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 less 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

Check the oil level.
Check the oil pressure 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,

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,

ALP4 Automatic transmission malfunctioning on gear changing
NOTESOnly refer to Customer complaints after carrying out a complete fault finding
procedure with the diagnostic tool and the conformity check.
Automatic transmission malfunctions may be noted during gear changing without any fault being stored in the
computer.
These malfunctions may be linked to:
–connection faults (insulation: creates a fault, resistance) in the sequence solenoid valve control wiring
harnesses (EVS1 to EVS6).
Check the tightness and condition of the clips on all the solenoid valve control wiring connections from the
computer to each solenoid valve.
Use command AC024 Sequential actuators control to find any faults.
–Hydraulic distributor faults (hydraulic slide valve seizing, strainer/distributor seal) preventing the sequence
solenoid valves from working properly.
Check the oil's condition (colour, burnt or not) its level and pressure: increasing with engine/turbine speed.
–Loss of pressure when changing gear (clutch brakes/cylinder leaks)
Read the values of the following parameters (gear lever in position D or R: vehicle stationary and handbrake
applied) on the CLIP tool:
–PR003 Oil pressure,
–PR006 Engine speed,
–PR007 Turbine speed,
–PR138 Reference pressure,
–PR008 Computer feed voltage.
These parameters are associated with automatic transmission operation.
If one of the values is incorrect, note the fault it causes.
Replace the faulty part if necessary and carry out a check.
If the fault is still present, contact Techline.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
