Red fluid in power shift?

Jrideman, I doubt it really is automotive transmission fluid. I suspect someone used Cheveron Tractor Hydraulic Fluid which is a red colored oil. I worked as a construction equipment oiler for a couple of construction companies and this was a common oil used in a lot of different brands of equipment's hydraulic and transmission systems and even differentials. Just drain it and put in what you know to be the correct fluid. W. SMITH

Thanks for the input. I found a mobil 30w that meets the TDTO standard for 7.77 a gal. I also could not find the gaskets for the pinion cover so I orderd some buna rubber to make my own. This is my first cat tractor and am learning fast how great this fourm is for info.
I almost forgot to ask if anyone knows how long the dip stick for the clutch compartment should be? It has been discontinued from Cat.
