Try disconnecting the battery for about 10 minutes to reset the code Went to Autozone to see if I replaced the wrong part. They said I had to wait "a while" till the change was recognized. That the computer used some type of formula of engine starts, miles, and gears shifted through before it would turn it off. It has been 3 days, about 8-12 engine starts and about 30 miles.
