'57 Torqueflite (fluid w/water or coolant)

[Philippe COURANT <accf_clb@xxxx>]

Hi,
I've put some pics i took when we disassembled the transmission.
You'll see the worn front clutches and the color of the "fluid"
!! Yesterday i said "water" but perhaps it's "coolant" . As i
said a shop tested the radiator and there's no leakage.

If the replacement screws held, we have to conclude that the
failed screws
were the wrong grade of steel. I assume you are sure the
conversion from US
specs (inch pounds?) to European specs (dyne cm?) were done
correctly?
It seems that the screws were weaken (heat ?). The torque was 15
to 20 ft.lbs (we have a torque wrench with US scale) and the
screws broke before, perhaps at 5 ft.lbs.

B/T/W.......I wouldn't re-use the rear clutches, even if they
appeared good. The clutch materail is absorbent, and still could
be mixed with water. I'd not want to take a chance; changing
them is cheap compared to rebuilding again.

We've put new rear clutches (and new rings, new gasket, etc..)
