The 2004R is sort of a baby brother to the 700R4. It was used in cars with 4 and 6 cylinder engines with presumably less HP.
However, they were used in the Buick Grand National which set records at the strip. The 2004R is shorter and generally can be a direct replacement for a Powerglide or TH350. They can built for performance cars - IE: California Performance Transmissions (Art Carr) specializes in these units.
