    en.wikipedia.org/wiki/Oil_pump_(internal...

    The oil pump is an internal combustion engine part that circulates engine oil under pressure to the rotating bearings, the sliding pistons and the camshaft of the engine. This lubricates the bearings, allows the use of higher-capacity fluid bearings , and also assists in cooling the engine.

    en.wikipedia.org/wiki/Automatic_transmission

    Made from petroleum with various refinements and additives, ATF is one of the few parts of the automatic transmission that needs routine service as the vehicle ages. The main pump which pressurises the ATF is typically a gear pump mounted between the torque converter and the planetary gear set. The input for the main pump is connected to the ...

    en.wikipedia.org/wiki/Automated_manual_transmission

    Automated manual transmissions can be semi-automatic or fully-automatic in operation. Several different systems to automate the clutch and/or shifting have been used over the years, but they will generally use one of the following methods of actuation for the clutch and/or shifting: hydraulic or electro-hydraulic actuation, [12] electro-mechanical, [13] pneumatic, [6] [14] [15] electromagnetic ...

    en.wikipedia.org/.../GM_Roto_Hydramatic_transmission

    The other disadvantage of Roto HydraMatic was the extreme oil pressures in the small 8" fluid coupling, which caused transmission leaks. All HydraMatic transmissions suffer some shift quality with today's ATF fluid. The original "Type A" fluid that these transmissions take is available only at O'Reilly Auto Parts.

  6. Transmission (mechanical device) - Wikipedia

    en.wikipedia.org/wiki/Transmission_(mechanical...

    In the early mass-produced automobiles, the standard transmission design was manual: the combination of gears was selected by the driver through a lever (the gear stick) that displaced gears and gear groups along their axes. Starting in 1939, cars using various types of automatic transmission became available in the US market. These vehicles ...

    The police package (9C1) B-body cars featured a First Gear Block Out (FGBO) Plate on the transmission housing to prevent drivetrain damage. The shift point for first to second gear is about 43 MPH (69 km/h) while second to third gear shift point is about 83 MPH (134 km/h) assuming a 3.08:1 differential and a 5,500 RPM engine speed limit.

    en.wikipedia.org/wiki/Manual_transmission

    A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually ...
