No I have not changed the fluid.
I got my t-belt, t-belt tensioners, and waterpump professionally replaced recently to see if the faint noise would go away but it did not and they could not hear the noise I was talking about since it was so faint inside of the Honda Shop. A few weeks later the noise becomes very noticeable and I am not the only one to notice it when the hood is even down!
What are the signs of a trany kicking the bucket? A noise like this?
