Do I need a special ferule for A TM reshaft?
The ferrule inside diameter should match the outside diameter of the shaft AND the outside diameter of the ferrule should be larger (to allow for turning down) or match the outside diameter of the top of the hosel.. In addition some hosels have a larger inside diameter at the top of the hosel requiring an inset ferrule. Once the head has been removed you will have your answer. Within a specific manufacturer's line there is rarely any standardization.
