The check engine light works when the car is turned on before starting it and when I run a ecu code check. The shift light works right before the car is started and also if I redline it in neutral it comes on just before redline. I have eliminated the fact that either light is burned out.
I titled the post that way because 99% of the time when someone says their shift light doesn't work they dont realize that if their check engine light is on the shift light doesn't function. I have no CEL and a random shift light. Also very decreased mpg.
