ENGINE OIL
The New Holland 8340 tractor's oil capacity of 22.1 quarts (20.9 liters) denotes a significant oil reservoir, enhancing engine lubrication and thermal management for improved longevity. Optimal oil maintenance is critical; regular monitoring of oil levels and quality can prevent potential engine wear and failure. This capacity is advantageous for extended operating hours, particularly in agricultural or commercial settings, yet also necessitates careful monitoring to avoid overfilling, which can lead to increased crankcase pressure and potential seal failure.

TRANSMISSIONS OVERVIEW
The New Holland 8340 features a 12-speed synchronized and a 16-speed four-speed power shift transmission, providing versatility in various field conditions. The advantages of this design include smooth shifting and enhanced power management, allowing for efficient operation in both high-torque and high-speed scenarios. However, the complexity of the transmission may present challenges in maintenance and serviceability, requiring specialized knowledge and tools for optimal long-term performance.

TRANSMISSION 1
The New Holland 8340 features a SynchroShift transmission with 12 synchronized gears (4 gears across 3 ranges: low, medium, and high), enhancing ease of operation during gear changes. A notable advantage is the synchronized shuttle shifting, which allows for seamless direction changes without engaging the clutch; however, transitioning between low and other ranges requires the tractor to be at a complete stop, potentially limiting operational efficiency in certain scenarios. Overall, the design ensures smooth operation in various field tasks, making it suitable for agricultural applications but may present challenges in situations requiring quick range adjustments.
| Transmission | SynchroShift |
| Type | synchronized |
| Gears | 12 forward and reverse |
| Clutch | dry disc |
| Description | Four gears (1-4) in three ranges (L/M/H) with right-hand shuttle lever. Gear shifts are synchronized. Shifts between medium and high ranges are synchronized, but the tractor should be stopped to shift to or from low range. Sychronized shuttle shifting. The 12-speed SynchroShift was standard on the 8340 SL |
SPEEDS 1
| Description | With 16.9-38 rear tires |
TRANSMISSION 2
The New Holland 8340 features an ElectroShift/Pulse Command transmission with 16 forward and reverse power shift capabilities, providing versatility for various tasks. The use of a wet disc clutch enhances durability and reduces maintenance frequency, while the push-button shifting system offers user-friendly operation, minimizing the need for clutch engagement. However, operators should be cautious with range shifting, as improper use can lead to increased wear on the clutch components, particularly under heavy load conditions.
| Transmission | ElectroShift/Pulse Command |
| Type | four-speed power shift |
| Gears | 16 forward and reverse |
| Clutch | wet disc |
| Oil capacity | 64qts / 60.6L |
| Description | Four power shift gears arranged in two synchronized ratio groups (1-4 and 5-8). Two synchronized ranges (low/high) and right-hand shuttle. Clutch must be used to shift range or move between the lower (1-4) and higher (5-8) gear ratio groups. Push-button power shifting between the four gears in a ratio group. Push-button de-clutching on the shuttle lever allow shifting without the foot clutch. The 16 power shift was standard on the 8340 SLE |

MECHANICAL
The New Holland 8340 tractor offers a versatile 4x2 or optional 4x4 MFWD configuration, enhancing traction under various field conditions. Its inboard planetary final drives provide efficient torque transfer, while the electro-hydraulic differential lock enhances off-road capability by preventing wheel slip. The optional Comfort Command Cab with air-conditioning supports extended operator comfort, making it suitable for prolonged use in diverse agricultural tasks.
