Automatic transmission fluid capacity & service interval

Porsche 944 (EU) automatic transmission fluid capacity ranges from 2,8 to 6,5 liters. The data covers 1 configuration.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications

  • Use: Normal
  • Capacity 6,5 liter (Dry fill)
  • Capacity 2,8 liter (Service fill)
  • Code: 4/1

Additional Notes

  • The Porsche 944 (EU) automatic transaxle carries a dry fill capacity of 6.5 liters, a figure that reflects the total fluid volume required when filling a completely drained or rebuilt unit where the torque converter and all internal passages hold no residual fluid.
  • The service fill capacity of 2.8 liters is the volume associated with a routine fluid change, where a portion of the fluid remains trapped in the torque converter and valve body after draining, leaving only a partial refill necessary to restore proper operating level.
  • The gap between the 2.8-liter service fill and the 6.5-liter dry fill indicates that approximately 3.7 liters of fluid are retained within the transaxle assembly during a standard drain, which is a common characteristic of automatic transmissions without a dedicated converter drain plug.
  • The specifications apply under normal use conditions, meaning the listed capacities correspond to standard operating environments rather than severe-duty or high-stress driving cycles.
  • The transaxle layout noted in the specifications refers to a rear-mounted combined transmission and differential unit, a configuration that influences fluid capacity figures differently than a conventional front-mounted automatic gearbox.
