    摘要： An improved strutless synchronizer has an annular spring interposed between an internally splined sleeve, mounted for axial sliding movement on a main shaft, and an associated blocking ring. Selected ones of the sleeve splines are formed at the extremities with radially inwardly extending teeth. Each of the teeth has a dual chamfered face portion in opposed relation with the annular spring. The blocking ring has three equally spaced lugs each formed with a transverse groove sized to axially capture the annular spring so as to allow the spring freedom to rotate in its grooves relative to the blocking ring. Each time the sleeve is moved toward meshed engagement with an associated main shaft ratio gear its spline teeth chamfered faces compress the spring at random points thereby minimizing spring wear. Also, the grooves, by positively retaining the spring, insure instant unloading of the blocking ring.

    摘要： A valve assembly in a fluid system of a vehicle transmission directs fluid flow from a fluid source to at least one fluid actuated device. The assembly includes a first solenoid-actuated valve for directing fluid flow to a first fluid actuated device and a second solenoid-actuated valve for directing fluid flow to the first fluid actuated device. A manually actuated manual valve in the transmission is moveable for directing fluid flow from a fluid source to either the first or second solenoid-actuated valves in the hydraulic circuit, when the manual valve is actuated, which permits the vehicle to operate in various gears or operating modes as desired.

    摘要： The present provides a shutdown shift schedule which allows a vehicle driver an increased number of gear states to increase driveability. This method monitors the gear state conditions indicative of the gear state which said automatic transmission is in. When the shift state conditions vary from predetermined standards, the controller uses the shutdown shift schedule in place of the shift schedule for changing gears of the automatic transmission. This shutdown shift schedule is adapted to allow a 3-1 shift when the shift solenoid is in a shift D position and the shift state is 3. The shutdown shift schedule is also adapted to allow a 3-2 shift when the shift state is 3 and the shift solenoid is in the shift 2 position.

    摘要： An electronic transmission coastdown shift control method in which the transmission controller has the capacity to predict timing of apply element application. The control method of the present invention improves the shift sequence by accurately prefilling the apply element. The transmission controller vents the release element when apply element application is imminent and controls the application of the oncoming element to achieve a controlled element exchange for a smooth coastdown shift. A duty cycle is then applied to complete the oncoming element application with a soft yet quick application and control the engagement of the oncoming element. The identification of the application point of the oncoming element enables the apply element fill volume to be learned during coastdown shifts. It also enables the calculation of a line pressure correction factor necessary in accurately predicting application of the apply element. Anticipation of a coastdown tip-in condition is also provided. When a tip-in condition is sensed, a more aggressive fast fill of the apply element is undertaken in order to handle an approaching input torque increase.
