Customer Ratings & Reviews

I’ve always used Amsoil ATF and have never had an issue in any of my transmissions except for one and that was not related to fluid. Multiple vehicles well over 300,000 miles. Great work Amsoil!!

The first time I ever used Amsoil ATF was when I owned a 2006 Dura Max that I bought used with 20,000 miles on the odometer. I had issues with the automatic transmission both upshifting and downshifting. I drained all fluid and put Amsoil in it and the problems were gone. Since then, I only use Amsoil products in all my vehicles, mowers, UTV's and other equipment, front to back inside and out.

Great shipping and superior product, I can’t even feel my truck changing gears after putting this fluid in.

Works great

Never skimp on quality

No funnel or hose attachment needed. Super easy to use packaging.

Great product no problems

I’ve been using this transmission fluid in my vehicles for years. Very noticeable smoother shifting and downshifting. 2018 Ford F150 10R transmission. Highly recommend this fluid for any vehicle.

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
