6. Control Valve Body
The control valve is composed of parts which are accu-
rately machined to a high degree and should be handled
carefully during disassembly and assembly. As these parts
are similar in shape, they should be arranged in neat order
on a table after disassembly so that they can be easily
installed to their original positions. Spring loaded parts
should be also handled carefully, as springs may jump out
of place when the parts are disassembled or removed.
Extreme care should be taken so as not to drop valves on
the floor. Before assembling, the parts and valves should
be dipped in a container filled with the ATF. Make sure that
the valves are clean and free from any foreign material
before assembly. Torque specifications should also be
observed.
