Kia Carnival, KA4 (USA / CAN)

Automatic transmission fluid capacity & service interval

Kia Carnival, KA4 (USA / CAN) uses automatic transmission fluid with a capacity range of 6 to 7 liters. The service interval for fluid changes is 56000 miles. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

  • Use: Severe
  • Capacity 7 liter
  • Change 56000 miles
  • Code: A8LF1 8/1

Additional Notes

  • The Carnival 3.5 GDi carries a 7-liter automatic transaxle fluid capacity, while the 1.6 T-GDI Hybrid requires 6 liters, a difference of one full liter between the two powertrains.
  • Both configurations share an identical service interval of 56,000 miles, though both are designated for severe use conditions rather than normal driving cycles.
  • A severe use designation typically reflects operating conditions such as frequent towing, stop-and-go traffic, extreme temperatures, or short-trip driving, all of which accelerate fluid degradation relative to normal use.
  • The Kia Carnival KA4 1.6 T-GDI Hybrid pairs a hybrid drivetrain with an automatic transaxle, and the 6-liter capacity reflects the fluid volume specific to that transaxle assembly rather than a conventional torque-converter unit.
  • At 56,000 miles under severe conditions, both the 3.5 GDi and the 1.6 T-GDI Hybrid reach their fluid change interval at the same mileage point, despite the meaningful difference in their respective fluid volumes.
