DRAINING, FILLING AND TOPPING UP THE AM6 AUTOMATIC GEARBOX
Tool.
[1] Filling cylinder: (-).0340
Respect the safety and cleanliness requirements.
Draining.
IMPERATIVE: Draining of the gearbox must be done with the oil hot (60°C minimum), in order to
ensure that the impurities in suspension in the oil are eliminated.
NOTE:Drainage is only partial, as the torque converter cannot be drained totally.
Raise the vehicle.
Remove:
- The oil level plug (2)by means of the Torx spanner.
- The drain plug (1)using a hexagonalspanner.
NOTE :Around 3 litresof oil should flow out.
Filling.
Fit the drain plug (1)(with a new seal).
Tighten the plug (1)to: 5 ± 1 mdaN.
Remove:
- The air filter housing.
- The oil filler plug (3).
Use tool [1].

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).

Thread of oil, then "drip-drip".
Refit the level plug (2).
Tighten the plug (2)to: 0.8 ± 0,1 mdaN.
"drip-drip" or nothing.
Refit the level plug (2).
Stop the engine.
Add 0.5 litreof extra oil into the gearbox.
Repeat the topping-up procedure.
NOTE:The level is correct when the thread of oil becomes "drip-drip".
Refit the level plug (2)(with a new seal).
Tighten the plug (2)to: 0.8 ± 0,1 mdaN.
Refit the filler plug (3)(with a new seal).
Tighten the plug (3)to: 4 ± 1 mdaN.
A level of oil that is too high can have the following consequences: Abnormal overheating of the oil, leaks of oil
causing a level which is too low resulting in destruction of the gearbox.

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.

GEARBOX
TRANSMISSION
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.
