Your 1992 Ford explorer w4.0L won't shift into second unless you do it manually then when you try to shift into drive it downshifts and its full of fluid and its a fresh rebuild what could the problem?

Vacum line is off of the modulator. The modulator is located behind a plate on the passenger side of the tranny near the rear Cat. If there is fluid in the line, then you will most likely need to replace the modulator.
