Closest fluid I can find for my diff is 5 gals of the NAPA brand TO-4, is this going to work ok in my SV200? Will 5 gals fill the diff housing?

Thanks.

It will work, 5 gallons should just do it 4.75 gallons normally

Amsoil powershift is very good in 30 or 50 weight
Cat T-04 also works well in 30 or 50 weight

We have found the steering response slightly better with the amsoil

Is Cat the only place to buy Cat T-04 oil from?

….. there's lots of companies that make a ''compatible'' TO-4 oil, but CAT was the first to ''spec'' it out , in a broadband useage…. has great ''inhibitors'' to guard against pump wear...

Also, Both the Amsoil and the Cat fluids both have friction modifiers which, in the off brands I’m not sure.

It’s kind like beer, you know there’s beer,then there’s BEER! They are all beer but!
Some are just better beer:smile:Don’t me started on Snowcats!!!!

you can also use John Deere's HY-Tran tractor hydraulic and transmission fluid for the same reasons Brad mentioned. Use the best oil you can get and stay away from "off brand" oils. They will ultimately cost you.
