TRANSMISSION SYSTEM FOR HYBRID ELECTRIC VEHICLE A transmission system (TM) for a hybrid electric vehicle (HV) includes a planetary gear mechanism (10), a gear (12), a parking lock mechanism (80), and a resistance imposing device (100). A parking meshing member of the parking lock mechanism (80) acts so as to switch between a first state where a claw (87a) is in mesh with a parking gear (86) and a second state where the claw (87a) is out of mesh with the parking gear (86). The resistance imposing device (100) includes a resistance imposing member (102) configured to impose a rotational resistance on the parking gear (86) or a third rotating element (13) of the planetary gear (10) by coming in contact with the parking gear (86) or the third rotating element (13). The resistance imposing device (100) is configured to operate the resistance imposing member(102) such that a larger rotational resistance is imposed on the third rotating element (13) in the first state than in the second state.
