1. A shiftable planetary transmission (1), comprising:
a planet carrier (2), a plurality of planet gears (3), a sun gear (4), and a ring gear (5), the sun gear (4) and the ring gear (5) meshed with the planet gears (3), the plurality of planet gears (3) rotatably arranged on planetary gear pins of the planet carrier (2),
wherein the planet carrier (2) comprises at least one connecting element (6) that is axially displaceable within the planet carrier (2), the at least one connecting element (6) separate from the planetary gear pins of the planet carrier (2),
wherein the at least one connecting element (6), on a first side of the planet carrier (2), is at least indirectly connected to an actuator (7) and, on a second side of the planet carrier (2), is at least indirectly connected to a first dog element (8),
wherein the first dog element (8) is displaceable, by an actuation of the actuator (7), between a first shift position and at least a second shift position due to an axial displacement of the at least one connecting element (6) in the planet carrier (2).
