164 Automatic Transmission Concerns/Questions

["Antonio Riso" <riso@domain.elided>]

Hello all,

My 164 automatic transmission went south 
for no apparent reason (I baby my cars!).   The transmission that I had 
installed works fine now, but I'm afraid that the elusive 
gremlin might zap this one as well.

Recently,  someone on the Digest pointed out something 
that got my attention.  The function of the thermo-valve to allow the 
cooling of the oil.  I could not follow what was said about its function 
and/or malfunction.  So, I'm hoping that the person that posted the question 
(or anyone that knows  how the valve works)  would reply.  If the 
thermo-valve functions as a thermostat, I'm intersted in knowing at 
what temperature it is should open.  Also, there are two switches on  
on the transmission.  One activates the fan and the other turns on 
the Max oil temperature light.   They have different trigger points.  
How can you distinguish the two?  The wires can easily be interchanged. 
I'm not sure what might be wrong, but it would help to know what 
to look for.

Thanks for your time
Antonio
