So I bought an automatic 09 GS 2.4L @ 94k miles, and after putting a few hundred miles on it, the trans. started acting up. I'd be driving normally and the D on my gear display would disappear, and when I went to shift into something else, it wouldn't catch except for park. After letting it cool down and restarting it, it worked fine but would happen again after heating up. Since I didn't have money to take it to a Mitsu. dealership I just kept driving it since I was still able to get from point A-B. Then after about 700-1000 mi the problem just stopped, so I thought nothing of it. However the problem is back, but this time only reverse will catch after it driving some distance. Does anyone know what this could be caused by? The trans levels are good and the fluid seems pretty clean. I am taking it in tomorrow to get looked at, but any thoughts would be much appreciated.
