Its not a IDM problem, if you light doesnt work, it should come on when you press the button, if no you need to probably replace the button on the shifter. i would have it scanned for codes, it may have some tranny codes. I would NOT spend any money on the IDM.

No its not kicking overdrive off by itself, you probably have a faulty button b/c yours wont light up when you press the button, and the light and button are an assembly, and if the light doesnt come on when you press the button, it wont flash when there is a transmission fault, i would reccomment replacing the button/light assembly on the shifter, and seeing if the light will work then. If it does work after you replace it, if you do have transmission problems it will flash. Sorry this is kinda confusing, but i hope it helps.
