Kia Amanti, GH (USA / CAN)

Automatic transmission fluid capacity & service interval

Kia Amanti, GH (USA / CAN) requires automatic transmission fluid with a capacity range of 8,5 to 10,9 liters. Service intervals include checks at 15000 miles or 12 to 15 months, and fluid changes at 30000 to 105000 miles or 30 to 105 months. The data covers 4 configurations.

Additional Notes

  • The Kia Amanti automatic transaxle fluid capacity differs notably between the two engine variants covered in the specifications. The 3.5-liter engine carries 8.5 liters, while the 3.8-liter engine requires 10.9 liters, a difference of 2.4 liters that reflects the larger transmission assembly paired with the bigger engine.
  • A capacity figure of 10.9 liters for the 3.8-liter transaxle is a total fill volume, meaning it represents the full fluid quantity the unit holds rather than a partial drain-and-refill service amount, which is typically lower in routine maintenance.
  • Both the 3.5-liter and 3.8-liter configurations share the same fluid check interval of 15,000 miles, though the 3.5-liter pairs that with a 15-month time limit under normal use, while the 3.8-liter under normal use pairs the same mileage interval with a shorter 12-month time limit.
  • Under normal use conditions, both engine variants specify a fluid change interval of 105,000 miles. The 3.5-liter (2003-2006) sets a corresponding time limit of 105 months, whereas the 3.8-liter (2007-2009) sets a shorter 84-month time limit despite the identical mileage figure.
  • Under severe use conditions, both the 3.5-liter and 3.8-liter variants align on a fluid change interval of 30,000 miles or 30 months, representing a reduction to roughly one-third of the normal-use mileage interval.
  • The severe-use check interval for the 3.8-liter transaxle is listed at 15,000 miles and 15 months, which matches the normal-use check interval for the same engine, indicating the check schedule does not tighten under severe conditions for that variant.
