What to look for when inspecting A833OD?

Main thing to check on these particular 4 speed's is wear and slop in the input shaft bearing area in the main case. These tend to wear in that area and get sloppy. Brewers performance has a hardened ring to fix this problem. I would just get a rebuild kit from Brewers, and replace all the bearings and seals, also check all the brass, and gears for wear. The are how to articles above on doing this stuff, check them out also.
