<VV> Vacuum valve modulator leak check

[Stephen Upham]

	I must be sleep walking.  Keeping up with a two year old most of the  
day will do that to you.  I just realized how inane my last post  
was.  No wonder I was confused by the table on p. 7-55 as it deals  
with the throttle valve pressure tests.
	I planned to do a vacuum modulator valve vacuum test.  I'm assuming  
that there is a leak in the connections of the line (if indeed this  
is the problem area) at this point as the modulator is new and the  
hose connections are, too.  In the manual on p. 7-34 it states, "The  
vacuum modulator can be checked with a vacuum source for leakage.   
However, leakage normally results in transmission oil pull-over and  
results in oil smokey exhaust and continually low transmission oil.   
No vacuum modulator repairs are possible; replace as an assembly  
unit."  I am not experiencing smoky exhaust, and the only  
transmission fluid loss that I'm experiencing is a faultily installed  
gasket (my learning experience) which has slow leaks on two of the  
bolts.   The new gaskets (ordered two) are on their way.   That  
checking description works for a mechanic, but not for a teacher.  I  
need a little better description of where to connect the Mytivac,  
what procedure on the shifter (L,D,N) to use, and what vacuum  
readings I should be seeing in those three positions if everything is  
normal.

Hope that makes better sense.
