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.

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 levels 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, Oil change (for Scénic II)).
If there is no gearbox leak, look for a leak in the engine compartment.
If the leak is from the gearbox:
–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.
