Customer Ratings & Reviews

Never had any motor problems in 200k miles . Only added about 1/4 quart in 20k miles.

Did a flush on my 98 ram 2500 5.9 gas and so far so good shifts way smoother. Looking forward to see how it goes long term so far I’m satisfied with amsoil products.

Replace my Mercedes Benz transmission oil and its been shifting smoother than ever. Im doing it on my remaining vehicles

I have switched most of my vehicles to this ATF. Works great for daily drivers, stop and of postal work, and put it in my hot rod cruiser too.

This truck has to last me so I might as well use the best

Only oil I use

This oil has saved my transmission twice, per the technician that rebuilt it both times. Two separate shops claimed that had I used any other fluid. It probably would have cost me a lot more to fix the damage. Both times transmission fluid lines, failed and emptied the transmission fluid all over the underside inside of the vehicle and on the trailer. This is the best transmission fluid I’ve ever used.

Great product

Just changed the transmission oil in my son's pickup and what a difference in shifting. He immediately could tell the difference and will highly recommend Amsoil products to his friends. This is the third vehicle I have changed the transmission fluid using Amsoil 100% synthetic fluid and confirm this product is awesome.

Had to replace my transmission due to it being garbage. Contacted Randy's transmission for something better and told them I only use Amsoil in my truck. They gave me a longer warranty since in use Amsoil for the transmission. Amsoil for the win again.

I trust AMSOIL over other brands, so that’s why I got this.

The best atf money can buy, and at the cost of a replacement transmission, regular servicing with top quality fluid is cheap insurance. I use this fluid as a WS alternative in my Toyota Tundra and Lexus IS , both transmissions operate better than new

Very good....

used it in my g56 transmission made a huge difference, shifts way smoother, definitely recommend it

I used this in my 19 pilot. The tranny was clunky and made the switch at 20k miles. I couldn’t be happier. I now don’t even feel when the transmission shifts. Couldn’t be happier.

What I have read, it’s a good oil,

Used this transmission fluid to replace all of the factory fluid after using Amsoil transmission flush in a 2.8l 2018 Chevy Colorado diesel at 70k miles. Replaced all the fluid and the transmission filter by draining it from the transmission cooling loop and then removing the pan. The truck shifts better than it did on day one when it was purchased new. Could not be more happy to recommend this product. Only regret is not replacing the fluid right after purchasing the truck new. What a difference. All of the clunking went away and the transmission holds the gears much longer as you let off the accelerator pedal. Usually don't write reviews unless something is really good or really bad. This fluid is really good. Love Amsoil products and their preferred Customer program.

I use Amsoil ATF in the front forks of my 1984 V65 Honda Sabre because I want the best there is period. I also use Amsoil ATF in the power steering system of my 2008 Chevy Uplander. Starting her up in -40 weather and it hardly makes a noise ! With the old power steering fluid there would be a loud whine for about 2 minutes in extremely cold temperatures. No whine and full functioning steering at any temperature.. Amazing stuff !!

Whenever I change Transmisson fluid I will only use Amsoil.

I highly recommend this ATF fluid! I have a 6T70 transmission which is a sealed unit so you only get so much fluid out doing a single drain and fill. So, I did one drain and fill, added Signature Series ATF fluid, drove it for about 200 miles, and then did another drain and fill and added Signature Series ATF fluid again. I estimated I had about 80%+ new fluid in the transmission by this time. However, I've never felt the transmission shift smoother even with 'off the shelf' fluid. It's definitely worth the price. I will never use anything else ever again!
