transmition prob (AT)

yeah the Drive4 light (when having the problem) stays on no matter what I actually have the gear in. even when in Reverse or Park, it stays on. Thats how I can tell when it goes back to normal, when the lights are back to normal.

I guess this is something that needs to be fixed imediately? This really sucks cause I just saved up 200 for the cold air intake.:o I guess there goes that. I was hoping to spend money upgrading things, not fixing standard parts. An upgrade in a transmition would probably be at least a couple thousand, right?
