Case - IH CT

Manual transmission fluid capacity & service interval

Case IH CT manual transmission fluid capacity is 15 liters. Service intervals occur every 400 hours or 12 months. The data covers 4 configurations.

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

Additional Notes

  • The Case IH CT series manual transmission fluid specifications cover the CT5050, CT5060, CT5070, and CT5080 models across the 2000-2007 production range.
  • Each of the four CT models carries a transaxle manual configuration, meaning the transmission and drive axle share a single integrated housing that holds a combined fluid volume.
  • A 15-liter capacity is specified uniformly across all four models, which is a relatively substantial fill volume consistent with a transaxle unit rather than a standalone gearbox.
  • The 15-liter figure represents a service fill capacity, reflecting the amount of fluid required during a standard drain-and-refill service interval.
  • The change interval is set at 400 hours or 12 months under normal use conditions, meaning whichever threshold is reached first would trigger a fluid change.
  • The dual-trigger interval structure of 400 hours and 12 months accounts for machines that accumulate operating hours slowly, ensuring a calendar-based change still occurs within a reasonable timeframe regardless of usage intensity.
  • The normal use condition tied to the 400-hour/12-month interval applies identically to all four CT models, with no variation in service frequency across the CT5050, CT5060, CT5070, or CT5080.
