 It uses a three-element, welded assembly diameter torque converter mounted remotely on the rear face of the differential, (that also incorporates the starter ring gear, and a centrifugal fan baffle for cooling, via slots in the engine bellhousing) and is driven directly from the engine crankshaft by a flexplate inside the engine bellhousing.The selector quadrant is arranged R-N-D-L, or Reverse, Neutral, Drive and Low, with no "Park" (except in Pontiac's 1963 version, redesigned to handle the increased torque of a new V8 engine in Tempest and LeMans, added by means of a separate lever).Range selection is via dash-mounted selector lever operating a sheathed cable that moves a spool valve range selector in the transmission valve body.
