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.

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.
