types of transmissions with only one fluid[79]. In this field, tailor-made individual lubricant designs are being developed for specific transmission types. Gearlubricationoils for motor cars are under continuous development with the object of improving reliability, driving comfort and increasing oil-...
All 10R140 transmissions require MERCON Ultra Low Viscosity (ULV) automatic transmission fluid. The low viscosity lubricant minimizes parasitic power waste through the transmission by reducing pumping and windage losses. MERCON ULV is not cross-compatible with previous or coinciding MERCON ATF products, ...
1. In a vehicle having an engine and an automatic transmission system including a fluid actuating device being movable for applying at least one friction element, at least one solenoid-actuated valve being movable in response to the presence or absence of electrical power to the valve for directi...
Referring now to the drawings, particularly to FIG. 1, there is schematically shown an automatic transmission to which the present invention can be applied. The transmission includes a torque converter 10 and a transmission gear device 20. The torque converter 10 is of a conventional three element...
shows that there is a convertor fault. A high stall speed points to a problem with the fluid supply to the convertor, or to an internal fault in the rest of the transmission. To find out exactly where the problem lies, you will need to do the tests shown in the faultfinder chart ...
Flow chart of torque phase shift adaptation. Full size image Adaptive control strategy for the inertia phase The electro-hydraulic control system of the transmission is a typical time-delay nonlinear system. In order to prevent the system from running out of control, only one parameter is adjusted...
FIG. 5 shows a control flow chart for the synchronous shift control of the present invention when the OGC is slipped during a torque phase. It describes a systematic approach to enable the shift control shown in FIG. 4. As previously stated, one of the advantages of this invention is the...
The step-pattern in the chart is a result of how the Fed sheds Treasury securities. It doesn’t sell them outright but allows them to “roll off” when they mature. Treasuries only mature mid-month or at the end of the month. Hence the stair-steps. In mid-July, no Treasuries matured...
the command is executed414. Execution of some of the commands are indicated in the flow chart as separate steps, such as: to end416; and to perform calibration steps418. Others are indicated by routings to stages in the overall operation already identified, such as: to reinitialize406; rese...
FIG. 1 is a flow chart diagram of one embodiment of a method for positioning a Doppler gate in spectral Doppler ultrasound imaging; FIG. 2 is a graphical representation of an example spectrum; FIG. 3 is a graphical representation of example parallel beamforming in a region of interest; ...
