Still no resolved issue for Jeep, any suggestions?

I mentioned that my 04' Wrangler with automatic transmission was having a problem upshifting, especially uphill. As I approach a hill, maybe around 60rpm's, I'll start to give it more and morepedal pressure but the RPM's will not budge until pedal is almost at floor and all of a sudden will jump which seems pretty harsh on the jeep. I had another problem with downshifting recently and had the tps and map sensors replaced which helped that issue but this lack of upshift still remains. Could this be another electrical/computer problem? Any suggestions? Thanks!!
