Automatic Repaired DSG Transmission

The repair and remanufacturing process focuses on the core mechanical integrity of the 12JS series, ensuring that the gear teeth, synchros, and hydraulic actuators meet original factory tolerances. By utilizing a specialized Automatic Transmission Direct Shift Gearbox, operators can maintain the specific torque curves required for long-haul logistics and mining operations without the high cost of a brand-new factory unit.

Advantages

● 12-Speed High-Torque Capacity

The 12JS160T/180T/200T models are built to sustain the high input torque of 11L to 13L engines, preventing gear slippage or overheating under full-load hauling.

● Rapid Shift Response

The dual-clutch design allows for faster gear engagement compared to standard manual transmissions, which reduces clutch wear and improves acceleration efficiency on steep grades.

● OEM Mounting Compatibility

These Automatic Repaired DSG Transmissions use standard Shaanxi and MAN bell housing patterns and output shaft splines. This ensures the transmission bolts directly to the engine and driveshaft without requiring custom adapters or modifications.

● Calibrated Hydraulic Control

The internal valve body and solenoids are tested to ensure the shift logic matches the original engine ECU, preventing "gear hunting" and ensuring smooth torque delivery at low RPMs.

● Verified Mechanical Durability

Every repaired unit undergoes load-testing to confirm the structural integrity of the casing and the precise alignment of the countershafts, ensuring the gearbox can withstand continuous high-vibration environments.

What's Automatic Repaired DSG Transmission?

The Automatic Repaired DSG Transmission is a dual-clutch gearbox that automates the shifting process of a heavy-duty 12-speed manual transmission. It uses one clutch for the odd gear sets and another for the even gear sets, allowing the gearbox to engage the next gear while the previous one is still under load.Product ApplicationThis transmission is a primary replacement part for heavy-duty trucks equipped with Shaanxi, MAN, or Foton drivetrains. It is specifically used in 371HP to 540HP models (such as HOWO T7H and C7H) operating in logistics, infrastructure, and heavy-cargo transport where high-frequency shifting and heavy towing capacity are required.

FAQ

Q: How do the 160T, 180T, and 200T models differ?

A: The numbers represent the maximum input torque capacity (e.g., 1600Nm, 1800Nm, and 2000Nm). Choosing the correct model depends on your engine’s horsepower and the total weight of the loads you intend to haul.

Q: Is this transmission compatible with the HOWO T7H series?

A: Yes, these 12-speed units are the standard configuration for many T7H and C7H models using MAN or Sinotruk engines. We recommend checking the spline count on your input shaft to confirm an exact match.

Q: Does the repaired unit include the internal electronics?

A: The DSG Transmission Assembly Automatic Gearbox comes with the integrated control unit and solenoids already installed and tested, allowing for a "plug-and-play" installation with the vehicle's existing wiring harness.
