I think the problem you face is when both wheels spin the same speed, which from a stop, that's easy to achieve, TC won't kick right in or at all. I notice that often if I'm on pavement with a layer of sand on it. you get on it from a stop, it will spin for quite some time, gotta just let off the gas. Now if you're rolling already and one wheel slips, that's the TC's bread and butter. It will adjust speed on the faster wheel until they both "get grip" or at least the computer thinks you have grip based on the similar speed of both wheels.
The TC is probably not well designed for icy conditions. That's the case with a lot of FWD cars. Better tires, and some feather on the pedal is probably your only way to solve when you take off in a slippery condition.
