tors are color coded. Now remove con-
nectors from switches. Unplug the wir-
ing harness from the case electrical
connector by prying the lock tab away
from the plug and pulling down on the
plug, do not pull on the wires. Re-
moving solenoid is not required, just tie
the wires up out of the way.
STEP 4. Remove all except the cen-
ter valve body bolt (See Fig. 2.) Begin-
ning with the mid 1987 model year, TH-
700’s have a tube crossing over the
valve body. This tube is removed by
simultaneously pulling both ends out of
their respective bores. With the tube
removed (if equipped) hold the valve
body up firmly with one hand and re-
move the remaining bolt slowly. There
are several check balls in the valve
body along with several pints of oil.
Have your drain pan ready to catch the
oil and check balls (should they fall
out.) Save all check balls in a safe
place where they won’t get lost.
STEP 5. Beginning mid 1987 model
year, TH-700’s have an auxiliary valve
body located where earlier models have
a cover plate (See Fig. 2.) Remove the
cover plate or auxiliary valve body. Be
careful not to drop the check ball lo-
cated in the auxiliary valve body (See
Fig. 8.) Remove the 1-2 accumulator
housing while holding the separator
plate up to the case. Then slowly lower
the separator plate and retrieve the
check balls located above the plate.
Make note of the color and location of
the 1-2 and 2-3 accumulator springs for
correct reassembly (See Fig. 10.)
