Sometimes when I start-up my 2007 Saturn ION, I hear this weird noise. I'm not entirely sure how to describe it. The car starts normally at first then it sounds like something in the engine or transmission starts to vibrate or it sounds like something is spinning really fast. It does it for like 3-5 seconds then stops. Is any of this making any sense, its a really strange noise and hard to describe.
I have also noticed that when idling at stoplights my transmission sounds like it has something rattling in it. I was reading my owner's manual and it recommends transmission fluid to be replaced at 50,000 miles and I am now at almost 80000 and haven't done this. Should I have had the transmission fluid replaced at 50k? Could this have caused some damage to my transmission? When accelerating my transmission also has a very slight whine. My right leg rests against the plastic area below the shifter (automatic transmission) and I can a strong vibration when accelerating.
I hope some of this makes sense and you can give me an idea of what is wrong.
