have an 89 LX with 105k miles and an AOD tranny. took out for gas when i put car in park, it made wierd noise and car shut off. would not restart in park, only in neutral. can not put shifter in park, reverse, or 1 with out car shutting off. Thought maybe filter was clogged, but it was clean as was the pan. fluid was like a dark grey color. Wanted to know if i needed a new tranny or if it was an easy fix? also will any other transmissions fit such as out of a lincoln or grand marquis?
