Replace vacuum servos for climate control

I have finally narrowed down why my tranny shifts rough... It's only when the climate control is on and its either on the bi-level, feet, or defrost positions. If it just blowing out the middle vents it shifts fine. But I cannot select anything other than the middle vents or it will shift rough until I start up next time. So I've concluded that the vacuum servos that control all of this are in need of replacement OR just need new rubber connectors or something.

Anyone done this? Do I have to take the whole dash apart to do this? Any info for me is GREATLY appreciated. I hadn't used the climate control for a couple weeks because I was enjoying smooth shifts all too much. I got the courage to use the AC today and it shifted just fine if not better with the middle vents running only.
