Transmission Fluid, Draining and Filling

Special tools and workshop equipment required

• Used Oil Collection and Extraction Unit -SMN372500-
• Pressurized Gearbox Oil Filler Kit -VAS6617-
• Torx Socket - T60 -T40087-
• Protective Eyewear

Draining

  Note

• The S tronic transmission does not have any drain plug for the transmission fluid system. To drain the transmission fluid, the transmission fluid pump must be removed.
• General repair instructions. Refer to → Chapter "Repair Information".
• Guidelines for clean working conditions. Refer to → Chapter "Guidelines for Clean Working Conditions".

• Transmission fluid temperature at approximately 20 ℃ (68 ºF) (room temperature).
• Move vehicle onto a four-pillar workshop hoist or over a work pit so that it is absolutely horizontal.

- Remove the rear noise insulation. Refer to → Body Exterior; Rep. Gr.66; Noise Insulation; Noise Insulation, Removing and Installing.

- Place the Used Oil Collection and Extraction Unit -SMN372500- underneath.

  WARNING

Danger of eye injury.

Wear protective eyewear.

  Caution

Risk of electrical corrosion.

• There must not be any transmission fluid (MTF) in the connector area.
• Do NOT disconnect the connector -2-.

  Note

When removing the oil pump, the transmission drains abruptly.

- Remove the bolts -arrows- and remove the oil pump -1- and secure with wire so that it does not fall.

- Drain the transmission fluid (MTF).

  Caution

Risk of damaging the transmission.

Without any or with too little manual transmission fluid (MTF) inside the transmission:

• Do not start the engine.
• Do not tow the vehicle.

  Note

• Worn out manual transmission fluid (MTF) can stain the transmission fluid filter housing.
• Clean debris from the sealing surfaces.

- Install the oil pump. Refer to → Chapter "Transmission Fluid Pump, Removing and Installing".

Filling

  WARNING

Danger of eye injury.

Wear protective eyewear.

  Caution

Risk of damaging the transmission.

• Only use the specified transmission fluid (MTF) in the parts list for the dual-clutch transmission 0CJ, 0CK, 0CL.
• Using other fluids can cause malfunctions or transmission failure.
• Note the allocation. Refer to the Parts Catalog.
• The Pressurized Gearbox Oil Filler Kit -VAS6617- must be clean and ATF must not be mixed with another fluid! Apply transmission fluid (MTF) to the hand pump if necessary.

- Remove the plug -arrow- for the right inspection and fill hole on the transmission housing with the Torx Socket - T60 -T40087-.

- Slowly fill transmission fluid (MTF) using Pressurized Gearbox Oil Filler Kit -VAS6617-.

• Transmission fluid (MTF) specification. Refer to the Parts Catalog.

- Repeat the procedure gradually every 15 seconds, until the transmission fluid is 2 mm under the lower edge of the inspection and fill hole.

  Note

It is important to follow the waiting period to make sure the various oil spaces in the transmission are filled equally.

- Tighten the plug.

Further installation is performed in reverse order of the removal.
