  2. Automatic transmission fluid - Wikipedia

    en.wikipedia.org/wiki/Automatic_transmission_fluid

    Automatic transmission fluid (ATF) is a hydraulic fluid that is essential for the proper functioning of vehicles equipped with automatic transmissions. Usually, it is coloured red or green to differentiate it from motor oil and other fluids in the vehicle. This fluid is designed to meet the unique demands of an automatic transmission.

  3. SH-AWD - Wikipedia

    en.wikipedia.org/wiki/SH-AWD

    VTM-4 was designed with a special lock mode to assist when a vehicle is stuck in the snow. This lock mode automatically engaged power to all four wheels at low speeds. As speeds increased, the power to the rear wheel would decrease, and by 18 mph, the system would revert to front-wheel drive.

  4. DEXRON - Wikipedia

    en.wikipedia.org/wiki/DEXRON

    This fluid was better suited for the higher fluid temperatures caused by the unique torque converters [7] [8] [9] and higher power engines of the day. The fluid specification was revised again in 1958, 1959, and 1960. [10] GM continued the licensing program, allowing oil companies to produce the new Type "A" suffix "A" fluid under their own ...

  5. Comparison of pumps - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_pumps

    Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...

  6. GM Roto Hydramatic transmission - Wikipedia

    en.wikipedia.org/wiki/GM_Roto_Hydramatic...

    The original "Type A" fluid that these transmissions take is available only at O'Reilly Auto Parts. There were two models of the Roto Hydramatic: the lightweight Model 5 , which weighed 145 lb (66 kg) and had ratios of 3.03, 1.58, and 1.00, and the larger Model 10 , which weighed 154 lb (70 kg) and had ratios of 3.50, 2.93, 1.56, and 1.00.

  7. Working fluid selection - Wikipedia

    en.wikipedia.org/wiki/Working_fluid_selection

    The choice of working fluids is known to have a significant impact on the thermodynamic as well as economic performance of the cycle. A suitable fluid must exhibit favorable physical, chemical, environmental, safety and economic properties such as low specific volume (high density), viscosity, toxicity, flammability, ozone depletion potential (ODP), global warming potential (GWP) and cost, as ...

  8. Ultramatic - Wikipedia

    en.wikipedia.org/wiki/Ultramatic

    McFarland, his assistant John DeLorean, and their team had not been satisfied with the improved pick-up of the Gear-Start Ultramatic, and modified the angle of the converter "pump" to allow a higher stall speed thus increasing the torque multiplication better suited to the torque curve of the new V8 engines.

  9. Centrifugal pump selection and characteristics - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_pump_selection...

    While centrifugal pumps impart momentum to the fluid by motion of blades, positive displacement pumps transfer fluid by variation in the size of the pump’s chamber. Centrifugal pumps can be of rotor or propeller types, whereas positive displacement pumps may be gear-based, piston-based, diaphragm-based, etc.
