Traction Control
Can someone explain just how the traction control works? ie,
What is the transmission doing to keep you from watching the rear end pass you by and when and how does it apply the power back to the wheels?

Basically I believe it is monitored by the same sensors as the ABS system uses. The computer monitors the wheel speed of the fronts and the rears and theoretically they should be turning at the same relative speed...when the rears are turning faster they are spinning and the computor takes several steps to correct it, starting with cutting back the throttle.

From Corvette.com:
Active Handling is an electronic symphony of Traction Control and antilock brakes working through microcomputers, accelerometers and stability sensors. While no system can overcome the laws of physics, Active Handling compares driver steering input with actual vehicle response. When necessary, it uses individual wheel brake application, the Traction Control System and available Magnetic Selective Ride Control to maximize the driver’s ability to maintain stability and stay on track.
Traction Control:
In the event of wheel spin, this standard feature automatically slows the spinning wheel down to regain traction and keep you moving.

....but by that point I'd say it's more active handling calling the shots!

My guess would be that if the rear wheels are moving faster than the front wheels and the yaw sensor and steering angle sensor indicate you are driving straight then brakes or engine cut-back is implemented to bring rear wheel speed in line with the front wheels

Thanks for the input. I knew the brakes played a large part but did not know what other factors kicked in. Was not sure about the engine cutting power but it makes sense considering the advanced systems on the vette.
