Works.
Honestly can any of us really review this product? Without doing an oil analysis after thousands of miles I can’t tell you if it’s good or not. What I do trust is the brand, I know the fluid is the right spec and I liked the price. That’s what I bought it. I’m using it for DOT III power steering fluid if that matters.

2005 Honda Odyssey Touring
I used this for the transmission fluid flush on my 2005 Honda Odyssey Touring with 221k miles. Unknown when last transmission fluid change was, but it's part of Honda's maintenance schedule - so ~30-60k miles. I ran this fluid for a few weeks (~500 miles) before flushing it out and putting in the Honda OEM ATF. In the Odyssey, you cannot drain all of the fluid out the first drain (some left in cooler, lines, solenoids). The recommended total "flush" is to fill/drain 3x times (I only did 2x). On the 2x fill I used the Honda OEM ATF, since the cost is reasonable for my budget. I cannot tell a difference in shifting/drive-quality between Honda OEM ATF and this.

Proven tough through extreme personal use.
I am retired from the countries largest delivery services. I had to provide my own personal vehicle and daily my vehicle would stop and start well over 800 times. Under this punishing year round service, my transmission lasted for 13 years in one vehicle. With maintenance (change your fluids) I am convinced, from personal experienced this is the best DEX/MERC ATF fluid on the market.
