It simply means that the engine computer has noticed that the transmission computer has a dtc in it. This causes the Pcm (engine computer) to turn the check engine light on. You will need to have the TCM (trans computer) checked for codes to know what to diagnose.
General automatic transmission fault. It could be a sticky internal sensor. A transmission shop could read the actual fault from the transmission.
2003 Chevy Trailblazer service engine soon light?
Same happened to me. It would come on, then a few days later it would go off. Took it to Jiffy Lube for an oil change, and they came in and told me that the connector to the light was loose. So they pluged it back in. And its fine now. I believe Auto Zone does a free diagnostic test. You could do that to see if anything is wrong first. Hope that helps

My car seems to smoke every time I start it, but then it goes away. Do you think I need car repair?
Yes, this would be a sign to take it to a vehicle service place. If anything abnormal happens with your motor vehicle, or if the check engine light comes on, it's time to take it in for a checkup.
More then likely the smoke coming out every time you start the car is from your car burning oil. This could be just a simple problem that will not require much attention or it could be something major. I would take your car to your local mechanic. Most will check it out and give you a free quote on how much it will cost to repair. At least if you take it in you will find out what the problem is.

2001 Chevy Impala check engine light stays on?
Most likely you have a inoperative oxygen exhaust senser .Depending on your car,you have two for sure,up stream and down stream .Usually one is located on the right exhaust comming down from the exhaust manifold and another past the catalistic converter. You might have another one located on the left exhaust comming down off the exhaust manifold.These are expensive to replace "BY GUESSING" which one. No way to tell which one it is,unless you are advanced auto home repair,and have a manual for your car ..(HAYNES, ADVANCED AUTO STORES) and understand how to do it the inexpensive way. I purchased a CODE READ OUT module, and for each car i have owned,i have purchased a HAYNES repair manual for it. HAve a friend that has some good knowledge to guide you along.Once you spend the money for the code read out,over time it will pay for its self by you NOT having to take your car into the shop to have it hooked up to a computer to find the trouble code.That alone is usually $75.00. The oxygen sensors can cost any where from 47.00 to 90.00.each. If i have burdened you with this info,settle back and relax,this is not a difficult task.The trouble code finder can cost you 130.00 for a excellent one that you can operate with no problem.Just follow instructions that come with the trouble code finder and look through your repair manual. You not only save money also you are learning about your car and many ways to keep it in excellent operating condition. Take your time and enjoy.

Service vehicle light is on 2001 Pontiac grand am?
I have had this happen many times, and the culprit is usually a fuel cap that has not been put on correctly. Check your fuel cap, remove it, and re-install correctly. It will take a while for the light to go off again (sometimes up to half a tank of gas), but it should be out by the time you need to fill up again. I have also had one instance where I filled up at a non-chain gas station, and my light went on. It stayed on until I ran another complete tank through, and the only answer I have is that it was crappy gas. I don't know much about cars, but I understand that the fuel system is pressurized, and when your cap isn't on correctly, your car's computer recognizes that there is something wrong with the system pressure, which turns on the light. Hope this helps
