Additional Notes

  • The BMW 6 Series E24 (USA) manual transmission fluid capacity spans a range from 1.1 liters to 1.6 liters across the model lineup, reflecting differences in Getrag gearbox sizes used in different variants.
  • The 630 CSi (1976-1979) carries a manual transmission fluid capacity of 1.1 liters under normal use conditions, which is the smallest fill volume listed across the E24 range.
  • The 633 CSi (1979-1984) with a Getrag manual transmission is listed with two separate capacity figures: 1.1 liters and 1.6 liters, both under normal use conditions, indicating that two distinct Getrag gearbox variants were fitted to the same model during that production period.
  • The 635 CSi (1987-1989) Getrag manual transmission holds 1.6 liters of fluid, the largest capacity in the E24 lineup, and service intervals are governed by the on-board maintenance system rather than a fixed mileage or time schedule.
  • The M6 (1987-1989) is listed with two Getrag manual transmission variants distinguished by plate color. The green plate version specifies a capacity of 1.25 liters and carries a notation indicating the figure applies without a dual mass flywheel. The red plate version also specifies 1.25 liters, with no such conditional notation.
  • Both M6 (1987-1989) Getrag variants, regardless of plate color, share the same 1.25-liter fluid capacity and are both serviced under the flexible interval tied to the on-board maintenance system.
  • The on-board maintenance system, referenced for the 635 CSi and M6 (1987-1989) variants, calculates service intervals dynamically based on operating conditions rather than applying a single fixed schedule, which is what the flexible use designation reflects in the specifications.
  • The 630 CSi and the two 633 CSi configurations are the only E24 variants in the specifications assigned a normal use condition, meaning service intervals for those models follow a standard fixed schedule rather than a condition-based system.
