A method and system for synchronizing downhole tractor and surface winch deployment includes inserting into a wellbore a tool string connected to a wireline, the tool string comprising a variable speed tractor, deploying the tractor, deploying the wireline from a winch; dynamically monitoring, by a device disposed downhole, a wireline tension as an indicator of synchronization of the tractor and winch, and adjusting, by the device, the tractor speed in response to a disparity in tension to match the winch speed.
