A manual planetary power transmission includes two planetary gearsets and three torque-transmitting synchronizer assemblies. Two of the synchronizer assemblies permit the control of one gear member of the planetary gearsets individually. The third synchronizer permits control of two of the planetary gear members individually or simultaneously. The three synchronizer assemblies are manipulable in combinations of three to provide six forward speed ratios and one reverse speed ratio in the planetary gearsets.

A control valve apparatus for a rotating clutch includes a valve having a spool portion and a mass portion. The spool portion provides a control function to distribute pressure from a static source to a chamber of the clutch. The valve also has a mass associated therewith which is responsive to rotation of the clutch and valve apparatus such that the apply pressure and the centrifugal effective pressure operating on the valve and the mass centrifugal force is compensated for to maintain the pressure at a specific radius of the clutch equal to the static apply pressure of the pressure source independent of rotation speed.

A planetary transmission has a plurality of rotating-type torque-transmitting mechanism that are operable to connect a rotating input mechanism with one or more planetary gear members. At least two of the rotating-type torque-transmitting mechanisms are radially stacked and axially aligned. At least one of the radially stacked rotating torque-transmitting mechanisms has an apply piston that is slidably mounted in a stationary transmission housing, an apply plate that is rotatable with a portion of the torque-transmitting mechanism, and a bearing disposed therebetween to accommodate relative rotation therebetween.

A vehicle powertrain incorporates a planetary gearset which is coupled with a front wheel drive mechanism and a rear wheel drive mechanism. The planetary gearset is controlled by two torque-transmitting mechanisms to establish an input member of the planetary gearset as well as a grounded member for the planetary gearset in combinations that will provide a two-wheel low drive ratio, a two-wheel high drive ratio, a four-wheel low drive ratio, and a four-wheel high drive ratio.

A planetary transmission includes four planetary gearsets, two of which are simple planetary gearsets and two of which are compound planetary gearsets. A first of the planetary gearsets has members selectively connectible with a ground or stationary member through a synchronizer clutch. A second, third, and fourth of the planetary gearsets have at least one member continuously interconnected with a ground or stationary member. A plurality of synchronizer clutches are employed between the planetary gearsets, which are manipulatable to establish at least seventeen forward speed ratios and one reverse speed ratio between an input shaft and an output shaft of the transmission.

A planetary transmission has a plurality of torque-transmitting synchronizer mechanisms that are controlled to engage and disengage positions. The control of the torque-transmitting synchronizer mechanisms is accomplished through a plurality of cam slots and control rods that are disposed between a control mechanism and each of the torque-transmitting synchronizers to enforce engagement and disengagement of the synchronizers.

A planetary gear arrangement for a multi-speed power transmission has a carrier assembly with a plurality of pinion gear sets wherein each set has one long pinion and three short pinions. The long pinion meshes with two short pinions and a ring gear. The third short pinion meshes with a sun gear and one of the short pinions. The other two short pinions mesh with a ring gear and a sun gear, respectively. The carrier and both sun gears are connected with selectively operable rotating torque transmitters and the carrier, one sun gear and one ring gear are connected with selectively operable stationary torque transmitters while the other ring gear defines an output member for the planetary gear arrangement.

A valve is positioned by a control diaphragm which senses manifold pressure in an automotive engine and by an opposing biasing spring to create a control pressure, and a servo diaphragm positions the throttle in response to variations in the control pressure to thereby maintain the manifold pressure at a value determined by the spring bias. The vehicle operator positions the accelerator pedal to vary the spring bias and thus determine the value at which the manifold pressure is maintained.

A shift mechanism for a manual planetary transmission has a plurality of control members. Each control member has a slot configuration for each shift rail defined therein. The slot configurations are aligned among plates and a pin member is inserted in each of the slot configurations. Manipulation of any one of the plates produces movement of two or more of the pin members. The pin members are operable upon movement to select the engagement of the synchronizers, which are disposed within a power transmission. The synchronizers establish drive ratios between the input shaft for the transmission and the output shaft for the transmission.

A powertrain has a power transmission including a pair of planetary gearsets. The planetary gearsets are selectively interconnectible with an input shaft through a plurality of synchronizer mechanisms to provide ten forward speed ratios and two reverse speed ratios.
