Jube transmission flush

[ed1]

Transmission fluid looking a little milky! I know I need to get tractor warm and drain fluid, flush with diesel fluid and replace with 134D. Should I use a gallon of diesel and run it a couple minutes and then replace fluid. Also rear differential, 90wt gear oil?
Thanks,

We put UTF in the transmission, hydraulics and rear axle of our Ford 641.

134D is the Ford spec for UTF

I would just put the UTF in all three sumps. Like was pointed out to me a few years ago, how do you know the seal between the differential and hydraulic sump is good?
