ABSTRACT OF THE DISCLOSURE A transmission for use in a motor vehicle having a torque converter; and auxiliary speed change-gear assembly coaxial with the torque converter; an intermediate shaft extending through the auxiliary speed change-gear assembly; a countershaft extending in parallel to the intermediate shaft of the auxiliary speed change-gear assembly; and a final reduction-gear assembly for transmitting a driving force from the countershaft to wheel axles. The auxiliary speed change-gear assembly provides a plurality of forward speed range drives including overdrive and reverse drive and has an output driving gear. A driven gear is mounted on the countershaft and meshes with the driving gear. The trans- mission has at least one thrust bearing mounted on the intermediate shaft of the auxiliary speed change-gear assembly for rotably supporting the driving gear and a member threadably engaged into one end of an auxiliary speed change- gear assembly casing for asserting a predetermined force on the bearing supporting the driving gear. Preferably, the at least one bearing comprises a first pair of counterbalancing thrust bearings mounted on the intermediate shaft rotatably supporting the driving gear. A second pair of thrust bearings are provided for receiving thrust-reacting forces from the first pair of bearings. The force-exerting member is preferably threadably engaged into the one end of the auxiliary speed change-gear assembly casing remote from the torque converter, exerts a predetermined force on one bearing of the second pair, and is accessible from outside the casing.
