Dumb question no 2 million and three

[Lippyp]

I need to take my radiator out so I can sort out my electric fan setup properly. Its an auto with the in rad cooler. My question is do I just undo the tranny cooler lines and plug them with a bolt or something whilst the rad is out? Also when I refiot it do I need to refill the cooler somehow or just run the engine and top up the transmission the usual way? Will it refill the cooler if I do that or is it likely to airlock and cause me problems later on? I can't take it out for a drive as its currently not road legal here.

I am replacing the nasty bodged on small four bladed electric fan that only covers half the rad with a fabricated aluminium shroud and a larger 8 curved bladed two speed fan (from a Volvo 850 T5 actually!) and an adjustable electronic thermostatic controller in the bottom hose to operate it rather than the curreent manual switch in the cab that requires me to keep a constant eye on the temp gauaghe. To be fair its never come close to overheating but I'd like a bit of extra assurance and automatic operation.
