Terms and conditions. 
Below you’ll find all the key information about our gearbox warranties, service requirements, and customer responsibilities. It’s not just the small print — it’s how we make sure everything runs smoothly and fairly for everyone.

No Oil Supplied Unless Fitted by Us 

Gearboxes are supplied without oil unless they are fitted by our team. It is the customer’s responsibility to fill the gearbox correctly — incorrect oil levels are the most common cause of failure. If you need any help with this please contact us and we will help you through any difficulty you may be having. 

Conditions of warranty

Private Vehicles: 12 months or 12,000 miles (whichever comes first)

Commercial Vehicles: 6 months or 6,000 miles (whichever comes first)

All warranties cover faults in construction or defective parts only.

Warranty work must be returned to us at the customer’s cost.

Any delay in reporting or returning a faulty unit may void the warranty.
 

Gearbox must be installed by a competent, qualified professional.

No warranty will apply if:

The gearbox is incorrectly fitted or filled.

The vehicle has been used for racing, off-roading, or modified (e.g., lowered suspension, remapped ECU, non-standard wheels).

Continued use after a fault has been detected causes further damage.

Abuse or misuse is identified by our technicians.
