Default Traction Control

Just a quick question....... when the traction control is on and the computer picks up any wheelspin is this going to work like a anti-lock brake system? Or is going to pull a bunch of timing out to try to stop the wheel spin that way?

From PT

I have a 2003 GT (HO) with 5k miles. There seems to be some debate about how the performance of traction control (TC) compares to a limited-slip differential (LSD). I understand how both work, but am curious. Thank you for any feedback that you can provide. - Hal, from Iowa.

LSD - A differential fitted with a mechanism that limits the speed and torque differences between its two outputs. Limited slip ensures that some torque is always distributed to both wheels, even when one is on very slippery pavement.

TC - An enhancement of an existing ABS system that prevents wheel spin while accelerating on wet or slick surfaces. It uses the same wheel speed sensors to monitor wheel speed during acceleration, but requires some additional control solenoids and a pump to apply braking pressure to control wheel spin. The traction control system brakes the drive wheel that's starting to spin to shift torque to the opposite drive wheel that still has traction. Most traction control systems only operate at speeds up to about 30 mph (PT - 35mph). Additional control strategies that some traction control systems use to limit wheel spin include reducing the throttle opening, upshifting the transmission, retarding spark timing and deactivating fuel injectors.

Not the same on a manual tranny car. Can tell you I burned a clutch due to being an idiot and leaving TCS on for a run down a 1/4 mile track. One run, one dead clutch....

The Chrysler traction control uses the brakes to stop the spinning wheel. In extreme cases it will tell the engine to reduce power but only in extreme, prolonged events.
Chrome nut.. How did you kill the clutch? I can't see how. I run mine out constantly and have never had a problem with my 06 GT with Stage 1. Did you miss a shift? I know if you accidently go from 3 to 2nd at full speed that will smoke a clutch. Only other thing I can think of is if you where riding the clutch?

During the little snow I drove in last year with the PT, I played with the traction control (and ABS) quite a bit. It worked as advertised though not without some disconcerting clunky noises. Though not impressed; it was probably as good or better than a limited slip diff...

Yeah, both ABS and TRAC clack like mad.
When it first engaged, scared hell out of me...
