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

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

The ERF ES6 automatic transmission fluid capacity is listed at 27 liters across both the ES 6.22 and ES 6.23 variants, covering 4x2 and 6x2 axle configurations from 1996-2002.
A 27-liter automatic transmission capacity is characteristic of heavy-duty commercial vehicle transmissions, where larger fluid volumes are necessary to manage heat and lubrication demands under sustained load conditions.
The capacity figure of 27 liters applies under normal use conditions, meaning the interval and fill quantity are based on standard operating circumstances rather than severe-duty cycles.
Both the ES 6.22 and ES 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, with no differentiation in capacity based on axle arrangement.
