A shifting tool for use with an isolation valve. The shifting tool may include a mandrel and a first shifting assembly positioned about the mandrel. The first shifting assembly may include a shifting member engageable with a profile of the isolation valve to shift the isolation valve into at least one of an open position or a closed position, a sleeve engageable with the shifting member to prevent disengagement between the shifting member and the isolation valve, and a detent mechanism engageable with the shifting member to prevent disengagement between the sleeve and the shifting member. The detent mechanism may engage with the shifting member when the shifting tool initially engages with an isolation valve and relative movement of the shifting tool with respect to the isolation valve may disengage the detent mechanism from the shifting member when the detent mechanism reaches predetermined location within isolation valve.
