Customer Ratings & Reviews

My 2017 Fiat 124 Lusso has a 6 speed Aisin Warner B400 transmission that the dealer couldn't fix. I changed filter and Fluid over to Amsoil Synthetic ATF and my problems are cured. The motor loves Amsoil synthetic motor oil also.

I read the reviews and didn’t believe it but they are true , my truck shifts smother and gets better fuel mileage. Absolutely love Amsoil products

Good product first time I use and very satisfied with the results

Changed out and the transmission fluid and shifts like it was new!

I just bought a 2012 Toyota Camary. It had a harsh vibration when the transmission was about to downshift. I did a complete transmission fluid change and changed the filter and used amsoil transmission fluid and the transmission shifts like it's brand new again. I will be using this in all my cars for now on.

I was hesitant to use this in my Honda Civic because Honda claims that only their ATF will work...Not so...not only did it work but, it fixed my shifting problems

Got this for my 2019 Ram 2500 6.7 Cummins. It was time to change the fluid in my 68RFE Transmission and I wanted to use Amsoil . I wanted a Syntheic fluid because it’s better and last longer than the average ATF fluid.

The best way that I know to extend the life of any automatic.

Better the mopar $65 a quart!!!

I use nothing but amsoil in my antique car. I find it runs smoother and cooler and now shifts smoother.

Used it in all my transmissions Awesome

Its nice

Shifts smoothly after complete 12 qt change. Best fluids ever

Bought this fluid to solve some issues with the cheap factory oil they put in Ram Trucks. Amazing!!!

Excellent

Installed Amsoil synthetic ATF in my 2008 Hummer H3A. Transmission is shifting smoothly and positively. No issues whatsoever, as expected.

Drained old oil, filled with fluid and fixed, slight hesitation and slow shifting of gears in a Acura TL. New to me car 167k, the difference before and after was honestly amazing. I expected it might help but there was an immediate difference. It's been over 1000 miles since, still shifts are still smooth and quick.

I bought this twice so I could flush out system. So far everything seems fine.

I had purchased this transmission fluid to do a drain and fill on my wife's '06 highlander hybrid. Based on the seat my pants dyno it feels smoother. Need a bit more time to see if there is any significant change in fuel economy.

With 80,000 miles on my tans behind the new 540 HP 6.2. The trans is shifting smoother and more solid than ever before. It’s funny but true I am getting about a mile more per gallon. Trans is running cooler so hopefully we will get a full life out of the trans
