14. Control Valve Body
A: PRECAUTION
The control valve is composed of parts which are
accurately 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 shouldbe 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.
