Not going into overdrive

Replaced water pump, car would run great cold, once warm acts like its struggling to get into overdrive, it jerks back and forth? Stays in second gear, Shifts into all other gears fine. Had code read said camshaft sensor so replaced it, still doing the same, had code read again showing cam and crank sensor bank 1, replaced crank sensor still doing the same thing when it get warm. What else could it be? Also, ran codes on transmission itself, nothing came up.
