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

Thanks to Amsoil, the only mfr I could find with a definitive/ suitable substitute for the overpriced Mopar fluid. Excellent !!

My car transmission was slippery and I change oil from dealership and not working that oil too than I order amsoil it’s best and it’s fixed my problem

Did a transmission flush and filter change in my 18 Tacoma using 12 quarts of AMSOIL signature series ATF and wow. I’ve used other quality products in past in the same manner but this ATF made a noticeable difference in smoother more responsive shifting. Never used it before now, and it will be my go-to from now on.

My Silverado 10 speed shifts way smoother and runs cooler since swapping to the amsoil ulv fluid!

Been using amsoil for several years in everything I own. Great oil

Great product.

Another great product from amsoil. Wish it was cheaper but I still want it

Fast shipping, great packaging. Truck runs great.

My 2007 ML350 purrsss a lil less and more appealing to listen after a transmission fluid change. Definitely getting peace of mind after using an Amsoil product.
