摘要： A fluid pressure control system for controlling an automatic transmission, which includes a gear transmission mechanism and several fluid pressure actuated friction engaging mechanisms, and which is shifted to various speed stages including an overdrive speed stage, a directly connected speed stage, and a reduction geared speed stage which is the closest speed stage below the directly connected speed stage, according to selective supply of actuating fluid pressure to the friction engaging mechanisms. The control system includes a governor pressure control valve, a throttle pressure control valve, a first shift valve for upshifting and downshifting between the directly connected speed stage and the overdrive speed stage, and a second shift valve for upshifting and downshifting between the reduction geared speed stage and the directly connected speed stage. These shift valves shift according to balance relationships between the throttle pressure and the governor pressure. The direct/overdrive shift valve has very considerable hysteresis in its operation, so that in the shift diagram the downshift line from the overdrive speed stage to the directly connected speed stage is generally to the high throttle opening low vehicle speed side of the upshift line from the reduction geared stage to the directly connected speed stage.

摘要： A transmission for use in a motor vehicle having a torque converter; an 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 transmission has at least one thrust bearing mounted on the intermediate shaft of the auxiliary speed change-gear assembly for rotatably 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.
