The vacuum would not make the car start in a higher gear from rest... the vacuum sends a signal to a modulator that controls shift timing and comfort by acting on internal pressure. If the transmission IS doing that, trying to start in a higher gear, it would be a major internal issue and completely unrelated to vacuum or what the mechanic did.
There are linkage issues that can cause the sluggish behaviour you describe, but they would be constant, not come and go.
I was too hasty in declaring your performance problems as not vacuum-related. Now that you have the shutoff working, try taking the car for a drive.
