Hello all! This is my first post but I'm on the altima.net board all the time. My gf has a 90 maxima so I was wondering if I could get some help. I'm hearing this clicking sound coming from the shifter. She has an 90 maxima auto. It runs great and shifts smooth. Its just this clicking sound coming from the gear shifter. I thought it might be the fuild but its full. I was just hoping if someone else ever had an issue like this before. I tried searching but no luck on relevant matches.

and mods...please let this one slide so I can get some help!
