Block drain not necessary
Before replacing radiator blow hose water up through the lower hose until
clear, drain fill, drain, install radiator, fill with clear water run untill hot (thermostat open) drain repeat until clear.
Of course the motor has no rusty colored water to begin with?
If so there may be head erosion problems.
Yes check ATF level and oil cooler
