NOTESOnly refer to Customer complaints after carrying out a complete fault finding
procedure with the diagnostic tool and the conformity check.
If the engine races when shifting from 1/2 when cold (automatic transmission oil
temperature lower than 15˚C), replace the pressure modulating solenoid valve
(EVM).
Use the diagnostic tool to check the
consistency between the display and the gear
lever positions (ignition on and engine
stopped).Adjust the control settings following the instructions
provided (see MR 370, Mechanical, 23 A,
Automatic Transmission, Automatic
transmission control unit (for Mégane II and
Scénic II)).
Are they consistent?
Check the oil level and the condition of the oil
(colour, odour, etc.).Replace the automatic transmission (see MR 364,
Mechanical, 23A, Automatic transmission,
Removal-Refitting (for Mégane II) and MR 370,
Mechanical, 23A, Automatic transmission,
Removal-Refitting (for Scénic II)). Does the condition of the oil suggest there
is an internal fault in the automatic
transmission?
With the engine stopped, check the line
pressure information provided by the pressure
sensor (PR003 Oil pressure).Replace the pressure sensor (see MR 364,
Mechanical, 23A, Automatic transmission,
Pressure sensor (for Mégane II) and MR 370,
Mechanical, 23A, Automatic transmission,
Pressure sensor (for Scénic II)). Is the value higher than 0.2 bar?

Check the oil level.
Check the oil pressure value using PR003 Oil pressure:
Warm engine with gearbox oil temperature between 65 and 90˚C.
Measure the line pressure under the 3 following conditions:
Important
The vehicle must be stationary: handbrake on and brake pedal depressed, no accessories operating
(e.g.: air conditioning)
1engine speed idling:
Shift the gear lever to R, N and D, the pressure reading must be greater than 2.5 bars.
2engine speed at 1200 rpm:
–gear lever in R position, the pressure reading must be greater than 4 bars.
–gear lever in D position, the pressure reading in first gear must be greater than 5.5 bars.
3engine speed at 2200 rpm:
–gear lever in R position, the pressure reading must be greater than 11 bars.
–gear lever in D position, the pressure reading in first gear must be greater than 11 bars.
Do the recorded values correspond to the specified values?
Shift the gear lever into position D and monitor
PR007 Turbine speed when accelerating.Replace the pressure modulating solenoid valve and
the oil. Repeat the check after replacement.
If the fault is still present, replace the hydraulic
distributor and all the solenoid valves (see MR 364
Mechanical, 23A, Automatic transmission,
Hydraulic distributor (for Mégane II) and MR 370
Mechanical, 23A, Automatic transmission,
Hydraulic distributor (for Scénic II)).
Does the turbine speed change?

Replace the automatic transmission (see MR 364, Mechanical, 23A,
Automatic transmission, Removal-Refitting (for Mégane II) and
MR 370, Mechanical, 23A, Automatic transmission, Removal-Refitting
(for Scénic II)).

Refer to the procedure and the safety instructions for carrying out a setting point check on the torque converter.
Theoretical engine speed at setting point: 2300 ± 150 rpm
Is the value of the setting point wrong or is there an internal noise in the converter?
Carry out a road test, observing the engine
speed on the instrument panel and the
information displayed on the diagnostic tool
(PR006 Engine speed)Replace the torque converter, the lock-up solenoid
valve and the oil. If the oil is burnt, also replace the
hydraulic distributor and all the solenoid valves
(see MR 364 Mechanical, 23A, Automatic
transmission, Hydraulic distributor
(for Mégane II) and MR 370 Mechanical, 23A,
Automatic transmission, Hydraulic distributor
(for Scénic II)).
When replacing the torque converter, ensure that the
reaction shaft is securely attached to the hub of the
oil pump (flanged shaft).
Note:
A setting point which is too low may be due to a lack
of engine power. Does the engine speed change each time
there is a gear change?

The checks carried out have not provided any
evidence of a fault and the automatic
transmission appears to be working correctly.
If the vehicle does show the customer complaint
selected, continue with the entire fault finding
procedure. Replace the hydraulic distributor and all the solenoid
valves. (see MR 364 Mechanical, 23A, Automatic
transmission, Hydraulic distributor
(for Mégane II) and MR 370 Mechanical, 23A,
Automatic transmission, Hydraulic distributor
(for Scénic II)).

ALP7 Oil present under vehicle
NOTESOnly refer to Customer complaints after carrying out a complete fault finding
procedure with the diagnostic tool and the conformity check.
Check the colour of the oil under the vehicle to determine the source of the leak (automatic transmission fluid is
red).
Clean the engine and gearbox.
Check the oil level in the engine and gearbox.
Top up if necessary (see MR 364 Mechanical, 23A, Automatic transmission, Filling-levels (for Mégane II) and
MR 370 Mechanical, 23A, Automatic transmission, Draining-Filling (for Scénic II)).
If there is no gearbox leak, look for a leak in the engine compartment.
If the leak is from the gearbox side:
–Locate the source of the leak and carry out the necessary repairs.
–Replace any faulty parts.
–Check the oil level.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
