A-999 A-904T – ATSG (Automatic Transmission Service Group)

A999 (later renamed 32RH) was a heavier-duty, wide-ratio version of the small-frame A904 transmission for use with medium-power V8 engines and the 3.9 L V6 engine. It was equipped with five direct friction plates. These automatics had lower first and second gear ratios to allow the lower-powered engines to provide better acceleration without sacrificing highway fuel economy.
