    Abstract: An automatic transmission uses 6 shift elements applied in combinations of four to establish ten forward speed ratios and a reverse speed ratio. The automatic transmission uses a hydraulic control system to control engagement of the six elements, control engagement of a torque converter bypass clutch, control engagement of a parking pawl, and to provide fluid for a hydrodynamic torque converter and for lubrication. The parking pawl is disengaged in response to engagement of two of the six shift elements and remains disengaged in response to engagement of other shift elements. A single valve controls several different functions associated with the two-pass torque converter. Pressurized fluid is provided by a variable displacement engine driven pump and also by an electric pump. A priority valve reduces lubrication flow when other fluid demands are high as indicated by the pump displacement control circuit.

    Abstract: A transmission includes a hydraulically actuated park valve with two spools in a common housing. One of the spools engages and disengages the park mechanism in response to manipulation of line pressure and engagement of specified shift elements. A pin selectively engages this spool to hold it in position. The valve is designed such that friction holds the spool in position in the absence of hydraulic pressure or electric power. The second spool controls an out-of-park circuit such that the park mechanism remains disengaged when desired. The two spools are separated by a compression spring.

    Abstract: A transmission includes a latch valve with latched and de-latched states. In the de-latched state, the latch valve directs a control pressure to a clutch apply circuit. In the latched state, which is entered in response to a control pressure higher than a latch pressure, the latch valve directs a line pressure to the clutch apply circuit. A controller manages the transition from latched to de-latched differently depending upon the transmission input torque and gear state. At high transmission input torque, the controller first reduces the control pressure to rapidly accelerate a spool in the latch valve, and then increases the control pressure to prevent clutch slip. At low torque, the controller reduced the pressure to an intermediate value during the transition and then reduces it again. At moderate torques, the controller reduces the pressure directly to a target pressure in a single step.

    Abstract translation: 变速器包括具有闩锁和非锁定状态的闩锁阀。 在解锁状态下，闩锁阀将控制压力引导到离合器施加电路。 在响应于高于闩锁压力的控制压力而进入的闩锁状态下，闩锁阀将线路压力引导到离合器施加电路。 控制器根据变速器输入扭矩和档位状态管理从锁定到非锁定状态的转换。 在高变速箱输入扭矩时，控制器首先降低控制压力，快速加速滑阀中的阀芯，然后提高控制压力，防止离合器打滑。 在低扭矩时，控制器在转换期间将压力降低到中间值，然后再次减小。 在中等转矩下，控制器将压力直接降低到目标压力的一个步骤。
