Let me ask another question, the bottom line that goes from the gear set to the pump, is that a return, or is that where the fluid is pulled from? could a transmission cooler be plumbed into that line? or is my thinking off? the hydro I have is off a 147 it has a place on the top of the pump for a hydraulic lift, could a cooler be put into that line and then returned to the trans?

Yeah it basically "is what is is." It is being used for what it is designed for. A bigger tractor needs a bigger hydro unit. There aren't any internal modifications you can do to improve it for this. The bottom line is not the return; it's the suction line, so don't put an oil cooler there. If you open up your service manual, there's a great picture that shows how everything works and how the fluid is routed.
I suppose you could put one in where the ports are on the charge pump, but if your pump is actually from a 147, it doesn't have those. The best place to put the cooler would be between the exit of the hydro unit and the transaxle, as that's where the fluid is the highest temperature, but after you study the diagram in the manual you will see why that is impossible.
The pullers put 60+ hp through their modified clutch setups, so I'm sure you could come up with something that would work.
What exactly to you plan on doing with this thing, anyway?
