Why Is Reman Better Than New?
Many people assume “new” means better – but with TraXon gearboxes, that’s not always the case.
A remanufactured TraXon gearbox is often stronger and more reliable because it’s rebuilt with the latest fixes and improvements, many of which factory-new units do not include.
Here’s why:
- Upgraded with the Latest Fixes
Every reman gearbox is rebuilt with the newest OEM-level updates and corrections for common TraXon issues.
- Thoroughly Tested & Proven
Each unit is completely stripped, cleaned, rebuilt and dyno-tested under load to ensure perfect gear selection, clutch performance, and hydraulic control.
- Cost-Effective
You get like-new performance for significantly less than a new unit – without the long wait times.
- Environmentally Friendly
Remanufacturing reuses major metal components, reducing waste and environmental impact.
- Locally Supported Warranty
No waiting for imported parts or overseas warranty claims. Your TraXon gearbox is supported locally by Mayfair Gearbox.

The Backbone of Your Fleet
Your gearbox is the critical link between your truck's heavy-duty engine and the wheels. Whether you drive a MAN TGS, DAF XF, UD Quon, or Iveco Stralis, chances are you are relying on ZF technology. You need a partner who understands the difference between an Ecosplit (Manual) and an AS Tronic or TraXon (Automated).
How It Works
Unlike car gearboxes, ZF truck transmissions utilise complex pneumatic (air) systems to manage range changes and split gears. They are designed to multiply torque to move massive loads. A failure in the "mechatronic" system (the brain) or the pneumatic actuators (the muscle) can stop a 50-ton rig in its tracks.
What Are the Symptoms of a TraXon Problem?
What Are the Signs of Failure?
In the commercial sector, ignoring a symptom can destroy an entire gearbox casing.
- Shift Refusal: If the truck hesitates or hunts for gears, the clutch actuator or travel sensors may be failing.
- Air Loss: Since these gearboxes shift using air, any leak in the system can cause the gearbox to burn out synchronizers by attempting to shift without full pressure.
- Overheating: Heavy loads generate heat. A burning smell or discoloured oil indicates the transmission cooler has failed or the oil has degraded, leading to rapid internal wear.
