    100% recommend
    By  JOE,  a  Verified Buyer  from  SE Wisconsin  on  December 13, 2024
    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.

    Smooth Shifting
    By  JOHN,  a  Verified Buyer  from  NJ  on  December 13, 2024
    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.
    Bottom Line
    Yes, I would recommend this to a friend.

    Trans Oil for long life
    By  MARK,  a  Verified Buyer  from  Michigan  on  December 10, 2024
    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.
    Bottom Line
    Yes, I would recommend this to a friend.

    2022 f250
    By  BRIAN,  a  Verified Buyer  from  Florida  on  December 10, 2024
    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.
    Bottom Line
    Yes, I would recommend this to a friend.

    ATF
    By  TONY,  a  Verified Buyer  from  Utah  on  December 02, 2024
    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.
    Bottom Line
    Yes, I would recommend this to a friend.
