Aircraft
We were cleared to descend via the ZZZZZ 4 Arrival into ZZZ. We had the autopilot on; we were slowed to 220 knots over ZZZZZ per the arrival. We saw a pitch trim annunciator on the PFD. The trim wheel was at the full nose down position. We could not move it any more forward. The aircraft wanted to pitch up when the autopilot was turned off. Approach assigned us 190 knots. Once the aircraft was slowed down; we could move the trim wheel a bit back; then a bit forward. Approach then assigned us 170 knots. Once the aircraft was at 170 knots; then trim seemed to work normally. We ran the jammed elevator trim (in cruise position) QRH. We decided to land with flaps 15. We than ran the flap fail approach QRC; and the flap fail landing QRC. The landing was standard. We did not declare the emergency because we had the aircraft well under control. We checked the runway length and ZZZ had enough runway. I'm still not sure why we had a full forward trim at 220 KIAS.
