spring.
Fit the retainer plate and
secure with three screws.
5. Fit the 1-2, 2-3 valves (Fig.
28). Reposition the 1-2 spring,
plunger and valve in the upper
valve
body.
Also, refit the 2-3
plunger,
'spring
and
valve
in
the
upper
valve
body.
These
valves, springs and plungers are
of different diameter and cannot
be
confused.
Refit and secure
the retainer plates using three
screws and spring washers for each.
Torque to 20 to 30 in.
lbs.
Here,
again, the retainer plates arc dis-
similar and cannot be
confused.
Fit the range control valve and
retaining plug to the range control
body then fit the keep plate (Fig. 26).
6. Reposition the upper valve body
and the range control valve body on
the separator plate and secure with
eight screws, tightening them to a
torque of 20 to 30 in. lbs. (Fig. 30).
7. Replace the manual control
valve, downshift and throttle valves
(Fig.
26). The downshift and throttle
valve spring is interposed between
the two valves, locating in the
counter bore in the end of the down-
shift valve.
8. Reposition the downshift cam
and bracket with the cam in contact
with the downshift valve and secure
with two bolts. Tighten to 20 or
30 in. lbs.
9. Refit the oil tube collector and
secure with eight screws. Tighten
the screws to a torque of 20 to
30 in. lbs.
10. Refit the oil strainer ensuring
that it is fiat to
-h
in. concave and is
free from kinks.
TO REFIT THE VALVE
BODIES ASSEMBLY
1. If removed, replace the oil
pick-up tubes in the pump housing
(Fig.
30). The inner pair of tubes
are smaller in diameter than the
other two. One is a short straight
tube, the other is bent into several
planes with one end in the pump
housing and the other in the trans-
mission case. The outer tubes are
of different diameters and lengths
and cannot be confused or incor-
rectly fitted
.
2. Position the valve bodies as-
sembly, engaging the oil tubes in
the oil tube collector and making
sure the manual control valve is
engaged with the peg on the oper-
ating lever.
Secure the assembly
with three bolts, washers and spring
washers.
The two longer bolts
pass through the rear of the valve
bodies assembly and the shor!l.:r
bolt is positioned centrally just to
the rear of the filter (Fig. 26).
3. Reconnect the downshift valve
cable to the cam and check its
adjustment,
4. Fit the fluid transfer pipes
(Fig. 30). These pipes are a push
fit and are held in position by the
sump, when fitted. Each tube is
different in length and shape, and
is shaped in such a way that it
cannot be refitted incorrectly.
5. The front band should be
adjusted as previously described.
6. Refit the sump. Ensure that
the lower face of the transmission
and the sump flange are perfectly
clean.
Fit a new gasket and re-
place the sump.
Secure with fif-
teen bolts and spring washers,
tightening them evenly to a torque
of 8 to
10
ft.
lbs.
7. Check the rear band adjust-
ment.

8. Refill the transmission. Do not
add the quantity of oil required to
completely fill an empty transmis-
sion, since when the drain plug was
removed, the fluid from the conver-
ter was not drained. Check the level
when the gearbox is at normal
operating temperature.

Tubes
TO DISMANTI..E
TRANSMISSION
1. Remove the convertor from
the convertor housing, taking care
to ensure that the pumo driving
lugs are not damaged.
Note: The
torque convertor is still filled with
fluid
and therefore
precautions
should be taken to avoid spillage.
2. Remove the six bolts and
spring washers securing the con-
vertor housing to the transmission
case and remove the convertor
housing.
3. To remove the sump unscrew
the fifteen bolts and spring washers
around the sumo flange and remove
the sump together with its gasket.
Remove the fovr fluid transfer pipes
(Fig.
25), by prising out with the
protected blade of a screwdriver.
4. Withdraw the valve bodies
assemblv.
Disconnect the down-
shift valve cable from the cam.
Remove the two rear bolts hold-
ing rear end of valve bodies as-
sembly and the bolt just to the rear
of the pump filter (Fig.
25)
to remove
the valve bodies assembly, taking
care to draw this off evenly to
avoid damage to the pump tubes.
s;
Withdraw the four oil tubes
from the pump
adaotor.
It will
be seen that the outside pair are of
unequal diameter and therefore
cannot be fitted incorrectly.
The
inner pair are the same diameter,
the short straight one will pull out.
The long bent one may require the
adaptor on the outside of the trans-
mission case being loosened or re-
moved before this tube can be
removed.
6. Remove the four bolts and
spring washers securing the exten-
sion housing to the transmission
and carefully withdraw the exten-
sion housing rearward
.
7. The speedometer driving gear
is retained in one direction by a
circlip
and
driven and retained in
the other direction by a ball. Ex-
pand the circlip and remove.
Re-
move the speedometer driving gear
and ball.
8. Before removing the governor
it
should be noted that the small
rectangular plate secured by two
countersunk screws should face
rearwards
.
The drive for the gov-
ernor is transmitted through
a
ball
and, having removed the circlio
and drawn the governor rearwards,
