Replacing the transmission computer:
Remove the automatic transmission computer (see MR 370 mechanical, 23A, Automatic transmission,
Automatic transmission computer, Removal - Refitting).
Refit the automatic transmission computer (see MR 370 mechanical, 23A, Automatic transmission,
Automatic transmission computer, Removal - Refitting).
Establish dialogue with the diagnostic tool.
Use command VP001 Enter VIN.
Run command VP009 Write last After-Sales Service operation date.
Do not carry out any automatic programming if replacing the automatic transmission computer. Automatic
programming is finalised when the vehicle is driven.
In order to optimise the automatic programming before delivering the vehicle to the customer, apply the
"Programming procedure" shown below.
Replacing the hydraulic distributor:
Remove the transmission hydraulic distributor (see MR 370 mechanical, 23A, Automatic transmission,
Hydraulic distributor, Removal - Refitting).
Refit the transmission hydraulic distributor (see MR 370 Mechanical, 23A, Automatic transmission, Hydraulic
distributor, Removal - Refitting).
Replacing the automatic transmission
Remove the transmission (see MR 370,Mechanical, 23A, Automatic transmission, Removal - Refitting).
Refit the transmission (see MR 370, Mechanical, 23A, Automatic transmission, Removal - Refitting).
Establish communication with the diagnostic tool.
Initialise all the programming, use the command RZ009 Self-adapting clearing (Vdiag05 only).
Run command VP009 Write last After-Sales Service operation date.
The self-programming functions are performed when the vehicle is being driven.
In order to optimise the automatic programming before delivering the vehicle to the customer, apply the
"Programming procedure" shown below.
* APV: After-SalesPROGRAMMING PROCEDURE:
Programming conditions:
The automatic gearbox oil temperature should be between 60˚C and 100˚C.
Stationary, engine running, brake pedal depressed:
Engage neutral at least 5 times to consolidate the programming.
While driving:
Engage the same gear at least 5 times (i.e. in the same conditions) to consolidate the programming.
Note:
Gear changes are slow and harsh the first few times the vehicle is driven, until the automatic transmission computer
has carried out its automatic programming.
During upshifts and downshifts, the system analyses variations in oil pressure, components (play in the brakes and
clutches, changes to spring stiffness due to ageing) and input torque, then corrects them in order to maintain the
quality of gear changes.
The system analyses the turbine speed during the 3 phases of drag reduction (selection of Neutral when stationary,
regulation during drag reduction and deselection of Neutral) and corrects this speed by adjusting the converter
lock-up solenoid valve pressure.

If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.

NOTESConditions for applying fault finding procedures to stored faults:
The fault appears after:
1st case: when driving, in Drive or in Manual
ratio > ratio setpoint,
and output speed ≥ 300 rpm,
and turbine speed ≥ 300 rpm,
and engine speed ≥ turbine speed - 50 rpm,
and (if 1st with engine braking, accelerator pedal ≥ 6.25 % OR,
if 1st, accelerator pedal ≥ 30.75 % OR,
if 2nd to 6th accelerator pedal ≥ 6.25 %).
2nd case: while driving, reverse gear
ratio > ratio setpoint,
and output speed ≥ 300 rpm,
and turbine speed ≥ 300 rpm,
and engine speed ≥ turbine speed - 50 rpm,
and accelerator pedal ≥ 6.25 %.
3rd case: stationary, in Drive or in Manual
Difference between engine speed and mapping > threshold,
and engine speed increases constantly for 250 ms.
4th case: stationary, reverse gear
Difference between engine speed and mapping > 0,
and engine speed increases constantly for 250 ms.
System effects:
No engine torque transmitted to wheels.
Switch to defect mode occurs during vehicle speed safety conditions (vehicle speed
< 32 mph (54 km/h)).
The system effects will vary depending on which solenoid valve is faulty:
–If caused by brake 2 solenoid valve, system switches to fixed 2nd, 3rd or 5th gear
safe mode.
–If caused by clutch 2 solenoid valve, system switches to fixed 2nd, 3rd or 6th gear
safe mode.
–If caused by the clutch 3 solenoid valve, system switches to fixed 2nd, 3rd, 4th or 5th
gear safe mode.
–If caused by clutch 1 solenoid valve, system switches to fixed 3rd, 5th or 6th gear
safe mode.
In all cases, restarting is in 3rd gear.
If vehicle stopped in Drive, system switches to fixed 5th gear if engine speed is lower
than 2000 rpm.
If vehicle stopped in "R" mode, switching to "R" mode is done if engine speed is less
than 2000 rpm.
In reverse, moving off when "kick-down" detected.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by another
check with the diagnostic tool.

TORQUE CONVERTER
Note:
Status ET071 "Torque converter" is applicable to the following sub-function:
–"Gear changes".
STATUS
DEFINITIONOPEN: shows that the torque converter is not locked up.
SLIPPING: shows that the torque converter is in a phase between open → lock-up or
in a phase between lock-up → open.
CLOSED: shows that the torque converter is locked up.
INVALID: shows that the torque converter is faulty.
NOTESSpecial notes:
Apply the conformity check to see if the statuses are consistent with the operating
programs of the system.
Note:
In manual mode, the torque converter is always locked up.
Conformity check with engine stopped and ignition on.
OPEN
Engine stopped, in position "N", status ET071 "Torque converter" must be "OPEN".
In the event of a fault, consult the interpretation of fault DF097 "Torque converter
lock-up".
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
