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.

GEARBOX
TRANSMISSION
AM6 GEARBOX CONTROLSThe gear selector is guided by the shape of the stepped gate and by a retaining spring which
pulls it to the left hand side.
The gear control has 5 positions:
- Position "P": parking (locking and immobilisation of the vehicle).
- Position "R": reverse gear.
- Position "N": neutral.
- Position "D": drive (for use of the 6 gearsin autoadaptive automatic operation).
- Position "M": manual (this position allows the driver to select his gears in one-touch mode by
pulling "M -"or pushing "M +"on the gear selector).
NOTE:Only positions "P"or "N"authorise starting of the engine.
In position "M", the selection is enabled by an electronic sensor located close to the gear
selector:
- The variation of flux necessary to affect the sensor cells is obtained by a magnet on the lever
opposite the cells, provoking the changes of status.
- The information on this is transmitted to the gearbox ECU.

AM6 GEARBOX CONTROLS: «SHIFT LOCK» FUNCTIONIMPERATIVE: Respect the safety and cleanliness requirements, with reference to the brochure:
«Recommendations-Precautions».
The «shift lock»is a system that locks the gear selection lever in position «P».
Unlocking the «SHIFT LOCK»(normal operation).
Switch on the ignition.
Press the brake pedal and keep it pressed.
Move the gear selection lever out of position «P».
Unlocking the «SHIFT LOCK» (with an operating fault).
Should it be impossible to unlock the «shift lock»with the «Normal operation»method.
The fault may originate from one of the following components:
- «Shift lock».
- Gear lever position switch.
- Automatic gearbox ECU.
- Electrical harness.
- Battery voltage.
Operations to be performed.
Unclip the cover (1).
Unlock the «shift lock»by pressing at "a"with the aid of a screwdriver (screwdriver with a minimum length of
150 mm).
Move the gear selection lever out of position "P".

PROCEDURE FOR INITIALISATION OF THE AUTOMATIC GEARBOX ECU
NOTE:For all these operations, follow the procedure in the diagnostic tool.
Replacement of the automatic gearbox without replacement of the ECU.
Carry out the following operations:
- Initialisation of the neutral position of the gear selection lever position sensor.
- Initialisation of the adaptation of the oil pressure regulators and electrovalves.
- Initialisation of the autoadaptatives.
- Resetting the oil usage counter to zero.
Replacement of the automatic gearbox ECU.
Carry out the following operations:
- Read the value of the gearbox oil usage counter from the old ECU.
- Write the value of the oil usage counter into the new ECU.
- Initialisation of the neutral position of the gear selection lever position sensor.
- Initialisation of the adaptation of the oil pressure regulators and electrovalves.
- Initialisation of the autoadaptatives.

TRANSMISSION
PROCEDURE FOR INITIALISATION OF THE AUTOMATIC GEARBOX ECU
Replacement of the automatic gearbox and of the automatic gearbox ECU.
Carry out the following operations:
- Initialisation of the autoadaptatives.
- Resetting the oil usage counter to zero.
- Initialisation of the adaptation of the oil pressure regulators and electrovalves.
Draining of the automatic gearbox oil.
Carry out the following operations:
- Initialisation of the adaptation of the oil pressure regulators and electrovalves.
- Resetting the oil usage counter to zero.
NOTE:If downloading the automatic gearbox ECU, there is no specific operation, follow the procedure in the diagnostic tool.
IMPERATIVE: For a certain time, having carried out an ECU initialisation procedure, one may obtain gear changing quality that is more
or less good (adaptation of the ECU parameters to the gearbox). To improve the quality, it is necessary to perform a road test with
frequent changing through the gears (auto-adaptive laws).
