I think I may have gone too far with modulator adjustment car shifts fine part throttle but at wot in d it won't catch second until I lift off the throttle

Good video but the little edit, vacuum modulators don’t determine shift point. The modulator determines softness or hardness of the shift. The governor in the tail housing determines shift point.

That would be the timed port on the carb id suspect
