do a search on mt 90 and royal purple. people will tell you RP is where it is at. I did my trans fluid this weekend and the RP stopped my 3>4th grind and made the 4th gear syncro quiet down. Amsoil and MT 90 i had ran b4 w/ no success. And with the price only being 8/qt, I bought mine for 8.99 qt locally, its not a big deal. after u figure shipping on most oils it doesnt matter. I now understand why people praise it. search people, and you shall see.
