I'm no expert here but when you changed your Trans did you reset the pcm by unhooking you neg battery cable. Tun your headlight switch on wait 15 min turn off headlights rebook up battery cable. Start it my run rough till it relearned Then see if the p codes gone and it runs and shifts.

Gonna say faulty tps sensor as well. When this happened to my 93 dodge shadow ES I thought too it was trans but a little reach. $50 tps fixed it
