Here is my quick and dirty run down.
Without a trans cooler in the radiator you will need a heavy duty auxiliary cooler. The key is keeping that aux cooler cool either with the engine fan or a dedicated electric fan.
IF you have a decent shroud, engine fan and good airflow through the radiator (i.e. no obstructions in front of the grille), your best option is to mount the aux cooler to the front of the radiator using plastic tie straps (available at most parts stores) or fabricating brackets to the radiator.
This is preferable IF you feel your current cooling setup adequately cools the engine in all phases of travel (city, highway, trail).
If ALL the aforementioned conditions do not apply, I would suggest going with option B; mounting in an alternative location with an electric fan.
The two places that many folks mount their trans coolers (for a multitude of reasons including space or airflow issues) are under the passenger floor board or on the front side of the driver side wheel well inside the engine bay. The key to these two locations is ensuring adequate clearance for optimal flow. Both locations have drawbacks including ambient air temperature and environmental contamination. If you are not willing to do some modification to the core support to allow air to flow through the grille to the cooler on the wheel well, I would mount under the floor board.
Mounting under the floor board can be accomplished with a few angle brackets attached to the back of the rocker and the outboard side of the frame. When mounting in this location take notice of your exhaust routing as it is possible to draw how air from that area and insulation or air dams may be necessary.
Consider using a temp switch to actuate the fan. You do not want it on at initial warm up as you will need to allow the trans to reach operating temperature. You can mount a temp switch in the pan or at the output from the converter to be conservative since it is the hottest temp.
The ideal transmission temperature is 150-180 degrees. You never want to exceed 220.
