How would you guys pursue a THM400 restoration?

Hi everyone !

I'm faced with a dilemna and I need some assistance from
you guys.

About 8 months ago, I purchased an original CX coded THM400
for my 69 L/78 Camaro. It is one of those Holy Grail items.


The transmission was a low mile take-out ( about 18,000 )
and had been sitting with no fluid in it for about 30 years.
I have to expect that the internals are in need of attention
at this point in time. I don't want to install this THM400
and then find out I have problems. What do you think?

In any event, I want to get this THM400 restored to it's
original specifications. I was given the name of a shop in
the mid-west to perform the restoration through a member
here. Here essentially is my problem. I really don't know
much at all about the internals of the CX, but I do know
that they are special ( extra clutches, special governor,
etc. ). How can I be sure that I get my real CX internals
back from the restoration shop? I don't want to be overly
paranoid, but it took me many years to get this one and I
just want to be as cautious as is prudent.

How do you guys think I should proceed? BTW, I don't want
to question the integrity of the shop I am considering, so
I won't mention their name.
