Customer Ratings & Reviews

Amsoil Signature synthetic ATF lowered the operating temp of the transmission in my 2016 Silverado.

I replaced my original fluid at the 40k interval with great results. Runs smooth and would recommend for a transmission fluid upgrade.

Just put this in my 2011 Ram 68RFE, shits so smooth now.

👍

My 2016 GMC Yukon Denali started shuttering at 57k miles and it’s been perfect since and just did a dump and fill at 155k so I know this stuff works and it’s the best trans fluid there is in my book

Used this on my old Honda pilot with 200k it cleared up stubborn and hard shifting easy to use and survived hard towing would recommend.

I know… warranty intact. But if the OEM says it failed due to the fluid, you may be out of a vehicle for months while everything plays out. Even if amsoil says it’s ok, do not go over OEM specs if under an extended warranty.

Love this stuff smells like liquid snozzberries and horsepower. Real talk this is Mary K for men. I buy amsoil she gets ditzy broad stuff.

Very happy with this product

Great fluid. Light years better than factory fill junk. Buy it, run it! You won’t regret it.

After researching many different fluids for my 2019 Camaro ZL1 automatic transmission, I settled on this one from Amsoil. I must say now that I’m very happy with my choice. After thoroughly testing it out on a 1,100 mile trip which included 3 hard days running at Tail of The Dragon I was amazed at how well the trans temps stayed down. After my hardest run and fastest run on the Tail the trans temps stayed down was only 190 degrees! I’m convinced Amsoil was the right choice!

Topnotch fluids. Can't go wrong with AMSOIL. Quality can't be beat.

I run this in my car and it shifts smoothly and haven’t had any issues

My transmission is shifting very smoothly and my temps have been steady even with me running my Jeep hard at times uphills.

2025 Sierra 1500 with a 10 speed with 2000 miles, did not like the way the transmission shifted so I swapped out the fluid with the Amsoil ULV. Made the shifts much more consistent and positive like it should be. I thought this was a waste of time and probably would not work but i was proven wrong, best thing I could have done for this transmission!!!!!

Can't nothing on the market compare to amsoil. Two thumbs up and if my feet had thumbs, I'll throw them Up to. Thanks amsoil.

Oil that does the job!

My transmission is running as smooth as ever.

I use this in my Chevy 2500 HD because I plow and tow and it runs cooler temps on transmission
