Jaahn, I know I can be a pain in the A-se, but during my life, I have questioned many engineering situations, and also been able to make changes that have improved the situation. So it is, that I cannot just except the way transmission coolers are fitted to the diesel utes. Namely fitting the cooler in front of the intercooler. I cannot see how we are improving efficiency by taking heat from the transmission, and feeding it back into the inter-cooler and to a lesser degree the engine coolant radiator, not to mention the air con condenser. This setup which would have worked ideally in the days of petrol engine cars with no air con, has just been ported over to make do with todays diesels.
Australia can get hot, very hot, and in those conditions the outside temperature is doing everything wrong for engine efficiency, so I don't want to add to that. In cool conditions the cooler in the front would work. Fitting a cooler under the car is not my ideal, it is subject to water, flying stones and the chance of being caught up, but its the closest space available. Your comment about the fans cutting in when in traffic, is exactly my point, one is traveling so slow, there is no ram air to the front, but temperatures escalate, same as following a slow truck up a steep long incline, and that's when the fan assistance is required.
There is another spot that is possible, and the place I would prefer, but the length of hose or tubing would be in the order of 6 meters supply and return. I have attached a picture. I have emailed a company in the states, asking them if the 6R80 transmission can have this length of tubing, your comment is appreciated here if you can help.
Hmm perhaps I have also questioned the easy path and choosen the hard one myself But your choice and in this case perhaps the over hyped diesel twin cab utes are barely fit for the use the advertising people claim for them.
I have never owned one myself but in my life doing things engineering and working on vehicles, I have found that running at the very limit is never good and often means more work in the long run. A good general principle is to leave a generous margin, you never know when you might need it . Because all things, now more than ever, are built to a price, made to a price, and sold hard to buyers who are unable now to judge the true quality for various reasons.
I believe that wanted position is under the tray, in front of the wheel. Seems OK and suitable. As for the distance of the hoses, the standard answer is to go up a size in the diameter to reduce the fluid friction. Nothing hard about that solution and a bit extra capacity. You would need to clip the hoses regularly and keep them out of harms way. Some sensible proper fittings to stepup the diameter would be obtainable from a hydraulic hose supplier/fitter. As would the hoses. Low pressure rating only needed but do not use plastic hose, as that oil gets hot as you know.

Question, can anyone tell me the fluid pressure that the lines to an oil cooler is likely to have? if the return is going to the sump then the pressure would be near zero, but are there higher pressures involved.
