Draining and filling transmission oil

REQUIRED TOOLS

• [1]. Oil level gauge (ref. 168 589 01 21 00).

OIL CHANGE AND FILTER REPLACEMENT

• Remove the engine undershield.
• Clean the area around the oil pan and the drain plug (1) (Fig.2).
• Remove the drain plug (1) and drain the oil.

Fig. 2

• Remove:

• the oil sump (2),
• the filter (3).

• Replace:

• the drain plug seal,
• the filter (3),
• the seals (4),
• the 'gel' magnets (5) and refit the magnet cover plates.

Filling and checking the oil level

• Open the engine hood.
• Remove the cap (1) from the oil filler tube (2) (fig. 3). To do this, break the plate (3) and drive out the pin (4) left inside the cap (1).
• Fill the gearbox with oil, adding the same quantity as was drained.
• Start the engine and run it at 2,000 rpm for 3 seconds.
• Apply the parking brake.
• With the engine at idle, shift repeatedly through all gear ranges.
• Selector lever in position 'P', run the engine at idle for at least 2 minutes.
• Using a diagnostic tool, check the gearbox oil temperature.
• Check the final gearbox fill with tool [1], observing the gearbox oil temperature and engine speed given in the table below.

Automatic gearbox oil level check (at 700 rpm ± 50)

Gearbox oil temperature	Value shown on oil dipstick [1]
50 'C	2 à 4
80 'C	5 à 7

The transmission oil level must not be checked in emergency operation mode.

• Check the final gearbox fill again with tool [1], observing the gearbox oil temperature and engine speed given in the table above.
• Correct the level if necessary, then check it again.

If work has been carried out on the transmission oil cooling system, add an additional 0.125 litres of oil.

• Disconnect the diagnostic tool.

• Refit the cap (1) and use a new safety pin (4).

Make sure the safety pin (4) clicks into the cap (1).

• Check for leaks with the engine running.
