Narrative:

Location: 10 NM north of dfw. On arrival we were vectored at 4000 ft across the approach to runways 17 for a visual to runway 18R. As we were cleared for a visual to runway 18R and descending out of 4000 ft TCASII issued a traffic warning TA not RA for an aircraft going to runway 17C crossing behind us with a vertical separation 800 ft, 2-3 mi behind us. Dfw approach called our position to the other aircraft. On landing I called dfw approach and the controller felt no traffic conflict existed.
