ENGINE IS COLD,THERE IS A BRIEF RATTLING AND THEN IT STOPS AFTER ABOUT 15 SECONDS.THE CAR IS NOW EXPERIENCING SHIFTING PROBLEMS..IS THIS A SPEED SENSOR PROBLEM..I'VE HEARD THE HARNES WIRES SOME ]TTIMES RUB AGAINST TIE RODS.
A SERVICE TRACTION SYSTEM WARNING MESSAGE CAME ON.DURING START UP,ONLY WHEN THE on 2002 Chevrolet Monte Carlo
Check All fluids esp. engine oil.You didn't say how many miles on car.Rattle on cold start sounds like bearing trouble.
what does engine oil have to do with traction control light?
Must have responded to the wrong question FIVE MONTHS AGO!! But after reading, engine rattle on cold start well maybe it does apply after all! Wow.
didn't mean to sound smart ---! I'm old school and figured anything possible with computer cars. just found this site and have a similar problem. not a warning message, but every few months the traction light comes on momentarily, with an odd (wrrrrr) sound while slowly leaving the driveway. the rt front bearing and hub were replaced in the past. could the sensor in it have anything to do with this if it goes bad?

It all good! The problem with your car is most likely an ABS wheel speed sensor,when the Antilock Brake System fails so does the Trac. control. Scanner will reveal which sensor is at falt.
Thanks. Merry Christmas to you as well

I still don't know. happened the other day. don't think a "warning" but it says "traction control active" I think. happens so fast and so rare I can't remember!!!
