Cagney & Lacey (1982)

Chris Cagney and Mary Beth Lacey are NYPD detectives with opposite temperaments, one tough and guarded, the other more open and sensitive, and the show lets them argue about the job, the squad and their lives as much as the case in front of them. That makes it feel closer to a workplace drama than a puzzle show, and the partnership is the thing that holds every episode together. It is very much a 1980s series in look and pace, but the way two women back each other up while disagreeing still lands.
