Type	Specifications
MX-5 / Miata 2.0 (118 kW) (2010-2015)	Use: Normal Capacity 7,4 liter Code: SJ6A-EL 6/1
MX-5 / Miata 2.0 (118 kW) (2005-2010)	Use: Normal Capacity 7,4 liter Code: SJ6A-EL 6/1

The automatic transmission fluid capacity for the Mazda MX-5 / Miata NC with the 2.0 (118 kW) engine is 7.4 liters across both the 2005-2010 and 2010-2015 model year spans.
A capacity of 7.4 liters is consistent with a total system fill, accounting for fluid held within the torque converter, valve body, and transmission pan rather than a partial drain-and-fill service quantity.
Both model year configurations carry identical 7.4-liter capacities under normal use conditions, meaning the specification applies to standard operating environments rather than severe or high-stress driving cycles.
