On my Trucool Max I installed in 2011, just for date reference in case there has been a change, the cooler is 3/8 inverted flair. I went to a well stocked hydraulic shop that catered to race cars and the guy was able to accomplish what I needed in two fittings. 3/8 Inverted flair to AN adapter and AN to 1/2" barbed hose. A few more convenience fittings of a 90 in AN and a taped coupling to insert my thermostat that turns on the Trans cooler fan. I was concerned about the restriction of the stacked fittings since I was getting a new transmission installed at the same time by John Wood. John said 3/8 fittings would be fine but to maintain the 1/2" hoses. So that's what it's been for the last 7 years.
