Additional Notes

  • The Opel Astra L manual transaxle capacity varies by engine, with the 1.2 Turbo variants specifying a range of 1.7-1.8 liters, while the 1.5 Diesel specifies a fixed 1.9 liters.
  • A capacity expressed as a range, such as the 1.7-1.8 liter figure for the 1.2 Turbo transaxles, typically reflects a fill-to-level procedure rather than a fixed measured quantity, meaning the correct fill point is determined by the overflow or check port rather than a precise volume.
  • The 1.5 Diesel (96 kW, YHZ) transaxle capacity of 1.9 liters is the highest among the three listed configurations, sitting above the upper bound of the 1.2 Turbo range.
  • All three configurations share the same use condition classification of normal, meaning the listed capacities apply under standard operating conditions rather than severe or first-change-only scenarios.
  • Both 1.2 Turbo variants, the 81 kW (HNP) and the 96 kW (HNS), share an identical capacity specification of 1.7-1.8 liters despite differing in power output, indicating the same manual transaxle unit is used across both power levels.
  • All three entries are classified as transaxle units, meaning the transmission and final drive share a common fluid sump rather than being serviced as separate assemblies.
