<VV> Modulator valve vacuum specs

[Stephen Upham]

O.K. Let me put this another way.  Is the operating vacuum on the  
modulator supposed to be starting at 12 HG and pulled in all the way  
at 15 HG?  I tested the new modulator that I had on the shelf (I  
ordered two from a reputable east coast vendor at the time of  
replacement and I assume that they will be within the same specs).   
I'll need to create a wrench to remove the modulator in order to  
check the one on the car.  It started to move at 16 and was full open  
at 20.  If the other is of the same ilk, and this is an unacceptably  
high vacuum range, that might explain why the transmission will kick  
like a mule in changing from d to l when coming to a slow stop and  
being barely noticeable when I apply a hard brake just before the  
downshift (I've increased the vacuum pressure to meet the faulty  
specs?).
