i posted this over in the talk forum and i'm not getting much of a response. i'll try it over here. forgive my impatience. i'm looking at a 90' 5-spd trooper over in georgia. i'm visiting my folks this weekend, who happen to live fairly close to this trooper. everything looks good except the owner says the transmission makes a constant noise in 5th gear (only 5th). he said it started, roughly, a year ago. i did some searching and it sounds like he has put gear oil in his transmission instead of regular oil. is this an accurate diagnosis or could it possibly be the clutch going out.

should i buy it or keep looking?

thanks for the help
