Signature Series ULVBy MARK, a Verified Buyer from Tennessee on June 06, 2025After 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!Bottom LineYes, I would recommend this to a friend.Was this review helpful?

Excellent ULV FluidBy RICHARD, a Verified Buyer from Cleveland on June 01, 20252025 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!!!!!Bottom LineYes, I would recommend this to a friend.Was this review helpful?
