Mazda 6, GG/GY (EU)

Automatic transmission fluid capacity & service interval

Mazda 6, GG/GY (EU) automatic transmission fluid capacity ranges from 3 to 8,3 liters. Service intervals include 20000 km/12 months, 40000 km/24 months, and 60000 km/36 months. The data covers 4 configurations.

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

Additional Notes

  • The Mazda 6 GG/GY (EU) 2.3 S-VT carries two distinct capacity figures for its automatic transaxle: a dry fill of 8.15 liters and a service fill of 3 liters. The dry fill represents the total fluid volume required when the transmission is completely empty, such as after a full overhaul or replacement, while the service fill reflects the smaller volume needed during a routine fluid change where residual fluid remains in the torque converter and passages.
  • The 2.0 S-VT (2005-2007) carries a transaxle capacity of 8.14 liters, which is notably higher than the 7.2-liter figure listed for the 2.0 non-S-VT (2002-2005). Since both are automatic transaxles, the difference likely reflects a revised unit introduced alongside the S-VT variable valve timing system in the mid-cycle update.
  • The 2.3 S-VT AWD variant holds the largest single-figure transaxle capacity in the lineup at 8.3 liters, slightly exceeding the 8.15-liter dry fill of the front-wheel-drive 2.3 S-VT. The AWD configuration adds mechanical complexity that accounts for the marginally greater fluid volume.
  • Check intervals across the four configurations span a wide range. The 2.0 S-VT (2005-2007) carries the shortest interval at 20,000 km or 12 months under normal use, while both the 2.0 (2002-2005) and the 2.3 S-VT AWD share the longest interval at 60,000 km or 36 months. The 2.3 S-VT sits between at 40,000 km or 24 months.
  • All four configurations are specified under normal use conditions. No severe-use intervals appear in the specifications for any of the listed engine and drivetrain combinations.
  • The 2.0 engine in the 2002-2005 period is associated with a 7.2-liter transaxle capacity and a 60,000 km check interval, whereas the later 2.0 S-VT covering 2005-2007 pairs a larger 8.14-liter capacity with a significantly shorter 20,000 km interval, indicating a meaningfully different service schedule despite sharing the same displacement.
