<VV> ADDING COOLING LINES TO CAR PG possible problem

[N2VZD at aol.com]

 This is just a rough outline from memory , without going to my notes and  
books!
JUST adding the pump cover to a car powerglide will not do the job. You  
need to make a filler for one of the voids in the pump  ( in the powerglide  
book sold by Corvanatics) or change the complete pump assembly.
I did one with a poured lead filler years ago , but best way is the  
complete pump. There are 3 different pumps out there , somewhere ( I am very  
frustrated trying to find a series of pictures I did on this subject years ago  
for a tech session) Contrary to what some people will tell you , I have had 
at  least 3 different pumps on the bench at the same time for pictures. 
There are  slight changes in the casting of the pump or cover.
 If things are not right , you are wasting your time putting the cover  on. 
I will try harder to find more on this subject soon. There is a lot to it  
you will miss by not reading up on it. You must also take readings of the 
stack  of components , to determine shims needed also. wrong guess may shorten 
life of  a lot of internals. If wrong , when you bolt trans to differential 
it will be  too loose (sort of OK) , or too tight (a real NO NO)
  There are also slight important differences in holes in the pump and  
cover. If you have several apart , look carefully at the pump body.
One problem , if overlooked will render a cooler useless. You can tell by  
driving the car a while , then put your hand on the cooler. If it is cold , 
you  goofed.  I hope this saves you from problems.

 most of my knowledge comes from mistakes...thank god most were  somewhere 
else!
