Additional Notes

  • The GM Ranger B (II) manual transmission holds 1.1 liters of fluid across all listed variants, covering the 1700, 1700S, 1900, 2500, 2500 GTS, and 2800 GTS engine configurations from 1972-1978.
  • A capacity figure of 1.1 liters is consistent with compact manual gearboxes of the era, reflecting a service fill volume rather than a full overhaul or dry-fill quantity, which would typically be higher.
  • The check interval of 10,000 km or 6 months, whichever comes first, applies under normal use conditions across every listed variant. The dual-trigger format means the time-based threshold of 6 months can prompt a check even before the distance figure is reached.
  • No variation in manual transmission fluid capacity or check interval exists between the six listed variants, despite differences in engine displacement ranging from 1700 cc to 2800 cc.
  • The 2500 GTS was produced from 1972-1974, while the 2800 GTS entered the lineup in 1974-1978, representing a displacement increase in the GTS trim line within the same generation.
  • The 1700 and 1700S share identical transmission fluid specifications, with the S designation indicating a variant of the base 1700 engine rather than a mechanically distinct drivetrain requiring different service parameters.
