    Test the TCC Solenoid to see if it has failed electrically. Replace it using this inexpensive procedure if it has.

    Re: P0741 and state inspection

    I would like to amend my initial post. My car started throwing code P0741 about 4 years and 40,000 miles ago. It would only set if I was in OD and went over 41 mph. The code is now setting if I drive in 3rd. I am getting ready to go through inspection and was going thru my ritual.

    So at some point if you do not get your trans repaired the code will begin setting in 3rd which will make my initial post invalid. Sorry for that folks I didn't know

    will this work on a 2003 DeVille?

You will fail inspection if your car has any PCM codes. The way to combat this without having your car repaired (very expensive) is as follows. First, through the DIC, clear the codes. Do not go to inspection at this time as your emissions system will not be able to be read by the inspectors computer and you will fail. Drive the car for a week or two only in third gear. The P0741 only sets if yoiu are in overdrive and get above 41 mph. After your week or so of driving your systems will be "ready". Go back to inspection, and you should be golden. I checked for the code after every drive and it never appeared.
