Well, just go to the app drawer on your DHD (desire HD) and look for the program "wifi hotspot"
it should come standardly installed on your DHD. Start this thing up and press OK. Then enter the name you want for your Hotspot, and specify a WPA key to your choosing.
Then tick the box on top, wait a few seconds until it's started and after that, you can just search for wireless networks on your Transformer and you will find your "desire hd portable hotspot". Login with the WPA key you have chosen and enjoy the world wide web
