help needed with 904

Okay now for pictures of transmission number one it's the cleanest and of course it could have been rebuilt by Speed Shop for heavy-duty use? I'm wondering if there's anybody who was looking at the valve body can one see any problems? I could see that there were differences, But I figured that could just be from one year to the next. All the bolts and screws were of a different kind and some of the spring mechanism seem to work differently or work just a little different? Again that could just be from one year to the next I don't know anything about these Transmissions. Would be nice to know that someone recognizes something that is performance-oriented? Is there an obvious sign of a shift kit or something like that I should be looking for because Lord knows I would rather spend the $41 now and by some stupid shift kit now then have to do it later....
