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!

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

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

Red line is the only ones, that on their website, they state their product, this product, works properly for the Hyundai 7 speed DCT. I haven't had the time to try it yet. 2/8/26 I drained for about 1/2 hour the old Hyundai fluid out of the lower bolt then replaced it on the transmission and put in 2.1 quarts, just so a just a little seeped out, of the side check/fill hole my 2021 Kona Limited with 38,000 miles replaced. And it works superb now it shifts like it should, like my wifes 2020 Kona Ultimate 24,000 miles, smooth and firm. I am quite relieved and happy so far.

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.

Great product use it in a 2018 Toyota Corolla im 6 speed manual transmission. No grinding noise between shifts and very smooth.

Not cheap but well worth it, had transmission oil changed on my manual 2011 Corolla at my local Shop , they put in GL5 as recommended by Toyota dealership, after change vehicle was shifting rough into third especially when it was cold, got the shop to put this stuff in, shifts like a dream now, very smooth, shifts even better than before, definetly recommend this stuff.

Proper oil. Showed up and works

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