TURBO HYDRA-MATIC 200
7A1-73
4. In next bore up, install low overrun clutch valve,
longer stem end out, low overrun clutch spring and coiled pin.
5. In next bore up, install intermediate boost valve,
longer stem end out, intermediate boost spring and coiled pin.
6. In lower right bore, install throttle valve, smaller
outside diameter land first, making sure valve is seated at the
bottom of the bore. Install inner coiled pin between the lands
of the valve (Fig. 7A1-177). Install the detent pin into the
shift T.V. spring and install these 2 parts into the bore. Install
the throttle valve plunger, stem end first, into the throttle
valve plunger bushing and install these 2 parts into the bore,
valve end first. Install outer coiled pin from rough cast
surface side, aligning pin with slot in bushing.
NOTE:
The detent pin is used only on BR, CN, CU, CX
and CZ models. All other models do not use a detent
pin.
7. In next bore up, if removed, install shift T.V. valve,
larger outside diameter stem end out, shift T.V. spring and
coiled pin. Then, using plastic hammer, install new shift T.V.
plug flush with rough casting surface.
8.
In next bore up, install reverse boost valve, stem end
out, reverse boost spring, reverse bore plug, hole side out and
coiled pin.
9. In next bore up, install 1-2 shift valve, longer stem end
out, making sure valve is seated at the bottom of the bore.
Install 1-2 throttle valve spring into the 1-2 throttle valve
bushing and 1-2 throttle valve, stem end first, into the
bushing. Install these 3 parts, valve end first, into the bore,
aligning bushing so the coiled pin can be installed in the pin
slot. (See Fig. 7A1-178 for pin slot and identification of 1-2
throttle valve bushing.)

10. In next bore up, install 2-3 shift valve, longer stem
end out, making sure valve is seated at the bottom of the bore.
Install 2-3 throttle valve spring into the 2-3 throttle valve
bushing and 2-3 throttle valve, stem end first, into the
bushing. Install these 3 parts, valved end first, into the bore,
aligning bushing so coiled pin can be installed in the pin slot
(Fig. 7A1-179).

11. Install manual valve with the inside detent lever pin
groove to the right.
12. If removed, install new seal ring on 1-2 accumulator
piston.
13. Oil and install 1-2 accumulator piston, spring pocket
side out, into 1-2 accumulator piston bore of valve body.
CONTROL VALVE ASSEMBLY
Installation
1.
Inspect 1-2 accumulator spring for damage.
2. Install 1-2 accumulator spring into case (Fig. 7A1-
1 80).
3. Inspect control valve assembly and spacer plate for
damage (Fig. 7A1-181).
NOTE:
The size of the 5 check balls used in the case
and control valve assembly is 6.35mm (.250"). The size
of the check ball used in the pump is 7.14mm (.28lV).
Do not interchange.
4. Install 5th check ball in case as shown (Fig. 7A1- 182).
5. Install 2 guide pins as shown in Fig. 7A1-185.
6. Install 4 check balls into ball seat pockets in control
valve assembly and retain with petrolatum (see Fig. 7A 1-1 83
for check ball location).
7. Place the control valve assembly to spacer plate gasket
marked "VB" on the control valve assembly.
8.
Place the valve body spacer plate on the gasket marked
"VB".
9. Place the spacer plate to case gasket marked "C" on
the spacer plate (Fig. 7A 1
-
184).
10. Insert 2 control valve assembly to case attaching
bolts through the control valve assembly, gaskets and spacer
plate; and install these parts, aligning the manual valve with
the detent lever pin (Fig. 7A1-185).
NOTE:
Make sure check balls, 1-2 accumulator piston
and manual valve do not fall out.
