Parts to be replaced after they have been
removed :
- roll pin,
- lock nuts,
- copper seals.
AD4 automatic transmission uses two grades of oil and has two levels.
MECHANISM : ELF RENAULTMATIC D2 (D20104).
In emergency, use:
- MOBIL ATF 220 D (D 20104 or D 21412).
-
TEXAMATIC 4011.
FINAL DRIVE: TRANSELF TRX 75W 80W.

The mechanism is drained during the major service.
The oil level must be checked every 10000 miles (15 000 km) in case there is a slight oil leak.
The final drive is never drained ; it is filled for life.
The strainer is no longer replaced (NT 2261A).
Only the level may change due to a slight leak.
Oil capacity
NOTE :if the automatic transmission is replaced, only check the oil level since the transmission is supplied by
the Parts Department full of oil.

Fault warning light
MESSAGE FROM THE ELECTRONIC FAULT
WARNING LIGHT
Normal operation :
• The warning light is not illuminated during
normal operation whether the vehicle is being
started, engine running or when the vehicle is
stationary.
Presence of a fault :
• Vehicle stopped, engine running, or when
driving, warning light permanently illuminated
• Vehicle moving, warning light illuminates and
extinguishes without action at the ignition key.
• Vehicle moving, warning light illuminates
briefly.Oil temperature < - 20 °C or > + 140 °C
• Vehicle moving or stationary, warning light
flashes at a rate of approximately 1 flash per
second, in this case, reduce the performance
requirement by moderating acceleration.

Oil pressure
Before starting:
- if the gearbox has been drained, fill it with 3.5
litres of oil,
- if you are simply checking the level, you must
add 0.5 litre of the recommended type of oil.
1-Vehicle on a 4 post lift, transmission at am-
bient temperature.
2-Start the engine with the selector lever in the
Park position.
3-Connect the
XR25 test kit and enter:
D14then
#0 4
4-Raise the vehicle and allow the engine to run
until it reaches a temperature of 60 °C.
5-When the desired temperature has been rea-
ched, open the top-up plug; allow the excess
oil to overflow (must be more than 0.1 litre)
for approximately 20 seconds. Replace the
plug
6-If the volume of oil which flowed out is less
than 0.1 litre, the level is not correct. Repeat
the operation.
In this case, add 1 litre of the recommended oil
and allow the transmission to cool down between
successive operations.

Filling - Levels
23
FILLING - TOPPING UP
Filling is performed though tube (D).
Use a funnel fitted with a 15/100 filter so as to
prevent any impurities entering.
The level
MUST be checked in accordance with the
following method:
94845R1
The transmission is fitted with an oil pressure
take-off. Connect the B.Vi. 1215 to check the
automatic transmission pressure sensor only.
The oil pressure cannot be altered.
Its value is determined by the electronic compu-
ter.

Hydraulic Distributor

On versions with ABS
Refit the mounting nut
(C) from the ABS electro-
pump unit on the rubber mounting.
94933R
Refit:
- the plastic shield in the front left wheel arch,
- the front left hand wheel,
- the air filter,
- the expansion bottle.
Fill with oil and check the level.
NOTE :every time the hydraulic distributor is re-
placed or removed, replace the modulating sole-
noid valve filter, the strainer and its seal.

ENGINE
Separate the gearbox from the engine by :
- removing the starter motor,
- removing the bolts from the automatic trans-
mission sump.
Remove:
- the hoses on the exchanger, Lift the engine from the sub-frame.
91131S
- the converter bolts
- the bolts around the gearbox and the TDC sen-
sor.
Separate the automatic transmission from the en-
gine.
REFITTING (special notes)
Refit the converter by positioning it with respect
to the mounting bolts.
Tighten the bolts around the automatic transmis-
sion.
Refitting is the reverse of removal.
Aligning the engine sub-frame with the body will
be made easier by positioning two approximately
100 mmlong threaded rods in the two front sub-
frame-body mountings.
Tighten the sub-frame front mounting bolts to a
torque of 6 daN.m. and to a torque of 11 daN.m at
the rear.
Tighten all nuts and bolts to the re-
commended torque.
Fit the caliper mounting bolts using Loctite
FRENBLOC and tighten them to the correct tor-
que.
Press the brake pedal several times to bring the
pistons back into contact with the brake pads.
Fill:
- the cooling circuit and purge it (see chapter 19),
- the engine with oil if necessary.
NOTE : check that the steering shaft yoke spacer is
in place when refitting.

REFITTING
The lip seal (oiled) is positioned using toolB.Vi.
1322 (this determines the correct position of the
seal).
SPECIAL TOOLING REQUIRED

output seals

Refit the protective heat shield in the opposite or-
der to removal using a 45 mm diameter socket.

2)REPLACING THE O-RING
The principle is the same on both sides, but only
one side must be removed at a time.
Special notes:
The is no flange on the driveshaft outputs, but ins-
tead a simple splined end piece protected by a
shield.

REFITTING
Refit the nut, turning the same number of turns as
when it was removed.
Align the marks made on the nut and the sump.
Replace the bolt (D) and the locking plate (E).
Refit the shield after having replaced the lip seal if
necessary (see paragraph 1).
Fill the final drive with oil.
95791-2R
REMOVAL
Drain the final drive and remove the shield, as ex-
plained in paragraph 1.
Locate the position of the nut (F) with respect to
the sump by putting a mark on one of the teeth
and on the face of the sump.
Remove bolt (D) and the locking plate (E) from the
nut using tool B.Vi. 1323, remove the nut, coun-
ting the number of turns it takes.Replace the O-ring on the nut, cleaning the seat
properly and lubricating the new seal with final
drive oil.

Wiring
23
The new generation of A4.2 automatic transmission is fitted with monoblock wiring which means that many
of the intermediate connectors are no longer required. As a result, the method for repairing sensors or
switches is different.

2 - Oil pressure sensor
3 - Electro-hydraulic interface (sealed connector)
