A gear means of an automatic transmission for automobiles including a planetary gear means and friction engaging means in combination, a carrier of the planetary gear means being integrally combined with one of two relatively rotatable elements of the friction engaging means to provide an integral carrier assembly which in turn provides a planetary assembly by incorporating planetary pinions, wherein a rotary mass unbalance of the planetary assembly due to an asymmetrical arrangement of planetary pinions is compensated for by removing a part of the one of the two relatively rotatable elements forming a part of the carrier assembly. |
