There's more than one way to do this, but I can give you a couple tips to make this easier:
First of all, remove the passenger side plastic fender well, it's not that hard and it will give you easy access to the tranny cooler lines. You can't really access the cooler lines any other way (especially at the bottom of the radiator).
Second, if your installing the thermal bypass you need to identify which cooler line is coming from the tranny. The easiest way is to disconnect the two lines at the front of the truck and rubberband a plastic bag on the end of each line, and start the engine for a few seconds. The bag with the tranny fluid in it will be the line coming from the tranny. You don't want to make the mistake of hooking the return line to the inlet of the thermal bypass.
BTW there was a service manager of a Texas Hummer dealership who posted regularly on the Hummer X forums who stated he saw as many as 3 H2's per month come in with a ruptured internal radiator tranny cooler.
