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).
