Your mainline pressures do not make sense, you must have the gauge in the wrong port or the valve body you have doesn't supply pressure to it. Try checking it at the front servo in 3rd.

The cooler return line pressure is fed back into the transmission for lubrication, what you're seeing is a little high. Is the converter regulator valve (the one next to the main relief valve) still functional or has it been locked out?

904's don't normally take out the thrust due to the smaller diameter converter neck, much easier on things than a 727.
