Great experience
Dealership gave me the wrong fluid twice and said they couldn't order the correct fluid so we just went aftermarket. Fluids came fast and in good condition. Car shifts much better now

Used in my G35 manual transmission
I’ve changed it at least 3x in its lifetime with this same fluid. Works well when the temps drop below 30F

Great Fluid, But The Non-Standard Bottle Proved to be an issue for me.
Great Product. It's very difficult these day's to find an ester based straight GL-4 synthetic. None of my Local Auto Part's stores even carry a fluid with these specifications. This product Matches the specifications on my Nissan exactly. The notchy Shifting went away, the winning noise when cold went away. This fluid did exactly what i was hoping it would. However i am not willing to give it five stars for one main reason. The non-standard bottle. Since the fill plug on my Transmission is difficult to access, i had to purchase a transfer pump. Most of the hand pumps you find at Auto Parts stores are designed to screw on to the top of a standard gear oil bottle. None of them would work on the RedLine bottle. So i had to go to the hardware store and buy extra fittings and vinyl tubing in order to modify my Pump since i did not have a spare Gear oil bottle around to use. I used a one gallon washer fluid jug after cleaning it out to avoid contamination, and i was able to attach my pump to that with some Minor modification, I put all 4 quarts in that container and then into the Transmission in one go, So it did work out in the end, but this is extremely annoying. Why can't RedLine just use a Normal Bottle like everybody else?
