Narrative:

Approaching dfw from the southwest with the first officer flying (autoplt engaged), we were cleared to 4000 ft on a 040 degree heading to intercept the runway 35C localizer. Confirming the field in sight, we were cleared for the visual and slowed to 210 KTS. Localizer was displayed in the FMA arm window, IAS 210 KIAS was selected, and the slats were extended. As we were about to intercept, the autoplt was having difficulty slowing and abruptly pitched up. The autoplt was disengaged and the appropriate pitch attitude re-established. By this time, we overshot the final. A left turn was initiated and a B757 was observed on final for runway 35R. The approach controller advised that we overshot the final, pointed out the traffic, directed a left turn to reintercept, and maintain altitude till established. I reported the traffic in sight. He directed another left turn. During this time, the TCASII issued a monitor vertical descent warning. Back on the localizer, the approach and landing were completed without incident.

Title: MD80 FLC OVERSHOOTS TURN TO FINAL AT DFW.

Narrative: APCHING DFW FROM THE SW WITH THE FO FLYING (AUTOPLT ENGAGED), WE WERE CLRED TO 4000 FT ON A 040 DEG HDG TO INTERCEPT THE RWY 35C LOC. CONFIRMING THE FIELD IN SIGHT, WE WERE CLRED FOR THE VISUAL AND SLOWED TO 210 KTS. LOC WAS DISPLAYED IN THE FMA ARM WINDOW, IAS 210 KIAS WAS SELECTED, AND THE SLATS WERE EXTENDED. AS WE WERE ABOUT TO INTERCEPT, THE AUTOPLT WAS HAVING DIFFICULTY SLOWING AND ABRUPTLY PITCHED UP. THE AUTOPLT WAS DISENGAGED AND THE APPROPRIATE PITCH ATTITUDE RE-ESTABLISHED. BY THIS TIME, WE OVERSHOT THE FINAL. A L TURN WAS INITIATED AND A B757 WAS OBSERVED ON FINAL FOR RWY 35R. THE APCH CTLR ADVISED THAT WE OVERSHOT THE FINAL, POINTED OUT THE TFC, DIRECTED A L TURN TO REINTERCEPT, AND MAINTAIN ALT TILL ESTABLISHED. I RPTED THE TFC IN SIGHT. HE DIRECTED ANOTHER L TURN. DURING THIS TIME, THE TCASII ISSUED A MONITOR VERT DSCNT WARNING. BACK ON THE LOC, THE APCH AND LNDG WERE COMPLETED WITHOUT INCIDENT.
