Here in Australia a lot of 4WDs and tow vehicles have additional transmission coolers fitted, and in a lot of cases the factory radiator-incorporated cooler is bypassed. Helps keep engine temps in check along with the transmission temps. I guess in a cold climate a radiator tranny cooler would allow the transmissionn fluid to get up to operating temp faster, but this is rarely an issue over here.
Buy a quality (large) transmission cooler, fit it correctly, maybe incorporate an adjustable thermo switch for the fan, and service the transmission regularly, and I reckon you'll see great results.
I don't know about the ZF, but a lot of tranny's don't like to be manually shifted (held in intermediate gears) and will quickly get hot if they are driven in this manner.
If a transmission cooler incorporates it's own thermo-controlled electric fan, it can be fitted almost anywhere and in any orientation. I feel this is a preferable option to sandwiching the cooler along with the radiator and AC condenser and expecting the engine fan to draw sufficient air through the whole shebang.
