Additional Notes

  • The Vauxhall Senator B, V88 automatic transmission fluid specifications cover four engine variants across the 1987-1993 model range, with capacity figures splitting into two distinct values depending on the engine fitted.
  • The Senator 2.5i and Senator 3.0i share a 5.5-liter automatic transmission fluid capacity. A figure at that level typically reflects a full overhaul or dry fill quantity, accounting for fluid held within the torque converter as well as the transmission pan and passages.
  • The Senator 2.6i and Senator 3.0i 24V each carry a 2.6-liter capacity. A value in that range is more consistent with a service fill, representing the amount drained and replaced during a routine fluid change rather than a complete system evacuation.
  • The 36-month change interval applies under normal use conditions to the Senator 2.5i and Senator 3.0i, both of which also share the 5.5-liter capacity figure.
  • The Senator 2.6i and Senator 3.0i 24V are specified at a 48-month change interval under normal use conditions, which is 12 months longer than the interval assigned to the 2.5i and 3.0i variants.
  • The Senator 2.6i entered the specification range from 1990, making 1990 the starting year for that variant within the 1987-1993 model period, while the Senator 3.0i 24V starts from 1989.
  • The pairing of a longer 48-month interval with the lower 2.6-liter capacity on the Senator 2.6i and 3.0i 24V suggests a different transmission unit is fitted in those variants compared to the engines specifying 5.5 liters and a 36-month interval.
