I have an SC4 and occassionally when I accelerate (in either normal or ect mode) there's a grinding sound that emits from what sounds like the transmission (or at least near it). This happens with and without steering the car and only when accelerating. Does anyone know what I'm talking about? I'm almost afraid to drive my car now for fear of damaging it.

 

Just looking at some old posts. Hey Rich, did you ever solve this problem?
