Ok! So I am going to give as much detail as possible here.
Traction/ABS - This problem started with traction kicking on when I was on dry roads. Now, Service Traction System light comes on in conjunction with the ABS light. I read in another post to check wiring & then replace wheel sensor/bearing assembly. I plan to give that a try this weekend, but might be useful for any other advice on this as well.
Security Light - I have heard horror stories about Security Lights coming on (mostly from Cadillac's) and not being able to start your car. Ok, mine is a little bit different. The security light does not come on when turning the car on or anytime near starting it - most generally it will pop on while I am driving. No specific speed, no specific time. I never know when it will come on. If I shut the car off, I have no problem with starting it immediately back up. I have never tried to wait and see, but when I start immediately, the light does not come on.
Rough Idling - I have had problems with the temperature gauge inside the car (dash board) not working. Not your normal not working, but works when the temperatur outside is 60+ degrees, and not if under. Through some advice of a friend, I replaced the temperature sensor (which is not as easy as everyone here had said), but I am still having the problem, but as long as I am careful and not turn the heat on too high or too quickly in the morning's - I have no problem. OK, so to the rough idling - Primarily when I have the heat on.
All at the same time - I still owe $9k on the thing and have had enough problems that I would NEVER recommend the car to anyone. AND this is coming from an avid Chevy fan. I have never owned anything other than a Chevy, but I am begining to wonder what Chevy has been doing lately ...

Re: Traction/ABS, Security Light & Rough Idling
YOUR CAR HAS AN ABS SENSOR ON EACH WHEEL! YOU SHOULD HAVE THE CODE READ SO U KNOW WHERE TO START.MAY SAVE YOURSELF SOME MONEY.ROUGH IDLE W/HEAT ON.CHECK THE VACUUM LINES GOING THROUGH THE FIREWALL.WHEN U HAVE THE HEATER ON THE VENTS RUN OFF ENGINE VACUUM.LOW ENGINE VACUUM=ROUGH IDLE.G.M. NEEDS A 100K WARRANTY.THERE STUFF KEEPS THE AUTOMOTIVE REPAIR SHOPS VERY BUSY.
I have a problem with clunking in the steering column well I found out what the problem is it's the intermediate shaft that has to be replaced cost 129.00 parts 169.00 labor it seems a lot o GM cars have this problem starting with 2001 cars right up until 2008 if anyone want's a list please post and I will let you know what cars are on the list
a 6ya expert can help you resolve that issue over the phone in a minute or two.

The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control

How this system works:
Traction control uses wheel speed sensors to detect when one or more of the car's wheels lose grip and traction. When the system registers a loss of traction in one or more of the wheels, a computer will limit power to the wheels that are still in solid contact with the road to prevent a skid.
Common reasons for this to happen:
ABS is malfunctioning: Traction control and ABS (anti-lock braking system) often share the same control module and internal self-diagnostics system. As a result, sometimes an issue in the ABS can trigger the traction control light. If this is the case, then both the ABS and Traction Control lights will be on.
Broken wheel speed sensors: Wheel speed sensors are usually in the wheel bearing assembly, and determine the rate at which each wheel is moving. The sensors relay that information to the traction control module, which determines whether or not power needs to be shifted. Wheel speed sensors can get dirty or damaged and stop working, which prohibits the traction control module from knowing when to enable the system.Traction control module is faulty: The traction control module - which, again, is often shared with the ABS - can malfunction and break altogether, causing the system to stop working.
What to expect:
A top-rated mobile mechanic will come to your home or office to determine the source and cause of the traction control issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.
How important is this service?
It's important to have the traction control issue investigated as soon as possible, as adverse driving conditions can arise at any time. While your car is unlikely to incur further damage from a faulty traction control system, it won't be safe to drive in rain, snow, sleet, or other inclement weather, or even possibly through pools of water on the road. Furthermore, the issue that is causing the traction control light to illuminate could also be impacting the ABS.

I would think you have more than one problem. The ABS and traction lights mean those systems are disabled and they work together. So if one is out the other will be too. You probably need to have the systems checked for trouble codes.
As for the no start, if it is a no crank situation you would need to know if the starter has battery power when the key is in the start position. Could be a security problem, the neutral safety switch, or several other possible causes.
if the abs light comes on then there is a code in the abs module to direct you to the problem. find out the code first, then start digging to find the source of the problem. as intermittent as it is it does sound like an internal module problem,but it will set a code in memory if it is the case.
Had the same problem with my 2002 Lincoln LS, it was a bad wheel speed sensor. The right front wheel bearing had some play in it, so I had the hub assembly replaced. The hub assembly comes with a new wheel speed sensor attached. After I replaced the hub assmbly with sensor, the ABS and Traction Control lights went off. No problem since!
It is possible that one of the two front sensors or the wire to the sensors was inadvertently damaged when the transmission was replaced since the subframe needs to be removed in order to do the job. It is also possible that it is a fluke as ABS problems are normal for these vehicles. Check to make sure the front wheel speed sensors are still plugged in and the wiring around the connectors is in tacked.
The best thing to do is have the ABS module scanned to retrieve the trouble code(s). This will at least give you a direction to go in and start searching.
The traction control uses the ABS system to work. If there is a problem with the ABS than the traction control will automatically be turned off.
had my 2000 chev impala 3.8 liter ,traction control llight and abs light both go on the reset it and go right back on .so i replaced both sides of the bearing hub assembly this is connected the senser,so far so good.replaced it dec 21 2009 about 3 hours ago. because the assembly came appart when took off.
I assume tht is traction control. Check fuses ,eeven abs fuses ,traction control is part of abs. If fuses ok will need scan tool to find cause of lite going on. Most common are abs sensors and broken abs wires. And if abs tone ring is part of axle shaft some rock may have damaged teeth of ring .
The traction control system uses the abs wheel sensors to detect wheel speed if the abs light is on the entire abs system will disable giving you regular braking but it will also stop feeding info to the traction control
