RECOMMENDATIONS/PRECAUTIONS : AL4 AUTOMATIC GEARBOX
Precautions to be taken
Repairs on mechanical components.
Never place the gearbox on the ground without protection.
In order to avoid breaking the input shaft ring, it is imperative
that the
converter retaining bracket should be in place when handling the
gearbox.
It is imperative
to use the centring peg and the converter retaining
bracket to couple the gearbox on the engine.
After coupling the gearbox on the engine, remove the centring peg. Modification of the oil usage counter value.
Exchanging the gearbox ECU:
- Note down the gearbox counter value.
- Transfer the value read into the the new gearbox ECU.
Exchanging the gearbox:
- Initialise the oil usage counter to 0.
Draining the gearbox:
- Initialise the oil usage counter
(follow the diagnostic tool procedure).

RECOMMENDATIONS/PRECAUTIONS : AL4 AUTOMATIC GEARBOX
Procedure to be followed prior to carrying out repairs on AL4 autoactive gearbox
If a gearbox malfunction occurs, there are two possible configurations
depending on the seriousness of the fault:
- Gearbox in back-up mode with a replacement programme of
(the fault
values are taken in substitution).
- Gearbox in back-up mode with an emergency programme (3rd hydraulic).
WARNING: In the emergency programme, an impact is felt when
changing P/R, N/R and N/D.
Réception client.
Discuss with the customer, to find out all the malfunction symptoms.
Oil quality - Oil level.
Oil quality.
If the gearbox has suffered a serious fault resulting in a malfunction or
the destruction of a clutch, the oil will overheat and become
contaminated with impurities: the oil is said to be «burnt».
This is characterised by a black colour and the presence of an
unpleasant smell.
ESSENTIAL: The gearbox must be replaced.Oil level
(see corresponding operation).
An excessive oil level can result in the following consequences:
- Excessive heating of the oil.
- Oil leaks.
An insufficent level causes the destruction of the gearbox.
Top up the level of oil in the gearbox
(if necessary).
Check using a diagnostic tool.
Read the fault codes
(engine and gearbox).
Absence of fault codes.
Carry out parameter measures, actuator tests and a road test.
Presence of fault codes.
Carry out the necessary repairs.
Delete the fault codes.
Carry out a road test to check the repair and, if need be, modify the
gearbox ECU parameters
(this is essential after an initialisation of the
ECU).

BRAKES
BLEEDING AND FILLING THE BRAKING SYSTEM
Bleeding the braking circuit with the bleed apparatus.
Connect the bleed apparatus [1]on the brake fluid reservoir (4).
Adjust the apparatus pressure to 2 bars.
For each brake circuit:
- Couple a transparent tube on the bleed screw.
- Submerge the other end of the tube in a clean container.
- Open the bleed screw.
- Wait until the brake fluid flows out without air bubbles.
- Close the bleed screw.
- Remove the bleed apparatus [1].
Check the level of the brake fluid
(between the «DANGER»level and the «MAXI»level).
Fill if necessary with the the approved and recommended synthetic brake fluid.

BRAKESBLEEDING AND FILLING THE BRAKING SYSTEM
Bleeding the braking circuit without the bleed apparatus.
NOTE:Two operators are necessary.
For each brake circuit:
- Apply the brake pedal to place the circuit under pressure.
- Couple a transparent tube on the bleed screw.
- Submerge the other end of the tube in a clean container.
- Open the bleed screw.
- Wait until the fluid flows out without air bubbles.
- Close the bleed screw.
NOTE:Recommence the process a second timeif that is necessary.
Check the level of the brake fluid
(between the «DANGER»level and
the «MAXI»level).
Fill if necessary with the the approved and recommended synthetic
brake fluid.Bleeding the secondary braking circuit.
WARNING: During the bleed operations: take care to maintain the
level of the brake fluid in the reservoir, keep it topped up.
NOTE:The bleed apparatus [1]is still connected on the brake fluid
reservoir (4).
Use the diagnostic tools [2]or [3].
Select the menu corresponding to the vehicle:
- ABSmenu
(according to equipment).- ESPmenu (according to equipment).
Follow the instructions of the diagnostic tool.
At the end of the bleed programme, check the level of the brake fluid,
top up if necessary.
Check the travel of the brake pedal: it must not be excessive. If it is,
restart the bleed procedure.
