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

PRECAUTIONS TO BE TAKEN : AM6 AUTOMATIC GEARBOX
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.
- Do not exceed 70 km/h (45 mph)over a distance of 100 km (60 miles)
maximum.
Driving.
Never drive with the ignition switched off.
NOTE:The automatic gearbox is only lubricated when the engine is
running.
Repairs on electrical components.
Do not disconnect:
- The battery when the engine is running.
- The ECU when the ignition is switched on.
Before reconnecting a switch, check:
- The condition of the various contacts (for deformation, corrosion etc.)
- The presence and condition of the mechanical locking.When performing electrical checks:
- The battery should be correctly charged.
- Never use a voltage source higher than 16V.
- Never use a test lamp.
Repairs on mechanical components.
Never place the gearbox on the ground without protection.
Do not use the unions on the gearbox as handles for moving the
gearbox.
It is imperative
that the converter retaining peg should be in place
when removing the gearbox.
It is imperativeto use the centring pegs to couple the gearbox on the
engine.
Remove the converter retaining peg before coupling the gearbox on
the engine.
Engines: ES9A - DT17BTED4Precautions to be taken

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.
