PRECAUTIONS TO BE TAKEN

Towing

REMOVING - REFITTING. (Automatic gearbox).

The front of the vehicle must be raised in order to be towed.If the front

of the vehicle cannot be raised :

WARNING : Never place the gearbox on its lower casing (risk of

deforming the tray and damaging the hydraulic valve block).

IMPERATIVE : - Put gear lever in position "N".

- Do not add any oil.

- Do not exceed 50 kph over a distance of 50 km.

Never use the connections as handles for raising, turning, holding or

pushing the gearbox

Driving.

ESSENTIAL :

Never drive with the ignition switched off.

Never push the vehicle to try to start it;

(impossible with an automatic gearbox).

- 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)

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.

Engines : NFU - RFN - RHZ

PROCEDURE BEFORE REPAIRS

Oil level AL 4 (prior conditions).

AL 4 gearbox only

- Vehicle in horizontal position.

- Check gearbox is not in back-up mode.

- Remove the oil filler plug (3).

- Add 0.5 litres extra oil into the gearbox.

- Foot on the brake, change through all the gears.

- Selection lever in position "P".

- Engine running, at idle.

- Oil temperature : 60°C (+8°C; -2°C), measured with the aid of a diagnostic tool.

- Remove the oil level plug (3).

- Thread of oil then "drip-drip" : refit plug (3). Tighten 2.4 m.daN.

- "Drip-drip" or nothing : refit the plug (3).

- Stop the engine.

- Add 0.5 litres extra oil into the gearbox.

- Repeat the oil level procedure.

NOTE : The level is correct at the moment the thread of oil becomes drip-drip.

- Refit the oil filler plug (3). Tighten to 2.4 m.daN.

- Initialise the oil usage counter (open the diagnostic tool procedure).

RECOMMENDATIONS - PRECAUTIONS (AUTOMATIC GEARBOX - AL 4 )

Engines : NFU – RFN - RHZ

PROCEDURE BEFORE REPAIRS (continued)

When the ECU detects an erroneous or absent valueon input or

output :

Reading the fault codes.

Read the fault codes.

- It writes the fault in memory.

- Absence of fault codes:

- For each associated context, it writes the context of the oldest fault

in memory.

- Carry out a measure of parameters.

- It initiates a back-up mode strategy.

Presence of anomalies:

There are two types of back-up modes :

- YES : Carry out the necessary repairs.

- NO : Read the fault codes - engine ECU

- Carry out a road test.

- The ECU makes replacement values available (relating to comfort,

gear selection quality, loss of functions).

Following an initialisation of the ECU, for a certain period of time there

may be an inconsistent gear selection quality (while ECU parameters

are adapting to the gearbox).

- Access to emergency programme (only 3rd gear and reverse are

available)

To achieve a consistent standard, it will be necessary to carry out a

road test taking in frequent gear changes (auto-adaptive laws).
