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)).
