Carry out a converter stall test.
Follow the procedure in the Converter stall test section of the Workshop Repair Manual.
See the Taking line pressure section of the Workshop Repair Manual.
Set up the pressure gauge for a line pressure reading.
Warm engine with gearbox oil temperature between 60 and 80 ˚C.
Take the line pressure readings under the following conditions:
–with the gear lever in P or N and engine speed at 2000 rpm the pressure should be between 2.6 and 3.2 bar.
–with the gear lever at R and engine speed at 2000 rpm, the pressure should be above 4 bar.
–with the gear lever in D and engine speed at 2000 rpm, the pressure in first gear should be greater than 7 bar.
If the values are not correct, there is a fault inside the gearbox.
If the fault is still present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

COMMANDS AND CLEARING:
Before using these clearing commands, engine and vehicle speeds must be zero and the selector lever must be in
position P or N.
AC024 Sequential control of the actuators
This command activates sequence solenoid valves EVS1 to EVS6 simultaneously to check that they
operate correctly.
RZ004 Fault memory
This command clears present and stored faults from the automatic transmission computer.
RZ005 Self-adapting programs
This command enables the self-adapting programming to be cleared from the automatic transmission
computer, after reprogramming or after gearbox components have been replaced.
After running this command, carry out a road test with the vehicle before returning it to the customer.
This is because the automatic gearbox may malfunction during the time taken for the self-adapting
programs to reinstall.
RZ006 Converter lockup self-adapting program
This command clears the self-adapting programs associated with the converter.
After running this command, carry out a road test with the vehicle before returning it to the customer.
This is because, after the command, the automatic gearbox may malfunction during the time taken
for the self-adapting programs associated with the converter to reinstall.
RZ007 OBD memory
This command clears the computer's OBD memory.
AFTER REPAIRRepeat the conformity check from the start.

NOTESCheck the 20A permanent computer feed fuse marked 15 in the Protection and
Switching Unit. Check the cleanliness and condition of the connections.
Check the 5A after-ignition computer feed fuse marked 5H in the Protection and
Switching Unit.
Replace the fuses if necessary.
Check the cleanliness and condition of the connections.
Engine speed zero and gear lever in position P or N.
If the solenoid valves are not activated, check:
–the gearbox oil level,
–the cleanness and condition of the computer connector and modular connector,
Check the insulation, continuity and absence of interference resistance on the following connections:
●Connection code 5AU between components 119 and 754.
●Connection code 5AV between components 119 and 754.
●Connection code 5AW between components 119 and 754.
●Connection code 5AX between components 119 and 754.
●Connection code 5AY between components 119 and 754.
●Connection code 5DL between components 119 and 754.
●Connection code 5DM between components 119 and 754.
●Connection code 5BA between components 119 and 754.
●Connection code 5AZ, between components 119 and 754.
●Connection code 5DD between components 119 and 1019.
●Connection code 5DN between components 119 and 1019.
If the fault is still present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

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)).

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 gearbox malfunctions may be noted during gear changing without any fault being stored in the computer.
These malfunctions may be linked to:
–connection problems (insulation: generates 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.
If the fault is still present, contact Techline.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

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.

For a normal lever: check the play in the ball detent of fixed 1st gear. There must be little or no lever clearance in
this position.
For an inverted lever: check the play in the ball detent of fixed 1st gear. There must be little or no lever clearance
in this position.
