The original A-833's were a heavy duty 4 speed with conventional gearing. They even made a super strong version for the Hemi cars.
The version we are talking about, they flipped the gear clusters to give an overdrive, resulting in a super low 1st gear. Most of them are aluminuim, not cast iron cases (it appears the 4wd version may be cast iron), and will flex under heavy load, causing the shfts to go out of alignment. The revised shafts are much weaker than the original version. One of the shift levers is flpped to make this work.
GM offered them behind 4.3's and 305's, plus the 6.2 diesel which was desinged to match the 305 in power. They are not a high torque drag race capable trans like the original A-833! Big block and slicks = bang!
