Additional Notes
- The Opel Senator B, V88 automatic transmission fluid capacity splits into two distinct values across the engine lineup: 5.5 liters for the 2.5i and 3.0i, and 2.6 liters for the 2.6i and 3.0i 24V.
- A 5.5-liter fill figure is characteristic of a total system capacity, accounting for fluid held within the torque converter, valve body, and transmission pan combined, rather than a simple pan-drain service quantity.
- The 2.6-liter figure associated with the 2.6i and 3.0i 24V represents a partial service fill, consistent with a drain-and-refill procedure that does not evacuate the torque converter.
- The Senator 2.5i carries a 36-month change interval under normal use conditions, paired with the 5.5-liter capacity.
- The Senator 3.0i shares both the 5.5-liter capacity and the 36-month change interval with the 2.5i, despite being a larger displacement engine.
- The Senator 2.6i, introduced for the 1990-1993 period, carries a 48-month change interval under normal use conditions alongside the 2.6-liter service fill.
- The Senator 3.0i 24V, available from 1989-1993, also specifies a 48-month change interval with the 2.6-liter capacity, aligning with the 2.6i rather than the standard 3.0i in both respects.
- The 12-month difference in change intervals between the two capacity groups means the 2.5i and 3.0i transmissions reach a fluid change cycle one year sooner than the 2.6i and 3.0i 24V under equivalent normal-use conditions.
