TRANSMISSION
The International Harvester 5488 features a Synchro Tri-Six partial power shift transmission, providing seamless on-the-move gear changes across 18 forward and 6 reverse speeds, essential for efficient field operations. The 174-quart oil capacity supports robust lubrication and cooling, which is critical for prolonged heavy-duty use. While the clutch-free powershifting enhances productivity, operators must be familiar with synchronized shifting techniques for optimal performance in varying terrain scenarios.
| Transmission | Synchro Tri-Six (STS) |
| Type | partial power shift |
| Gears | 18 forward and 6 reverse |
| Oil capacity | 174qts / 164.7L |
| Description | Left lever selects gear, right lever selects high, medium, low, or reverse range. Clutch-free on-the-move powershifting in gear pairs 1/2, 3/4, and 5/6. Synchronized on-the-move shifting (with the clutch) between pairs |
SPEEDS
