Hi,
I have 69 Polara with 383 cui + 727 transmission. Recently, I noticed the noise coming from the transmission when neutral is selected. The noise is present only on neutral, no other gears including parking position. It sounds like some rotating parts rubbing against each other. I have tried to make a short video, but its quite hard to notice, its mostly noticeable at the end of video.
