Lexus rx350 2014 138k miles.
My. Ar was over shifting/under shifting and shuddering at times in gears 2/3/4. I did a drain and fill with fill and the improvement was remarkable. I'll do another in a few hundred miles. Amsoil saved the day.
Bottom Line
Yes, I would recommend this to a friend.

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
Bottom Line
Yes, I would recommend this to a friend.

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.
Bottom Line
Yes, I would recommend this to a friend.

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.
Bottom Line
Yes, I would recommend this to a friend.

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.
