Runs very rough & shifts very hard

(1991 Dodge Dakota)
Hello a few weeks ago my engine light came on and then went back out. After this happened my truck started acting up. It idles very rough,and when driving it either shifts very hard or not at all. After I bring up the RPM' then let my foot off the gas it seems to shift. Can you help me?

Sounds like a vacuum leak maybe a vacuum line fell off or broke, see if you have a vacuum line that connects to the transmission.
