The modulator is at the back of the trans. It adjusts how "hard" the shift is. If the vacuum line falls off, the trans will shift very hard all the time - not neck-snapping, but more aggressively than normal. It does not impact shift points (rpm), that is completely controlled by the governor. I'm guessing something more in the realm of a sticky idle motor.
