It’s at a second mechanic. He originally thought he could fix/rebuild it. Yesterday he called and said it would most likely be cheaper to get a used one to put in it because there’s very little salvageable from the one in it. The issue had been it would not stay in 2wd. He said the prior owner had the wrong fluid in it and had rigged something to keep it going. I’m not sure what all needs replaced in it but i know the chain, the gears and the vacuum hoses were completely shot.
