Multiple gear transmission comprising input and output shafts ( 1, 2 ), three planetary sets (P 1 , P 2 , P 3 ), six rotatable shafts ( 1, 2, 3, 4, 5, 6 ) and six shifting elements ( 03, 04, 05, 14, 16, 56 ). Selective engagement of the shifting elements produces seven forward and two reverse gears. The input shaft is connected with the sun gear of the first planetary set (P 1 ), the output shaft with the web of the second planetary set (P 2 ), the third shaft ( 3 ) with the sun gears of second and third planetary sets (P 2 , P 3 ), one shaft ( 4 ) connects the web of the first planetary set (P 1 ) with the ring gear of the third planetary set (P 3 ), one shaft ( 5 ) is connected with the ring gear of the first planetary set (P 1 ), one shaft ( 6 ) connects the web of the third planetary set (P 3 ) with the ring gear of the second planetary set (P 2 ).
