Case Articulated haulers
Automatic transmission fluid capacity & service interval
Case Articulated haulers use automatic transmission fluid with a capacity range of 19 to 38 liters. Service intervals include checks at 100 hours and changes at 100 or 1000 hours. The data covers 7 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Case 325 with Cummins 6CTAA8.3 engine carries a powershift transmission fluid capacity of 23 liters, while the 330 with Cummins QSM11 holds 19 liters, representing a notable difference between two models sharing the same 1000-hour normal change interval.
- The 340 with Case 13F3B engine holds 38 liters in the powershift transmission, the largest fixed capacity across all configurations listed, and follows the same 100-hour check and 1000-hour change schedule under normal use conditions.
- The 335 with Case 13F3B engine carries a capacity range of 35.5 to 38 liters rather than a single fixed value, which typically reflects variability introduced by factors such as torque converter drain-back or fill method during service.
- Both the 325 and 330 share an initial service change interval of 100 hours, meaning the first fluid change occurs far earlier than the 1000-hour normal interval, a practice common in powershift transmissions to remove break-in contaminants and fine metallic particles generated during initial component wear-in.
- The 340 with Case 13F3B engine also specifies an initial service change at 100 hours with a capacity of 38 liters, aligning with the same early-change practice seen on the smaller-displacement Cummins-powered models.
- Under normal use conditions, the 325 and 330 both require a fluid level check every 100 hours, an interval ten times more frequent than the full change interval of 1000 hours, indicating that monitoring fluid level between changes is treated as a routine maintenance step independent of the drain-and-fill cycle.
- The 335 with Case 13F3B engine has no check interval or change interval listed under normal use conditions, only a capacity range, which distinguishes the service data available for that model from the more detailed interval specifications present for the 325, 330, and 340.
