Used this in my 3rd gen 4runner. Since they don't make dexron III anymore, I did extensive reading online seeing what is a good replacement. Some say dexron VI is backwards compatible, but being that my truck is almost 15 years old, I didn't want to risk it. I also read that dex/merc is the best replacement for dexron III, and works well. Figured I'd give it a try. Replaced a gallon's worth of transmission fluid and 1000 miles later, I have had no problems with my transmission, in fact it runs slightly smother. Just make sure not to overfill!

Dip stick on my 1997 Lexus ES300 states Dexron II and after doing some research on internet i found that this ATF is perfect replacement. I did a drain and refill. So far my car is working perfect. It was shifting smooth before change as well as after change. At 220K miles (last ATF was about 10 years old and i never cared to change). Now since i purchased a siphon pump which makes it super easy to suck old fluid out from dip stick area and put new fluid as well as car kept on working flawless so i thought i should proceed with change now. It is a done deal. All good so far. Likes that in less $20 transmission has received some good oxygen that should keep it working for some more time.

I used this trans fluid in my Chevy K20 for my turbo 400 when I did a filter and fluid change, works great and have had no trouble.

Replaced the transmission pan gasket and filter in my 1988 190E 2.6L and filled it with transmax and shifts smoother and car feels 10 times lighter now!

Used as power steering fluid for a 1997 BMW Z3. The instructions say to use ATF only and the forums recommended this one.
