RECOMMENDATIONS - PRECAUTIONS (AL 4 and 4 HP 20 AUTOMATIC GEARBOXES)
Engines : 6FZ - RFN - RHZ - XFX - 4HX
Towing
The front of the vehicle must be raised in order to be towed.
If the front of the vehicle cannot be raised :
IMPERATIVE : - Put gear lever in position «N».
- Do not add any oil.
AL4 gearbox
- Do not exceed 50 km/h (30mph) over a distance of 50 km (30 m).
4 HP 20 gearbox
- Do not exceed 70 km/h (45mph) over a distance of 100 km (60 m).
Driving.
Never drive with the ignition switched off.
Never push the vehicle to try to start it;
(impossible with an automatic gearbox).
Lubrication
The automatic gearbox is only lubricated when the engine is running.Removing - refitting. (Automatic gearbox).
WARNING : Never place the gearbox on its lower casing
(risk of deforming the tray and damaging the hydraulic valve block).
Never use the connections as handles for raising, turning, holding or
pushing the gearbox.
ESSENTIAL :
- Fit the converter retaining peg while the gearbox is removed.
- Fit the centring peg to locate the gearbox on the engine:
(remove the converter retaining peg just before locating)
WARNING :With the emergency programme selected, an impact is
felt when changing from ‘‘P’’‘‘R’’or ‘‘N’’‘‘R’’.

RECOMMENDATIONS - PRECAUTIONS (AL 4 AUTOMATIC GEARBOX)
Engines : 6FZ - RFN - RHZ
Procedure to be followed prior to carrying out repairs on AL4 autoactive gearbox
CLUTCH
GEARBOX
DRIVESHAFTS
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/RandN/D.
Réception client.
Discuss with the customer, to find out all the malfunction symptoms..
Oil quality – Oil level.
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 quality.
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 de codes défauts.
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).
