TRANSMISSIONS OVERVIEW
The J.I. Case 2594 features a 12-speed three-speed power shift or an optional 24-speed four-speed power shift transmission, providing versatile gear selection for varied field and road conditions. This flexibility enhances operational efficiency, allowing for better torque management and fuel economy during tasks such as plowing or hauling. However, the complexity of the power shift system may require additional maintenance and operator training to ensure optimal performance.
| Description | 12-speed three-speed power shift/24-speed four-speed power shift |
TRANSMISSION 1
The J.I. Case 2594 tractor features a robust three-speed power shift transmission that offers 12 forward and 3 reverse gears, enabling versatile performance across various applications. The oil capacity of 128 quarts (121.1L) ensures efficient hydraulic and transmission function, although attention to fluid levels is crucial for optimal operation. A notable limitation is that reverse is inoperative in the fourth range, which may pose challenges during maneuvering in tight spaces or when performing tasks requiring repeated directional changes.

TRANSMISSION 2
The J.I. Case 2594 tractor features a four-speed power shift transmission with 24 forward and 3 reverse gears, enhancing versatility in various field operations. Its 128-quart oil capacity is advantageous for efficient hydraulic performance, ensuring optimal cooling and lubrication under heavy use. However, operators should note that reverse functionality is unavailable in the fourth range, potentially limiting maneuverability in high-speed scenarios.
| Type | four-speed power shift |
| Gears | 24 forward and 3 reverse |
| Oil capacity | 128qts / 121.1L |
| Description | Six power shift gears (1-6), plus reverse, in four ranges (1-4). Reverse does not work in fourth range |
