IMPERATIVE: Respect the safety and cleanliness specific to high pressure diesel injection
engines.
Preliminary operations.
WARNING: Prior to any intervention, check the connections of the turbocharger pressure
regulation actuators.
NOTE:If an air flow fault is memorised by the diagnostic tool, refer to the chapter "Air flow from
the turbochargers".

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).
Engines: ES9A - DT17BTED4

DRAINING, FILLING AND TOPPING UP THE AM6 AUTOMATIC GEARBOX
WARNING: Do not take account of the information mentioned on tool [1].
Oil capacity for a dry gearbox: 7 litres (approx.).
Type of oil: JWS 3309 ESSO(red in colour).
Volume of oil remaining after draining: 4 litres (approx.).
Quantity of oil to be added: 3 litres (approx.).
Refit the filler plug (3)(with a new seal).
Tighten the plug (3)to: 4 ± 1 mdaN.
Initialise the oil usage counter (follow the procedure in the diagnostic tool).
Checking the oil level.
Prior conditions:
- Vehicle in a horizontal position.
- Check that the gearbox is not in back-up mode.
Remove the filler plug (3).
Add 0.5 litreof extra oil into the gearbox.
Press the brake, change through all the gears.
Gear lever in position "P".
Engine running, at idle:
- Oil temperature 60°C (+ 8 ; - 2)(parameter measures with a diagnostic tool).
- Remove the level plug (2).

CHECKING THE OIL PRESSURE IN THE AM6 AUTOMATIC GEARBOX
WARNING: Clean the flexible pipe of the tool [1] each time before use; the different
automatic gearbox oils cannot be intermixed.
Fit the tool [1]on the tool [2].
Perform the following operations:
- Raise the vehicle, wheels hanging.
- Apply the parking brake.
- Start the engine.
- Check the oil pressure.
WARNING: Wait for the gearbox oil to reach a temperature between 58°C and 68°C.
Check the level of oil in the gearbox (see corresponding operation).
NOTE:Check the temperature of the oil using the diagnostic tool in parameter measures.
Gear lever position: D.
Engine speed: Idling.
Principal oil pressure: 3.7 to 4.2 bars.

CHECKING THE OIL PRESSURE IN THE AM6 AUTOMATIC GEARBOX
Checking the torque converter.
WARNING: This check has to be of short duration (2 seconds), as it causes a rapid
rise in the temperature of the oil in the automatic gearbox.
Respect the following checking conditions:
- Engine at operating temperature.
- Gear lever in position D.
- Press on the brake pedal.
- Accelerate the engine to the maximum engine speed (see below).
Gear lever position.: D.
Maximum engine speed for ES9A : 2400 ± 50 rpm.
Maximum engine speed for DT17 : 2600 ± 50 rpm.
Diagnosis:
- If the maximum engine speed obtained is lower than the value indicated, the torque
converter is the cause.
- If the maximum engine speed obtained is higher than the value indicated, the automatic
gearbox is the cause (slipping).
Additional operations.
Remove tools [1]and [2].
Refit the screw (2), with a new seal.
Reposition the pipe (1).
Refit the air filter housing.
