TRANSMISSION
The J.I. Case 4994 tractor features a full power shift transmission with 12 forward and 2 reverse gears, providing seamless gear changes for enhanced operator control. The electronically-controlled system, operated via a single control lever and inching pedal, requires the tractor to be in motion before selecting higher gears, which can be a challenge for new operators. The oil capacity is 63 quarts, potentially limiting the duration of operation without maintenance, emphasizing the need for regular checks to avoid hydraulic issues.

| Gears | 12 forward and 2 reverse |
| Oil capacity | 63qts / 59.6L 59qts / 55.8L (without PTO) Case Powergard PTF |
| Description | Electronically-controlled Case powershift transmission operated with single control lever and inching pedal. The inching pedal must be depressed to move from park/neutral into first gear. Tractor must be moving in first gear before higher gears can be selected. Gear changes made by pushing control lever into upshift or downshift position. Control lever can be held in upshift/downshift position for multiple gear changes |
