Additional Notes

  • The Skoda 1000/1100MB manual transaxle holds 2.5 liters as a dry fill capacity. A dry fill figure represents the total volume required when filling a completely drained or newly assembled unit, accounting for all internal passages and cavities that hold no residual fluid.
  • The service fill capacity across all listed variants is 2 liters, which is 0.5 liters less than the dry fill. The difference reflects fluid retained within the transaxle during a routine drain, meaning a standard fluid change does not require the full 2.5-liter volume to restore proper operating level.
  • All six variants share an identical three-stage break-in fluid change schedule. The initial service interval is set at 1,000 km, followed by a second change only interval at 2,500 km, after which the normal 20,000 km or 24-month interval applies. The early changes are intended to flush metallic particles generated during the mechanical wear-in period of new or rebuilt components.
  • The normal change interval of 20,000 km carries a concurrent time limit of 24 months. Whichever threshold is reached first would trigger a fluid change, meaning low-mileage use does not exempt the transaxle from periodic fluid renewal.
  • The 1000MB with engine code 990 covers the 1964-1966 period, while the 1000MB with engine code 721 spans 1966-1969. Both share identical transaxle fluid capacities and service intervals, indicating no specification change accompanied the engine code transition within the 1000MB sedan line.
  • The 1000MBG, engine code 710, produced from 1966-1968, carries the same 2.5-liter dry and 2-liter service fill figures as the standard 1000MB sedan variants. The MBG designation refers to a wagon body style, and the shared transaxle specifications suggest a common gearbox unit across body variants.
  • The coupe variants, the 1000MBX with engine code 990T from 1966-1968 and the 1100MBX with engine code 723 from 1968-1969, share the same transaxle fluid specifications as the sedan and wagon configurations. The 990T suffix on the coupe engine code distinguishes it from the standard 990 unit used in the sedan.
  • The 1100MB, engine code 715, and the 1100MBX Coupé, engine code 723, both cover the 1968-1969 period. The move from the 1000 to 1100 engine displacement series brought no change to the manual transaxle fluid capacity or service interval specifications.
