Abstract
A vehicular transmission including an underdrive unit and an overdrive unit each having at least one planetary gear system including a sun gear, ring gear, planetary pinions and planetary carrier wherein an axial extension member integral with the output gear of the underdrive unit and an axial extension member integral with the input gear of the overdrive unit are axially engaged to counterbalance the thrusts of the planetary gear systems. The transmission also includes structures within the overdrive planetary gear system and between the overdrive planetary gear system and gear transmitting output of the overdrive unit to the vehicle wheels for counterbalancing their respective thrusts.
