Unexplainable Transmission Stutter... help?

TrailBeast said

OH, and one thing I wanted to mention is that you need to have that trans fully warmed up to see how it's going to not only shift, but when it's going to shift.
Cold, or not all the way warmed up fluid makes them shift earlier and softer.
About 10 minutes of driving should get it warmed up enough to see how it will normally act.

I drove my car around 40 minutes one day adjusting and adjusting then 30 minutes another day adjusting and adjusting.

So on those questions I asked you, I called transgo.

1. If no lockup converter don't drill.
2. If no hole L in VB no need for spring/ball and no need for drilling hole in passage. He said someone must have made a mistake and put a ball and spring in there at some time.
