The ZF TraXon service manual is a technical guide for maintaining, diagnosing, and repairing ZF's 12- and 16-speed automated transmissions (e.g., 12 TX and 16 TX series). Official documentation is typically tiered into "Repair Levels," with Level 1 and 2 manuals covering routine maintenance and external component replacement, while higher levels (Stage 3) cover complete dismantling. Core Service Procedures
Based on official repair instructions, a standard service includes:
Maintenance & Lubrication: Uses TE-ML 02 grade oil. Oil capacities vary by model (e.g., 12.5L to 24.5L depending on the presence of an Intarder).
Clutch Actuation (ConAct): Procedures for bleeding the ConAct pneumatic release cylinder and checking the optimal release position.
Module Replacement: Instructions for removing and installing critical external modules, including: Transmission control unit (ECU) and valve block. Selector actuator and speed sensors. Adapter plates and Power Take-Off (PTO) covers.
Diagnosis: Using the ZF Testman diagnostic tool to interpret fault codes, such as gate selection faults, and perform gearset programming. Accessing Manuals & Documentation Hino 700 ZF TraXon Transmission Manual | PDF - Scribd

The manual begins with critical warnings: depressurizing the air system (minimum 2.5 bar residual pressure can cause unexpected shifts) and the necessity of ZF-approved diagnostic software (e.g., ZF Testman or PC-based ZF Diagnos). It lists specialized tools like the clutch centering mandrel (part no. 0735 300 003) and the gear position locking pins.
The ZF TraXon service manual is a comprehensive technical reference—not a simple owner’s guide. It enables correct diagnostics, safe repairs, and long-term durability of one of the most advanced commercial vehicle transmissions in the market. For professional use, always obtain the official version through ZF’s authorized distribution channels.

The ZF TraXon is a 12-speed automated manual transmission (AMT) designed for heavy-duty commercial vehicles, buses, and special-purpose applications. Serving as the successor to the widely used AS Tronic series, the TraXon architecture features a higher torque capacity (up to 3,400 Nm in certain variants) and improved efficiency through optimized oil management and lighter-weight components.
The system is defined by its modular design, allowing for seamless integration with hybrid powertrains (TraXon Hybrid) and automated driving systems.
