*by P***L on Reviewed in the United States on February 21, 2021*

One of the delivery van’s that I manage had developed a “tink” in the rear end while changing from reverse to drive, drive to reverse. So, changed the gear oil and put this in and the tink is gone.All of the gear lash has been taken up by this gear oil.
