    Awesome
    By  TONY,  a  Verified Buyer  from  South Carolina   on  March 21, 2025
    2021 Silverado 1500 8L90, 97000 miles. Had a heavy shudder in transmission, torque converter slipping, RPM’s up and down while driving. Took truck to transmission shop and was told truck needed new transmission and torque converter. $6000 estimate. After researching the issue, changed filter and fluid to the Amsoil fluid. Solved every issue I was having. Transmission performs better, shifts smoother than when I purchased the truck new from the dealership. Made a believer out of me. Amsoil will be the only fluids I put in my vehicles from now on.
    Bottom Line
    Yes, I would recommend this to a friend.

    Fixed Transmission Issues
    By  BRIAN,  a  Verified Buyer  from  Alabama  on  March 16, 2025
    Use this in our 2013 Elantra with 152,000 miles. Now, no more hard shifts. Excellent Amsoil product as always. I've been a returning customer for many years now for all Amsoil products due to results just like this.
    Bottom Line
    Yes, I would recommend this to a friend.

    The best and worth ot
    By  LANNY,  a  Verified Buyer  from  California   on  March 12, 2025
    Check compatibility, fill your transmission and know you have the ultimate protection. Towing a travel trailer and being a mechanic, I have first hand experienced the smooth shifting with less clutch disc material on the magnets and filter between changes. The extended intervals alone make this a best value for the money.
    Bottom Line
    Yes, I would recommend this to a friend.

    10R80 runs smooth
    By  SAUL,  a  Verified Buyer  on  March 11, 2025
    I used Ford's ULV at 30k miles. The trans runs good but every once in a while the trans would have hard shifts. I drained and filled with Amsoil's ULV at 47k miles. I immediately noticed the difference in shifting. I think the 10R80 really likes Amsoil. I've ran the Amsoil ULV for about 2k miles and have not had a hard shift with the trans. At 60k miles I'll be dropping the pan, change the filter and loading with Amsoil ULV.
    Bottom Line
    Yes, I would recommend this to a friend.

    Fuel milage increase
    By  BRIAN,  a  Verified Buyer  from  Oklahoma   on  March 11, 2025
    I performed an entire Amsoil fluid swap on my truck of 150K miles. It took no time at all to see a 2.5 mpg increase in fuel savings. Will recover the cost of the fluid changes in a short amount of time.
