Where is all my Dextron II going?



Thanks all for the responses.

Well Rob, it turns out you were right.  The cooler hoses are routed on top 
of the left fender well and then down to the lower radiator.  I could not 
see any leak from there at first, but I could see the red fluid on the 
pavement.  At some point, I put the tranny in reverse (against an incline) 
and then I could see the fluid pouting from one of the hoses (could not see 
the leak in neutral, apparently there is no flow/pressure).  Its a real old 
hose, and the high heat just killed it off.  Fortunately, it did not start 
leaking till after the high speed run.  What I thought was P/S fluid, it 
was transmission fluid all along.  Later, the transmission cooled down, so 
it stopped spraying, but the leak continued.

So, all I have to do is replace that hose, and the lost fluid.  That will 
fix my problem.  I definitely need a transmission cooler, just like on my 
other 68.

Well, sorry, I meant Dextron III, not II.  Don't know nothing about these 
"secret" agents though.

That could have been another good possibility.  However, to the best of my 
knowledge, the Torquflite does not use vacuum for shifting control.  Am I 
right?

Another interesting note.  While messing with the hoses trying to figure 
out my leak (on a dark covered shelter trying to stay dry, its been raining 
most of the day here), I accidentally touched the fan of the running 440 
with my finger.  I was lucky though, no damage.  Did not even cause any 
pain.  I was surprised.  Lets try to be careful!
