You may not be able to get all of the tranny fluid out, but don't keep adding flush as it will start to do damage as the concentration of it will increase. After you replace the radiator or install a cooler, bring it to temperature and drain the radiator. Refill with water, bring it to operating temperature again and drain it. You want to get out the fluid that is stopped by the thermostat when it is closed. Another option is pull the thermostat and then operating temperature is not required.
I find that U-haul dealer can put in a cooler for about the cost of just buying one. The radiator replacement would be the smarter way to go.
