NAA hydraulics wouldn't work so I decided to change oil in the hydraulic, transmission & differential reservoirs. Fluid from the trans and hydraulic drains was tan & gloopy w/ some semi solid chunks in it. Have not drained the differential yet. Tractor has set for a while. I don't remember where I read it, but I was told that UTF will be good for all three. Bought 5 gallons of Castrol UTF but thought I'd better check with the experts before I open the container. Can I use it for the trans, hydraulic and differential? Any advice is much appreciated. Thanks,

Larry

I think the Castrol UTF will do the job for you.
