It maybe worth looking at getting it flushed to put your mind at rest. There are companies out there now that can offer this service using specialist dialysis type machines.
We used to do it at work with our cooling systems with a similar type of machine.

Some torque converters do still (apparently some Mercs) have a drain on them. But as you say, the easy way (with the correct kit) is to fill & drain the system via a cooler hose.
Having said I'd now pay someone to do it for me, I did a partial ATF replacement on my last car & changed about half of it. If I could find the will to post a picture I would ..... but I can't

Interesting, the only TC I have ever come across like that was in the Voith DIWA transmission. When you drained the gearbox, once empty there was an additional drain plug which you accessed through the drain hole to drain the TC. Also German technology.
On my Triumph Stag with a BW35 in it, I just did 3 oil changes over a month or so . But ATF for that is a lot cheaper than modern fluids like Dexron and other specialist types in modern boxes.

All autos will have a cooler. They actually say that changing the oil in an auto box can do more harm than good as draining the oil cause small depsits to end up where they shouldn't be, so I would only change it if it is burnt or a terrible colour. Most auto boxes need to have the sump taken off as that is the only way to drain the oil, as the oil is meant to last the life of the car, something I find extremely poor advice.
You will also need a filter and gasket set, plus the correct grade and amount of oil. You will also need the correct instructions on how to fill it up and check the level. It is a messy, smelly and expensive job, but if you have a day, and a way of getting the car off the ground, and level, then it is quite possible to do it yourself if you know one end of a spanner from the other.
You don't say why you feel the need for an oil cooler or an oil change? My advice, if it is running ok, leave well alone.
