price I could find on internet. As good as Toyota brand transfer case fluid, at much less price.

I changed my transfer case fluid This fluid meets the exact Toyota spec for TC fluid for a 2023 Tacoma V6 4WD High quality fluid Engages 4WD smoothly and faster

Red line is the only ones that on their website, states their product, this product, works properly for the Hyundai 7 speed DCT. I haven't had the time to try it yet.

From what I can tell this is the correct lubricant and it is a direct replacement equivalent for the Toyota differentials and Transmissions. Toyota wants triple the price and from what I have seen this product meets or exceeds all specifications so you might as well use it I did and I have no problems

Great quality product. I used on my 4Runner and Tacoma transfer cases, perfect substitute for oem stupid expensive fluid. 100k+ km with zero issues.

Used for a 2021 Elantra N-Line with the DCT and it worked great! Product arrived thoroughly sealed and on time.

Proper oil. Showed up and works

Meets OEM toyota transfer case oil at a fraction of OEM toyota oil. My tundra shifts in and out of 4x4 without issue.

Perfect for transfers on 4runners and Tacomas.
