Synthetic engine oil is good but (for the cooling aspect) synthetic trans fluid is essential IMO, for dissipating heat build-up through an auxiliary trans cooler.
Few chemicals will dissipate heat better than water. It is important for your trans fluid to pass through your radiator to remove as much heat as possible (unless you have a very big external trans cooler or multiple trans coolers). The addition of an auxiliary trans cooler will assist in removing that heat and keeping from having some of that heat from being dumped into the radiator. However, when using synthetic trans fluid with an auxiliary cooler, it makes the auxiliary cooler 100% more effective because synthetic fluids release heat at a far faster rate then petroleum fluids.
You can also get synthetic power steering fluid. When towing (or carrying any heavy load), there is more stress on your power steering also. I also switched to Synth P/S fluid.
