  Note

  • The ATF level is checked at the ATF check and fill hole.
  • The ATF level is correct if a small amount of fluid drips out of the inspection and fill opening (this is normal as the fluid expands as it heats up) at an ATF temperature between 35 º and 45 ºC (95 to 113 ºF).

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

  WARNING

Danger of eye injury.

Wear protective eyewear.

- As soon as an ATF temperature of 35 ºC (95 to 113 ºF) is reached, remove the plug -arrow- on the inspection and fill hole or open the plugs.

  Note

An aluminum oil pan is shown.

- If necessary let any excess ATF run out.

  Note

If the ATF starts to drip out of the inspection and fill hole before it reaches 45 ºC (113 ºF), then the ATF level is OK.

- Assemble the vehicle.

If no ATF drips out of the inspection and fill hole before it reaches 45 ºC (113 ºF), fill with ATF:

- Switch off the engine and let the transmission cool down to 35 ºC (95 ºF).

  Caution

Risk of damaging the transmission.

  • Only use the listed replacement ATF 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! Rinse the hand pump with ATF if necessary.

  WARNING

Danger of eye injury.
