    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.
