A tieback connector will tieback an upper string of casing to a lower string of casing at the wellhead of a subsea well. The tieback connector has a lower tieback member than latches into the wellhead. A lower landing shoulder is located in the wellhead. When reconnecting, an upper tieback member is lowered with the upper casing string. A landing sleeve carried by the upper tieback member has an upper landing shoulder for engaging the lower landing shoulder. The upper tieback member will move between an upper and a lower position relative to the landing sleeve. The landing sleeve first contacts the lower landing shoulder before the upper tieback member threads contact the lower tieback member threads. Then, the upper tieback member will move down to engage the threads.
