04 dakota stuck in 3ed someone help please
So I have an 04 dakota 4.7L 4x4 quad cab. Heres what happened. I was out of town, started it up. Sounded good. Then when i stuck it in drive ( automatic tranny.) It harded shifted pretty good. 6 months later im still stuck in 3ed gear. I have reverse, neutral, and park just fine. But drive feels like 3ed. If i pop it down into 1st you get a what feels like second. Pop it into second and nothing happens. When on the interstate you only get about 55 and 3000 rpms. Anybody know whats going on here? I really cant afford to buy the wrong part and we have no transsmision techs close by.
