Additional Notes

  • The Opel Mokka X J13 automatic transaxle carries a dry fill capacity of 8 to 8.5 liters, a figure that reflects the total fluid volume required when filling a completely drained or newly assembled unit where no residual fluid remains in the torque converter or valve body.
  • Service fill capacity is listed at 4 to 6 liters across all five configurations, representing the partial volume exchanged during a routine fluid service where a portion of the fluid remains trapped in the transmission circuit.
  • The gap between the dry fill and service fill values means a standard service interval replaces roughly half to three-quarters of the total fluid volume at most, leaving a significant portion of aged fluid in the system.
  • All five configurations share an identical check interval of 12 months or 30,000 km under normal use conditions, applying equally to the petrol and diesel variants across the 2016-2019 period.
  • The 1.4 DI Turbo at 112 kW and the 1.4 Turbo at 103 kW both use the same transaxle automatic fluid specifications despite differing in output, with dry fill at 8 to 8.5 liters and service fill at 4 to 6 liters.
  • The 1.6 CDTI at 100 kW, a diesel engine, shares the same automatic transaxle fluid capacities and check interval as the petrol-engined variants, indicating a common transmission unit across the powertrain range.
  • The 1.4 Turbo 103 kW and the 1.6 CDTI 100 kW each appear across two overlapping year bands, 2016-2018 and 2018-2019, with no change in fluid capacity or service interval between the two entries for either engine.
