I have a 1987 Nissan Pathfinder I have had it for about a year now. I never had an issue with my Pathy till today. I got home today and as I was reversing into my space either my tranny or transfer case started making a grinding popping noise. but only in reverse. Can anyone tell me if this has happened to you? And what you did to fix it? I have a 5 Speed tranny, 4 Cyl Z24 motor.
