17. Control Valve Assembly-Disassembly,
Inspection and Assembly
The complete control valve assembly for the
1963 Cadillac Hydra-Matic transmission consists
of three individual assemblies and two spacer
plates connected to a channel plate. In disassem-
bly and assembly procedures, each individual
body should be disassembled, cleaned and in-
spected, and assembled before going to the next
body. This should be done to avoid confusion of
component parts. The names of the individual
assemblies are: (1) Coupling Valve Body Assem-
bly, (2) Shift Valve Body Assembly, and (3) Manual
Valve Body Assembly.
a. Inspection of Complete Control Valve
Assembly or Individual Units
(After Disassembly)
1. Wash body castings, valves, and other parts
in clean solvent.
CAUTION: Do not allow valves to bump to-
gether, as this might cause nicks and burrs.
2. Inspect all valves carefully to make sure
that they are free from dirt and are not damaged
in any respect. If burrs are present, they should
be removed by a fine stone or fine grade of cro-
cus cloth and light oil. Be careful not to round
off shoulders of valves.
