Customer Ratings & Reviews

Great product recommend it worked out very good for me. I'm going to use it on all my other cars and trucks. 2020 Silverado Truck was shuttering pretty bad and when I flushed it out with a ams ATF oil it went away.

After switching to amsoil transmission shits and drives smoother

Removed transmission shutter completely recommend this for GM vehicles.

I use this fluid in Chevy Cruze diesels with the Aisin Automatic. It improves shift quality.

Transmission shifting so much better now no more jerks on light throttle inputs and that was just 1 gal of fluid swap will drive it for a while and drain and fill again with other gal. This is great stuff

I've always liked this products I used it since 2010

Testing Amsoil ATF in my 2002 F250. Over 375,000mi on truck. 200,000mi on Trans. 100,000mi on engine Truck runs great. Test are all good, then will use in my next new truck.

Testing Amsoil ATF in my Ford NP273F transfer case, and the Hydro boost with power steering system. I am ultra sensitive to changes in how my vehicles run. Rebuilt Transfer case as drive shaft runs on 3 internal bearings in the case. Runs smooth, great, cool temp. Also works great in Ford hydro boost & power steering system. Helped with smoothness & whine.

Tranny love it!

I just bought a 2018 gmc sierra with 112,000 miles. I wanted to exchange the trans fluid before I really started driving it. These trucks are known for bad transmissions. My other truck is a 2011 gmc sierra with 295,000 miles. I had done the trans fluid change a couple times and have used AMSOIL signature series 5w 30 since I bought it. It still runs and drives great. The bed is rusted away and the frame rotted out, otherwise I would still be driving it.

Works on 2020 Ford Fusion, and 2016 Honda Odyssey as well.

I put this in my Toyota Sienna at 120,000 miles and I immediately noticed that the van is shifting better and smoother than before. I was a bit nervous to not use the Toyota WS fluid but I feel confident now that this is a very compatible fluid for this van.

I started using AMSOIL products back in 2008. Since then 100% of all of the systems in my vehicles have been converted to AMSOIL products. I have used Signature Series transmission fluid in all the vehicles with auto transmissions, many that had near 200K miles on the odo and still going strong when sold.

My 22 f250 6.7 10spd started shifting erratic with only 30k miles, took it to the dealer they said that's the way it should be and did nothing. So I did a complete flush 18 quarts of ulv atf amsoil and now the transmission shifts perfect. Don't know what this stuff is made with but it works.

Really great fluid transmission shifted much smoother after changing

This transmission fluid is the best I have ever used. Immediately noticed a huge improvement!

I just changed my transmission fluid about 6000 mile ago so I didn’t change my filter. I just drained it and put this in. Honestly it shifts smoothly I pull a 10 thousand pounds of trailer and hay 2 times a week sometimes 3at 50 mile drive. . Temp on my transmission dropped about 5 to 7 degrees. I will change it again in the spring and put a new filter in it. So far I love it.

Second recent purchase. Done a drain and refill on both mine and the wife's vehicles. She knows zero about vehicles but said she's noticed smoother quieter shifting in her 2013 Camry

I use all Amsoil fluids in my Dodge Ram 3500. Truck runs great !!!

Like the rest of the Amsoil line up, it’s awesome! 2011 duramax.
