Additional Notes

  • The Vauxhall Astra G Classic, T98 manual transaxle holds 1.6 liters of fluid across the 1.4 16V, 1.6 16V, and 1.7 CDTi engine variants for the 2004-2009 model years.
  • A transaxle is a combined transmission and differential unit housed in a single assembly, and the 1.6-liter fill capacity listed here applies to a service fill rather than a full overhaul, which would typically require a higher volume.
  • The check interval for all three variants is set at 12 months or 30,000 km under normal use conditions, whichever comes first.
  • The 30,000 km interval is relatively frequent for a manual transmission fluid check, reflecting a maintenance-oriented schedule rather than a sealed-for-life approach.
  • No variation in fluid capacity exists between the petrol and diesel configurations in the 2004-2009 range, with the 1.7 CDTi sharing the same 1.6-liter transaxle specification as both petrol-engined variants.
