Repair.
Respect the precautions to be taken prior to any operation:
- The front flexible pipe must be protected against any external mechanical damage.
- The front flexible pipe must not come into contact with corrosive products.
- Do not deform the front flexible pipe more than 20°angular (X), 20 mm axial, 25 mm shearing
(Y)(front flexible pipe removed).
- Do not deform the front flexible pipe more than 3°angular (X), 0 mm axial, 3 mm shearing (Y)
(front flexible pipe in place).
WARNING: Non-respect of these precautions will shorten the life of the flexible pipe.
It is therefore imperative to disconnect or remove the exhaust line for any operations
necessitating lifting of the engine-gearbox.

SPEEDOMETER
An E.E.C. decree of 25 June 1976, regulates the speed displayed by the speedmeter in relation to the actual speed travelled.
This decree stipulates:
- The speed indicated by a speedometer must never be lower than the actual vehicle speed.
- Between the speed displayed «SD»and the speed travelled «ST», there must always be the following relationship:
ST < SD < 1.10 ST + 4 Kph
Example:For an actual speed of 100 Kphthe speed displayed by the speedometer may be between 100and 11 4 K p h.
The speed indicated by the speedometer may be influenced by:
- The speedometer.
- The tyres fitted to the vehicle.
- The final drive ratio.
- The speedometer drive ratio.
Any of these components can be checked without removing them from the vehicle (see information note N° 78-85 TT of 19 October 1978).
NOTE:Before replacing the speedometer, check the conformity of the following points:
- The tyres fitted to the vehicle.
- The gearbox final drive ratio.
- The speedometer drive ratio.

GEARBOX
TRANSMISSION
PROCEDURE PRIOR TO OPERATIONS: AM6 AUTOMATIC 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 or N/R.
Reception of the customer.
Discuss with the customer, to find out all the malfunction symptoms.
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.
Preliminary conditions:
- Vehicle horizontal, parking brake off.
- Check that the gearbox is not in back-up mode (using a diagnostic tool).
- The oil temperature should be 60°C (+8, -2)(using a diagnostic tool).
- Press on the brake pedal, change through all the gears.
- Place the gear lever in position P.
With the engine running at idle, without power consumers (aircon,
heating, etc.):
- Remove the oil level plug.
The oil should flow out, then drip-drip.
Refit the oil level plug (the oil level is correct).
The oil does not flow out through the oil level plug (see operation: drain
fill - bleed the gearbox).
