Lear,
I just checked the throttle hold on a stock Trex450 and it works fine. This is all about channel and axis assignments. I guess my suggestion for you at this point is to work backwards, eliminate all the axis' that already work fine, and experiment with those that don't work. Example: look at the top most line in the transmitter edit, what axis does yours show? Mine is axis 6 and it controls on of the basic 5 control surfaces, that means the Throttle hold on your TC9CAP isn't on Axis 6. I'd just keep going through each channel and after you exclude the 5 basic controls, work with what's left. I don't know how else I can help with this, since I don't have a TC9CAP.
Good luck
Scott H
Lear, have you tried to set your radio like the FAQ:

I imagine that one of these of switches is your throttle hold, spend a few minutes here to get some experience and you should be able to set any axis you need.
