i did a full fluid flush being , front diff , engine oil , transmission, t case , rear diff .
the fluid quality is out standing as for the truck now runs and rolls like new and much more quiet as before. it’s clearly more happy that it was now that all fluids are done.
the g56 manual trans shifts like new now and it’s got 140k on it .
highly highly recommend AMS oil. i need to do a coolant flush next so if they sell coolant i will be buying it soon.
10/10 stars
