Additional Notes

  • The Porsche 914 (EU) 914/4 torque converter holds 6 liters of automatic transmission fluid, a figure that reflects the full hydraulic volume required to fill the converter housing rather than a routine drain-and-fill quantity.
  • The 914/4 automatic transaxle carries a separate 2.5-liter fluid capacity, meaning the torque converter and transaxle are serviced as two distinct fluid volumes rather than a single combined fill.
  • A fluid level check interval of 5,000 km applies to the 914/4 automatic transaxle under normal use conditions, indicating a relatively frequent inspection cycle relative to the change interval.
  • The transaxle fluid change interval for the 914/4 under normal use conditions is set at 20,000 km, which is four times the check interval specified for the same component.
  • Both the torque converter and the automatic transaxle specifications for the 914/4 are designated for normal use conditions, with no severe-use interval variant listed for either component across the 1969-1973 model years.
