Additional Notes
- The Kenworth Off Highway 963 automatic transmission carries a fluid capacity of 68 liters, and the specification notes this figure excludes external circuits, meaning the total system volume in a full overhaul or circuit-inclusive service would exceed that amount.
- The 68-liter figure represents a service fill measurement rather than a complete system volume, a distinction that matters when ordering fluid quantities for maintenance work on the 963 transmission.
- The change interval for the 963 automatic transmission is set at 1,200 hours, a time-in-operation measure rather than a distance-based interval, which is standard practice for off-highway equipment that accumulates engine hours rather than road miles.
- The use condition listed for the 963 is flexible with fluid analysis, meaning the 1,200-hour interval is not a fixed hard limit but is instead subject to adjustment based on the results of periodic fluid sampling and laboratory analysis.
