Red Line Oil 50604 Gear Oil MT-LV SAE 70W, 75W —0.95 L (1 Quart)— Full Synthetic Oil for Manual Transmissions GL-4 Ideal Mercedes 235.10, Dodge/Fiat BOT 350 M3, GM BOT 303 mod, Toyota/Scion LV, Audi

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.

I purchased this for the transfer case in my 23 Tacoma. I got tired of the dealers high prices & Redline is one of the best product around. Shipping was quick & price was right.

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.

This product is a must. Changed my DCT fluid at 63k km and it now feels like a new car. I wish I had some this flush when I was at 30k km. No slips while driving car is super smooth I don't hear my gears engaging or stressing while I'm in bumper-to-bumper traffic. Anyone with a DCT knows how it is while stuck in traffic!

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