check engine light?

My Neon light came on & had it checked out. Had plug 1 & 2 misfiring. Had a Tracer once & drove it for over a year after the light came on & never had a minutes problem out of it...until I totalled it.

Did the shop reset the computer after doing the tranny work? If not that could be the problem. Once the computer is reset (good instructions given by other posters) see if the light comes back on. I wouldn't trust the OBD readout until the computer is reset. We have to reset ours (02 Ford van) every time the tiniest sensor is replaced.

We did drive the old 91 Ford van for over 5 years and 50,000 miles with the check engine light on. Hubby used to tease our son saying he needed to check the engine and make sure it was still there. We figured it was an exhaust recirculation canister that was the main cause when the thing fell off but with over 200,000 miles at the time and a couple dozen other little problems we just drove the van until it was ready to drop.

Codes can be useful...no are useful..but they are not definitive....they are the cars best guess as to what is wrong. For instance I have a 1986 Toyota 1-ton PU that was coding with a throttle sensor or computer problem....turns out it was a broken baffle in the catalytic convertor that was creating a backpressure the 'car' was diagnosing as a throttle sensor problem.....just something to consider in general about codes....

thats true, my 96 ford kept popping up a "idle cuircut failure" code, it was a hole in the exaust dropping pressure and making it idle funny.

On my wifes Car light was coming on before we bought it.The guy we bought it off of said he fixed it.Well all he did was shut it off.

The problem was some Valve that helps with take off,it studders a little bit.Most cars cost $30 to fix it.This one is $300.

Most part it runs just fine.So I'm not going to worry about it.
