Additional Notes

  • The Vauxhall Astra H TwinTop carries two distinct transmission types across its engine range: a semi-automatic transaxle on the 1.6 16V and a conventional automatic transaxle on the 1.8, each with its own fluid capacity figure.
  • The 1.6 16V semi-automatic transaxle holds 1.6 liters of automatic transmission fluid, a relatively modest fill volume consistent with the compact nature of semi-automatic units that share mechanical components with manual gearboxes.
  • The 1.8 automatic transaxle holds 4 liters, a notably larger capacity that reflects the additional fluid volume required by a conventional automatic transmission to supply hydraulic pressure for gear selection and torque converter operation.
  • On the 1.6 16V, the service action specified under normal use conditions is a fluid check at intervals of 12 months or 30,000 km, whichever comes first, rather than a full fluid change.
  • The 1.8 automatic transaxle carries a fluid change interval of 60,000 km or 48 months under normal use conditions, meaning the fluid is replaced rather than simply inspected at each service point.
  • The 1.6 16V entry covering 2006-2007 lists only a 1.6-liter capacity with no associated service interval, while the broader 2006-2010 entry for the same engine adds the 12-month/30,000 km check interval alongside the same capacity figure.
  • Both the 1.6 16V and the 1.8 appear with a discrete 2010-2010 entry alongside their wider year-range entries, each carrying identical capacity and interval specifications to the corresponding broader entry for that engine variant.
