ENGINE DETAIL
The Fiat M135 tractor is powered by a New Holland Genesis turbocharged 6-cylinder diesel engine with a displacement of 7.5L, generating 135hp at a rated RPM of 2200. The high compression ratio of 17.5:1 and torque availability at 1400 RPM enhance its efficiency for heavy-duty tasks, making it ideal for agricultural applications requiring consistent power output. However, the large coolant capacity of 25.4 - 27.5 quarts necessitates regular maintenance to avoid overheating, especially under strenuous conditions.

TRANSMISSIONS OVERVIEW
The Fiat M135 tractor features a sophisticated 23-speed transmission with partially synchronized shifting, allowing for versatile speed management suitable for various field operations. The inclusion of 17-speed and 18-speed partial power shift options offers flexibility for different load conditions, enhancing fuel efficiency and potentially reducing wear on drivetrain components. However, operators may need to adapt to the complexity of the transmission system, which could pose a learning curve in optimizing performance based on specific agricultural tasks.

TRANSMISSION 1
The Fiat M135's partially synchronized Dual Command transmission provides flexibility with 23 forward and 12 reverse gears, enabling smooth gear shifts while in motion using the clutch, although range shifts require stopping. The wet disc clutch offers durability and reduced slippage, enhancing power transfer, while an optional creeper gear can expand speeds to 46 forward and 24 reverse for intensive applications. However, the requirement to stop for range changes may limit operational efficiency in dynamic tasks, making it more suitable for applications that prioritize gear selection over rapid maneuvering.
| Transmission | Dual Command |
| Type | partially synchronized |
| Gears | 23 forward and 12 reverse |
| Clutch | wet disc |
| Oil capacity | 76.8qts / 72.7L |
| Description | Four gears (1-4) in three ranges (A-C) with left-hand shuttle lever and push-button underdrive. Gear shifts may be made on the move with the clutch. The tractor must be stopped to shift range. The forward-reverse shuttle, and the push-button underdrive, may be performed on the move without the clutch. Reverse gears operate in underdrive only. Optional creeper doubles the available speeds to 46 forward and 24 reverse |
TRANSMISSION 2
The Fiat M135 tractor features a 17-speed Range Command transmission with partial power shift, providing enhanced versatility for varying field conditions. Key advantages include the push-button gear shifting for seamless operation and the optional creeper gear, which expands speeds significantly to 30 forward and 12 reverse, optimizing it for precise tasks such as tilling or cultivating. However, the limitation of reverse gears available only in range B may challenge maneuverability in tight spaces, necessitating careful planning during operations.
| Transmission | Range Command |
| Type | partial power shift |
| Gears | 17 forward and 6 reverse |
| Clutch | wet disc |
| Oil capacity | 94.8qts / 89.7L |
| Description | The 17-speed Range Command transmission was available with 2WD. Six gears (1-6) in three ranges (A-C) with left-hand shuttle lever. Push-button gear shifting on the move. To shift ranges, hold up or down gear shift button while pressing range shift button. Reverse is available in range B only. Optional creeper increases available speeds to 30 forward and 12 in reverse |
TRANSMISSION 3
The Fiat M135 tractor's 18-speed Range Command transmission offers a versatile partial power shift system, facilitating smooth gear transitions with push-button controls while on the move. Its wet disc clutch enhances durability and performance under heavy loads. Note that reverse gear is only accessible in range B, which may limit maneuverability in tight spaces; however, an optional creeper gear can improve low-speed capabilities for precision tasks.
