In common with many happy souls on this forum, I too am spending all my idle hours wondering how I can tweak my tranny. I have always had a soft 3-4 shift, and have my modulator turned up to keep it acceptably firm. That, of course, means I get a too-hard 2-3 shift. 1-2 is perfect and all downshifts are fine.
Question: Should there be a vacuum/pressure line from the inlet manifold to the modulator vacuum, to provide a control input from turbo boost? Mine has a line from the inlet manifold to the ALDA, but no connection to the trans modulator.
Also does anyone have a schematic for the hydraulic valve logic in the valve body?
