Short in system and shifting problems

My truck was skipping and obd said plugs were misfiring. But on further steady I had one of my wires back on the driver side shorted out on a stud in the firewall I guess it either arched or was rubbing on the thread but the wire was melted to the stud. So I taped the wire up and the skipping stopped no more misfire codes and I also previously had a shifting problem I replaced both sensors but when I went to go on the highway and kicked it down it started not shifting again so I just replaced both sensors again no change so now this is the list of scan codes obd2 diagnostic scan codes on 2001 dodge dakota p0152, p1765, p0031, p0753, p0051, p0132 any feedback would be greatly appreciated.
