Transmission and work vehicle

A transmission comprising:

• a continuous speed variation mechanism including
• an input shaft,
• a first gear mechanism connected to the input shaft,
• a first output gear connected to the first gear mechanism,
• a second gear mechanism connected to the input shaft,
• a second output gear connected to the second gear mechanism, and
• a motor that is connected to the first gear mechanism and the second gear mechanism and continuously varies a speed ratio of the first output gear with respect to the input shaft and a speed ratio of the second output gear with respect to the input shaft;
• a first transfer shaft;
• a planetary gear mechanism that includes a first rotation element, a second rotation element, and a third rotation element, and is rotatable about the first transfer shaft;
• a second transfer shaft;
• a first driven gear that is rotatable about the second transfer shaft;
• and
• an output shaft,
• the first output gear being connected to the first rotation element,
