I just bought this for 1K. 3.5 AWD. 174K miles. Zero rust Florida car. The story is a year ago she topped it off with the wrong fluid and has been doing it ever since. It bangs into 2nd every time. I drove it from Vero to W.P.B. 80 miles home down interstate 95. 70-85mph runs flawlessly the whole trip. So if anyone has experienced this, I'm interested. It has a small trans leak I will address, but I'm looking for some advice. 175K mileage so I'm concerned about replacing with new fluid. Also a/c not blowing cold. Any common problems? I used to own two auto business in upstate NY, so I'm not a newbie. Thought I'd rack your brains. I'll post my results.Thanks..
