Abstract
An automatic transmission for an automotive vehicle includes multiple planetary gear units, each including a sun gear, a ring gear surrounding the sun gear, a set of planet pinions continually engaged with the sun gear and ring gear, and a planet carrier rotatably supporting the planet pinions. Various brakes selectively hold elements of the gear units against rotation and several clutches releasably interconnect elements of the, gear units. A torque converter is adapted to produce a hydrokinetic drive connection between the crankshaft of an engine and the input shaft of the transmission, or to mechanically connect those components when a bypass clutch of the torque converter is engaged. Various elements of the planetary gear units are permanently driveably connected mutually.
