INSTALLATION:
NOTE
After ‘Transmission Control Unit’ dismounting
the relevant screws must be discarded too.
Verify that the electro valves, pressure sensor
and ground tab connections does not show
any visible anomalies in displacement or
damaging.
Verify the right cleanliness of the electro valve
block on the ‘Transmission Control Unit’
mating side. No contamination from foreign
materials is acceptable (oil, dust, metal burrs,
etc.). If necessary, cleaning process must be
previously approved by ‘MAGNETI MARELLI’.
Position the ‘Transmission Control Unit’ over
the electro valve block, still using for

parallel towards the mating surface. Insertion
of all the electro valves, pressure sensor and
ground tabs must be obtained by appropriate
load on the ‘Transmission Control Unit’ heat
sink and following handling precautions.
Once the ‘Transmission Control Unit’ is
positioned mated to the electro valve block,
remove the two threaded rods.
Insert the new four ‘Transmission Control
Unit’ fixing screws into the corresponding
holes and tighten each screw by applying a
torque of 6.0 ± 1.2 Nm, following the order
shown in the image below. Please consider
