Abstract: A transmission assembly for converting a garage door operator (GDO) from a ceiling mounted configuration to a jackshaft configuration may include an output coupler for operably coupling a drive tube rotatable to alternately open and close a sectional door, a pinion assembly operably coupled to the output coupler via a flexible coupling member, a releasable coupling assembly, a handle, and a cam operated engagement assembly. The releasable coupling assembly may be operably coupled to a motor output shaft of a GDO motor. The releasable coupling assembly may have an engaged state in which rotation of the motor output shaft is transferred to the pinion assembly and a disengaged state in which the rotation of the motor is not transferred to the pinion assembly. The cam operated engagement assembly may be operably coupled to the handle and the releasable coupling assembly to transition the releasable coupling assembly between the engages state and the disengaged state based on a position of the handle.
