Mazda CX-7, ER (EU)

Automatic transmission fluid capacity & service interval

Mazda CX-7, ER (EU) automatic transmission fluid capacity ranges from 3 to 7 liters. The service interval is 90000 km or 72 months. The data covers 2 configurations.

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

TypeSpecifications
CX-7 2.5 (2009-2012)
  • Use: Normal
  • Capacity 5 liter (Dry fill)
  • Capacity 3 liter (Service fill)
  • Code: FS5A-EL 5/1
CX-7 2.3 DISI Turbo automatic (2007-2012)
  • Use: Normal
  • Capacity 7 liter
  • Change 90000 km/ 72 months
  • Code: AW6AX-EL 6/1

Additional Notes

  • The 2.3 DISI Turbo automatic transaxle carries a fluid capacity of 7 liters, which represents a notably higher volume than the 2.5's service fill figure, reflecting the demands of a turbocharged drivetrain on the transmission cooling and lubrication circuit.
  • For the Mazda CX-7 2.3 DISI Turbo automatic, a change interval of 90,000 km or 72 months is specified under normal use conditions, meaning the interval applies to standard driving rather than elevated-stress operation.
  • The 2.5 automatic transaxle lists two distinct capacity values: a dry fill of 5 liters and a service fill of 3 liters. The dry fill reflects the total system volume when the unit is completely empty, such as after a full overhaul or replacement, while the service fill of 3 liters represents the amount drained and replaced during a routine fluid change.
  • The gap between the 2.5's dry fill and service fill capacities indicates that approximately 2 liters of fluid remain in the torque converter and passages during a standard drain procedure, which is a common characteristic of automatic transmissions where a full drain is not achievable without disassembly.
  • No change interval data appears in the 2.5 automatic transaxle row, whereas the 2.3 DISI Turbo row carries a defined 90,000 km or 72-month schedule under normal conditions.
  • The 2.3 DISI Turbo automatic was available across the full 2007-2012 span, while the 2.5 automatic entered the lineup from 2009, resulting in a three-year period where only the turbocharged variant's automatic transmission specifications applied to the CX-7 ER (EU) range.
