You may be thinking of Dick Tidrow, who was at least a serviceable reliever for the Evil Empire in the mid-70s.
But those deals have nothing on the incestuous relationship between the Yankees and the Kansas City Athletics in the late 50s. Notables who went from KC to NY: Ralph Terry, Hector Lopez, Roger Maris, Art Ditmer, Clete Boyer, Bob Cerv and Harry Simpson, most acquired for castoffs. Cerv and Terry were originally signed by the Yankees, dealt to KC for a couple of years and then reacquired. The attached article has a more complete list, but the bottom line was that the KC Athletics of those years were serving as a virtual farm club for the Yankees. It notes that of the players on the 1961 Yankees (one of the best teams of all time) 10 had played with the Athletics.
