    Just an average conventional product
    By  Mike,  a  Verified Buyer  from  NJ  on  April 03, 2018
    I was hoping to get a nice transmission oil. But after changing to this one. Shifting became more rough. Feels like it turns thinner when it picks up temperature. But I do like very much signature series diesel oil and differential fluid is great. And I wish amsoil had some kind of high end of transmission fluid.
    Bottom Line
    No, I would not recommend this to a friend.
