IDing trans upgrades?

[Reaper450128]

OK, since I have the "new" transmission (production # 268555 I think, or another words one of the originals from the 1992MY) I thought I would try and determine what parts have been/need to be upgraded on it. Is there any way to tell which modifications have been made by looking at the parts? I'll take pictures if it will help anyone identify anything, but I'd rather not take it apart if I can avoid it, so the internal components age may have to remain a mystery.

Also, can anyone decipher the TSB on the upgrades and tell me which upgraded components exist in final design? I'm having difficulty figuring out what parts may or may not supercede others, and which go on the SVX and not on the other vehicles covered by the TSB. Link to TSB
