ERF EC6 automatic transmission fluid capacity is 27 liters. Service intervals include normal use. The data covers 2 configurations.

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

Type	Specifications
EC 6.22 (4x2/6x2) (1996-2002)	Use: Normal Capacity 27 liter Code: Allison MD 3560P 5/1
EC 6.23 (4x2/6x2) (1996-2002)	Use: Normal Capacity 27 liter Code: Allison MD 3560P 5/1

The ERF EC6 automatic transmission fluid capacity is listed at 27 liters across both the EC 6.22 and EC 6.23 variants, covering 4x2 and 6x2 axle configurations from 1996-2002.
A 27-liter automatic transmission capacity is characteristic of a heavy-duty commercial vehicle unit, reflecting the larger fluid volumes required by multi-speed automatic gearboxes designed for truck applications.
The capacity figure of 27 liters applies under normal use conditions, meaning the interval and fill quantity are based on standard operating environments rather than severe-duty cycles.
Both the EC 6.22 and EC 6.23 share an identical 27-liter automatic transmission fluid capacity, indicating no variation in transmission fluid volume between the two engine designations within the 1996-2002 production span.
The 4x2 and 6x2 drivetrain configurations within each variant carry the same 27-liter transmission fluid specification, meaning axle arrangement does not alter the stated capacity for either the EC 6.22 or EC 6.23.
