Shift Kit

I seem to remember that making the 2-3 shift real stiff was harmfull to something.
(Don't remember what or why though)
Maybe just kinda hard on the direct clutches?
Not to make anyone nervous or anything I have also seen small diameter blocking rods go right through the accumulator cover part on the valve body on a hard 1-2 shift.

Ah, I see the rod has been addressed already.
