When reinstalling the bolts throughout this
procedure, ensure to use the correct bolt
dimension in each location.

7

Reinstall one bolt (1) (M6 X 1.0 X 47.5) hand tight in
the centre of the control valve body to hold it in place,
at location C as shown.

Figure 7C4 – 43

Fit a new shield (1) to the transmission fluid pressure
(TFP) manual valve position switch (2) and reinstall to
the control valve body.

N O T E

Refer to Figure 7C4 – 40 for bolt dimension and
corresponding location.

10

Reinstall the three long bolts (3) and the two short
bolts (4) hand tight only.

The control valve body bolts must be
tightened in an outward spiral starting from
the centre. Failure to follow this pattern may
distort the valve body causing the valves to
jam in their bores.

12

Follow the sequence starting from the centre as shown
by the arrows to tighten the following bolts to the
correct torque specification:

•

fourteen bolts (1) attaching the control valve
body,

•

five bolts (2) attaching the transmission fluid
pressure (TFP) manual valve position switch and

•

one bolt (3) attaching the manual detent spring.
