Narrative:
Autopilot pitch control was acting erratically. We turned autopilot off and tried control with the right side computer. There was no change. When we attempted to turn off autopilot to hand fly; the trim wheel stuck in the full forward position. We were able to over-ride and hold force against trim wheel until reaching a lower altitude on approach into our divert airport. We were able to land without further complication.
