When at a steady speed in overdrive the car makes a low pitched sound. If given gas the sound goes away.

Good afternoon,

This sounds like it could be a torque converter making the noise.

How long since you changed the fluid and filter in the transmission?

I would start there.

Fluid and filter were changed at 200xxx. Is it possible to just be the noise the car makes? I haven't owned it long so I'm not sure what a normal sound would be from it.

No. The noise is not normal.

I would still have the fluid changed.
