Case - IH CS

Manual transmission fluid capacity & service interval

Case IH CS manual transmission fluid capacity ranges from 33 to 34 liters. Service intervals include checks every 500 hours and changes every 1000 hours or 12 months. The data covers 3 configurations.

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

Additional Notes

  • The Case-IH CS 78 manual transaxle carries a fluid capacity of 33 liters, while the CS 86 and CS 94 each hold 34 liters, reflecting a modest but measurable difference tied to the larger transaxle housings in the higher model variants.
  • All three configurations share an identical check interval of 500 hours under normal use conditions, meaning fluid level verification is due at the halfway point before a full drain and refill is required.
  • The change interval across the CS 78, CS 86, and CS 94 is set at 1000 hours or 12 months, whichever comes first under normal use, applying a dual threshold that accounts for both operational time and calendar aging of the fluid.
  • The 33- and 34-liter capacities listed for the manual transaxle represent service fill volumes, which in agricultural equipment of this class typically reflect the total system capacity rather than a partial drain figure.
  • All specifications covering the 1997-2004 model years are designated for normal use conditions, meaning the stated check and change intervals apply to standard operating environments rather than elevated-stress or severe-duty cycles.
