I'll assume you are referring to the Tiptronic cooler as the manuals did not have a trans cooler. First think you need to determine is if it is the cooler itself, or the lines, or the control valve that is actually leaking. None of these are particularly hard to swap out, but you need to be comfortable working in very tight spaces as there is not much room around any of them.

Once the repairs are done, you will need to top off the cooling system and get the air pockets out.

I have not done this swap because I don't think it happens that often. But I remember looking at it while I was under the car and it looks straight forward enough. Be sure to get all the gaskets and orings you need.

As for bleeding cooling system, get an Air Lift. You are done in 5 minutes. No bleeding.

That 997 is hard to bleed normally so AIRLIFT is the ticket.

No. The Airlift system is not designed to extract coolant, only air. You do a gravity drain, then evacuate the system before pulling the premixed coolant and distilled water (50/50 mix) into the system. One shot refill in about 5 min., no follow up bleeding required. This is why shops used this system, no come backs.

You empty your cooling system. All of it.
You use the Airlift to create vacuum in the system.
Then you let the vacuum suck in the new coolant to fill it up into all the air pockets.
No bleeding is required cause no pockets exist.
