    What modulator colors do what and turning the screw which way does what? The rod behind the modulator does it have a spring to dampin shifts like a th350, so if so i can remove it for firmer shifts? What is the best c4 upgrade for the money to help shifts

    Street/strip valve body from Performance Automatic, gets rid of the flair on the 2nd to 3rd shift.

    The green stripe modulator is the only one that I know is adjustable... IIRC you turn the screw clockwise and it should raise the shift points. Counterclockwise will lower the shift points and make it shift sooner.
