Planetary gear train of automatic transmission for vehicle

A planetary gear train of an automatic transmission for a vehicle comprising:

• an input shaft configured to receive torque of an engine;
• an output shaft configured to output torque;
• a first planetary gear set including first, second, and third rotation elements;
• a second planetary gear set including fourth, fifth, and sixth rotation elements;
• a third planetary gear set including seventh, eighth, and ninth rotation elements;
• a fourth planetary gear set including tenth, eleventh, and twelfth rotation elements;
• a fifth planetary gear set including thirteenth, fourteenth, and fifteenth rotational elements;
• a first shaft directly connected with the third rotation element and the input shaft;
• a second shaft directly connected with the fourteenth rotation element and the output shaft;
• a third shaft directly connected with the fifth rotation element and the thirteenth rotation element;
• a fourth shaft directly connected with the second rotation element, the eighth rotation element, and fifteenth rotation element;
• a fifth shaft directly connected with the ninth rotation element and the eleventh rotation element;
• a sixth shaft directly connected with the first rotation element and the fourth rotation element;
• a seventh shaft directly connected with the sixth rotation element;
• and
• a plurality of shafts selectively and respectively connected with a transmission housing while directly and respectively connected with at least one rotation element of remaining rotation elements of the third and fourth planetary gear sets that are not connected to any shaft of the first, second, third, fourth, fifth, sixth and seventh shafts, and the third shaft configured to selectively connected to the transmission housing.
