Kia K5, DL3 (USA / CAN)

Automatic transmission fluid capacity & service interval

Kia K5, DL3 (USA / CAN) automatic transmission fluid capacity ranges from 3,3 to 6,5 liters. Service intervals include checking at 32000 miles or 48 months, and changing at 56000, 60000, or 64000 miles. The data covers 8 configurations.

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

Additional Notes

  • All four configurations using a conventional automatic transmission — the 1.6 T-GDI, 1.6 T-GDI AWD, 2.5 GDI, and 2.5 GDI AWD — share a 6.5-liter fluid capacity. A capacity at this level typically reflects a full service fill, accounting for the torque converter, valve body, and transmission pan combined.
  • The 2.5 T-GDI uses a semi-automatic transaxle rather than a conventional automatic transmission. A transaxle integrates the transmission and differential into a single housing, which is why the fluid capacity of 3.3–3.4 liters is notably lower than the 6.5 liters specified for the automatic units.
  • The 3.3–3.4 liter capacity range on the 2.5 T-GDI transaxle reflects a tolerance band rather than a fixed fill volume. Slight variation in the actual fluid level at the point of service accounts for the spread between the lower and upper figures.
  • The Kia K5 1.6 T-GDI and 1.6 T-GDI AWD, covering model years 2020-2024, carry a severe-use change interval of 56,000 miles for automatic transmission fluid. Severe-use classifications typically apply when the vehicle is regularly subjected to conditions such as towing, stop-and-go traffic, or extreme temperatures.
  • The 2.5 GDI and 2.5 GDI AWD configurations, starting from 2025, specify a 60,000-mile change interval under severe use. Compared to the 56,000-mile interval on the 1.6 T-GDI variants, the 4,000-mile difference reflects a distinct service schedule tied to the engine and transmission pairing rather than a universal interval across all K5 automatic transmission applications.
  • The 2.5 T-GDI transaxle specifications include a fluid check interval of 32,000 miles or 48 months under both normal and severe use conditions. A periodic check interval, separate from a change interval, is used to monitor fluid condition and level without necessarily requiring a full drain and refill at that mileage point.
  • Under severe use, the 2.5 T-GDI transaxle adds a 64,000-mile fluid change interval on top of the 32,000-mile check schedule. Under normal use, no change interval is listed — only the 32,000-mile or 48-month check applies. The distinction between the two use conditions therefore determines whether a fluid change is required at all within the specified service framework.
  • The 2.5 T-GDI transaxle specifications are identical across the 2020-2024 and 2025 model year groups. Both the capacity range of 3.3–3.4 liters and the service intervals — 32,000 miles or 48 months for a check, and 64,000 miles for a change under severe use — remain unchanged between the two production periods.
