Frequently Asked Questions

Q: How do I identify which gearbox my van has?
A: The M40 gearbox is commonly fitted to Fiat Ducato, Citroen Relay and Peugeot Boxer vans. You can confirm by checking the gearbox code stamped on the casing, or send us your VIN and we will advise.

Q: Is this an OEM or aftermarket part?
A: This is a quality aftermarket replacement manufactured by SRT, a specialist in manual gearbox components.

Q: What is the tooth count and why does it matter?
A: Z:37 means this gear has 37 teeth. The tooth count must match exactly when replacing a gear to maintain the correct gear ratio.

Q: Can I fit this gear without replacing the mating gear?
A: It is generally recommended to inspect the mating gear for wear when replacing any gear. If the mating gear shows similar wear, replacing both simultaneously will give a longer service life.

Q: Do you stock other M40 gearbox parts?
A: Yes — Eco Torque stocks a comprehensive range of M40 gearbox components including gears, synchronisers, bearings and seals.
