Fluid - ASMT: Description and Operation

Transmission

Oil Type/Oil Quantity/Change Intervals







Since the final drive is located in a separate housing, the Porsche Doppelkupplung (PDK) transmission in the Panamera models manages with one oil chamber.

Pentosin Gear Oil FFL3 is used in this chamber. The oil chamber has a filling capacity of 8.5 liters, the oil must be changed every 60,000 miles (90,000 km) or every 6 years.

Viewed in the direction of travel, the oil inspection plug is located at the rear, in the middle, at the end of the transmission between the exhaust pipes (arrow). You can add oil/check the oil level in the same way that you do for the PDK in sports cars. The correct oil level is important for proper operation and long life of the transmission.

The following prerequisites must be met in order to check or correct the oil level:
- Engine must be idling
- Vehicle must be horizontal in both longitudinal and transverse axis
- Oil temperature between 86 °F. and 104 °F. (30 °C. and 40 °C.)
- Selector-lever position "P"
- Clutch cooling volume flow must be switched off (using PIWIS Tester in Oil fill mode)
- Retain the described states for approx. 1 minute to allow the oil to settle
- Open the screw plug on the oil overflow bore (see arrow) and collect the emerging oil until only drops of oil are emerging
- Once there is no more oil emerging, top up the clutch fluid until oil escapes from the oil overflow bore
- To avoid damaging the clutches, the procedure must be completed within 5 minutes (PIWIS Tester exits Oil fill mode automatically after 5 minutes)
