Help! RARE noise coming from transmission
Hi guys, hoping to get some opinions on this. I am kind of in panic mode at the moment. I own a BABIED 2004 GTO 6 speed with 75k on the clock. A noise recently started emitting from the tranny when in gear which really has me confused. It happens when in all gears, but 4th is significantly louder than the others. It's also there in neutral but much more faint. And only when the clutch is out. Now what is strange and also relieving is that it is NOT a grinding, whining, growling or clunking noise. In fact I went through dozens of youtube examples of bad transmission noises and mine does not resemble any of them. The most accurate way I can describe it is like a wheel on a skateboard spinning. It does not sound like something is broken, but rather I am hearing a normal function which shouldn't be so loud. Car shifts likes butter and drives like new. I rarely beat on my GTO and have always taken good care of it and been conscious of my driving habits. At 75k miles there should be absolutely no major issues. I am going to swap my tranny fluid very soon and pray that solves the problem. But in the meantime I am hoping someone else has experience with this and can shed some light and give me peace of mind. Thanks.
