    By  TIM,  a  Verified Buyer  from  Northern California   on  May 29, 2026
    I just did my first service on my Ford Raptor. I have a 10R80 transmission and the AMSOIL completely cured the trippy shifts. I’m looking forward to changing the fluid in my Honda. Although I didn’t receive my free tire gauge.

    Changed the Transfer Case using AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid at 30K, time will tell. The pouch container worked out very well.

    By  JAMES,  a  Verified Buyer  from  Ohio  on  May 26, 2026

    Excellent product
    By  DOUGLAS,  a  Verified Buyer  from  Alabama   on  May 21, 2026
    Recently did a transmission fluid and filter change along with a new Banks pan. Using the Amsoil ULV transmission fluid made this job much easier. The fill plug on my 2023 GMC 2500HD is not real easy to access. But the crushable fluid packs from Amsoil really helped in replacing the fluid. It is also a very high quality fluid that helps keep the transmission temperature down. I would highly recommend this product.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  JAKE,  a  Verified Buyer  from  Massachusetts  on  May 18, 2026
    Changed the transmission fluid and filter at 35k miles in the GM 10l80 with this fluid. Going to change it again at 50k to get the rest of the fluid out. So far it has been running fine and shifting good (only at 36k miles so far). Looking forward to see how it goes.

    Superior ULV
    By  PHILLIP,  a  Verified Buyer  from  Cleveland, Ohio   on  April 30, 2026
    2019 f150 5.0 10R80 transmission. Drain and fill with OEM replacement filter and filter seal. Replaced plastic factory pan with PPE standard depth pan. Collected all fluid that was drained including trans cooler. ( collected 9 quarts) Was able to replace approximately 9.75 quarts for proper fluid level @ 210 degrees F. Cleared transmission adaptive tables utilizing Autel tool. Performed drive cycle relearn procedure as close as I could. Have been driving truck in Tow haul mode in stop and go traffic and in Normal mode on highway. Unbelievable difference in transmission performance. Transmission operates better than new.
    Bottom Line
    Yes, I would recommend this to a friend.
