played in the mud a little and now will only shift to 2nd while the gas is applied.let up off the gas and will shift to drive but the minute i press down on the gas again it goes right to 2nd.codes were ran and only one for the tranny was the coast clutch soleniod.the others are p1131,p0161,p0156 and p0135,all have something to do with the o2 sensors.that wouldnt stop it from shifting would it?

when driving down the road it feels like it wants to change gears but it dont.when doing 45mph the tac is about 3000rpm and when I step on the gas alittle more it feels like the tq converter unlocks then locks again?the rpm will jump up about 200rpm more then drop down when it feels like it unlocks.
