* Replace the pan gasket.
* Tighten the new automatic transmission pan bolt with a force of 25 Nm.
4. Filling with new oil:
* Install a funnel into the hole for the automatic transmission dipstick.
* Fill the automatic transmission with the same amount of oil that was drained, approximately 4-5 liters.
5. Checking the oil level:
* Start the engine and warm it up to operating temperature.

* Place the car on a level surface and turn off the engine.
6. Checking the oil level (continued):
* Pull out the automatic transmission dipstick and wipe it.
* Insert the dipstick back into the tube and pull it out again.
* The oil level should be between the “min” and “max” marks on the dipstick.
7. Final control:

* Make sure there are no oil leaks under the car.
* Reset the oil change counter in the automatic transmission electronic control unit (ECU).
Adviсe:
* It is recommended to partially change the automatic transmission oil every 60,000-80,000 km.
* To completely change the oil, you will need special equipment, for example, an automatic transmission oil pump.
* Use only the recommended automatic transmission oil specified in the vehicle’s owner’s manual.
*If the oil is dark in color or smells burnt, a complete oil change may be needed.
