Hydraulic & Lubrication Parameters
| Parameter Item | Details / Standard Value | Remarks |
|---|---|---|
| Main Circuit System Pressure | 16 + 2 bar (1.6 - 1.8 MPa) | Standard oil pressure required for clutch engagement during shifting. |
| Torque Converter Safety Valve Opening Pressure | 8.5 ± 0.5 bar | Prevents the torque converter housing from ballooning due to high pressure. |
| Normal Operating Oil Temp. | 80°C - 100°C | Standard temperature range during continuous duty cycles. |
| Max. Allowed Transient Oil Temp. | 120°C | Exceeding this limit triggers the transmission high-temperature alarm. |
| Initial Oil Refill Capacity | Approx. 45 - 65 Liters | Varies based on the size of the OEM's external radiator and cooling lines. |
| Recommended Oil Specification | ZF-TE-ML 03 certified transmission fluid | Strictly forbidden to mix with general or universal hydraulic fluids. |
Physical & Electrical Characteristics
| Parameter Item | Details / Standard Value | Remarks |
|---|---|---|
| Total Dry Weight | Approx. 680 kg - 820 kg | Excludes operating fluids; varies by output drop/drop-box configuration. |
| Structural Design | Powershift (Countershaft type) | Gears are constantly in mesh; shifting is managed via multi-plate wet clutches. |
| Transmission Control Unit (TCU) | ZF EST-37 or EST-117 series | Responsible for shifting logic calculation and fault code diagnostics. |
| Solenoid Valve Type | Proportional Valves | Enables smooth, modulated clutch pressure adjustments rather than on/off spikes. |
| Sensor Configuration | Input speed, turbine speed, output speed, oil temperature sensors | Forms a closed-loop system for automatic shifting and gear overlap protection. |
