Narrative:

[During] preflight; stab trim channel [was] inoperative and reset by maintenance control before departure. After takeoff; in the climb; it failed again and would not reconnect. Checked with maintenance and dispatch if they would like us to continue or return and they stated to continue. Just after that; [we] received a stab fault message and uncommanded pitch changes and audio warning of the same with the autopilot on and off. Notified ATC we wanted to return to [departure airport]. Notified [company] we were returning. Did not declare an emergency and when ATC wanted us to join the arrival I asked to go direct to the airport. They granted the request and when we arrived crash rescue was waiting and we did an overweight landing; 77;000 pounds; 100 FPM descent and 149 KTS. Brakes went up to 3 when we were in the gate. Made write up and notified dispatch and maintenance.
