Quoted from the Wiki site... "
A999 (32RH)
The
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.
Frequently used today in drag racing."
And similar in uses to the older 2-speed Powerglide automatic from GM, like my '57 Chevy had, which was also a popular choice for dragsters.
