traction control

[mudderducker]

I took the truck to a local trail today, first mud adventure for the rig. I have a couple questions about TC. I pushed the TC button:

1. the traction control has no light or anything else to indicate it is on or off??
2. what are all those ridiculous clicks and whines it makes when it kicks on and off while the wheels are spinning?
3. is there a way to change the button to turn ON rather than OFF, where it is always off until engaged? it doesn't rain in Texas.
