About the Signum

The Vauxhall/Opel Signum was an executive-class five-door hatchback built from 2003 to 2008 – effectively a longer, more luxurious version of the Vectra C aimed at the upper D/E-segment. Eco Torque holds one of our deepest Signum transmission ranges, centred on the M32 6-speed manual – gears and shafts, synchro hubs and rings, selector parts, differentials, bearing & seal kits and full rebuild kits – plus F17 5-speed internals, F40 6-speed repair parts, LuK dual-mass flywheels and clutch kits, and gearbox oil service kits.

Depending on engine the Signum used the F17 5-speed on smaller units, the M32 6-speed on most petrol and diesel models, and the heavier-duty F40 6-speed on higher-torque diesels (automatics were also offered). The M32's output bearings are a well-known wear point that our rebuild kits address. Not sure which parts you need? Send us your registration or VIN and we'll help.

Gearboxes fitted: M32 (6 Speed), F17 (5 Speed), F17 Easytronic (5 Speed), F40 (6 Speed)

Frequently Asked Questions

What gearbox and transmission parts do you stock for this vehicle? +
We stock a comprehensive range of manual gearbox, DSG, DCT and automatic transmission parts including clutch kits, flywheel modules, bearings, synchro rings, seals, rebuild kits and gearbox oil. Browse the full range above or filter by gearbox type.
How do I identify my gearbox type? +
Your gearbox code is stamped on the gearbox casing — typically 2 to 3 letters on VAG vehicles or a number and letter code on others. You can also check your vehicle service documents, use a VIN lookup, or contact our team with your registration for help identifying the correct code.
Do you stock both manual and automatic transmission parts? +
Yes — depending on the model we stock parts for manual gearboxes, DSG dual-clutch units, and traditional automatic transmissions. Use the filters above or browse by gearbox code to find parts for your specific unit.
How do I know the parts are compatible with my exact model? +
We recommend confirming your gearbox code before ordering, as parts can vary between production years and engine variants even within the same model range. Our team is happy to cross-reference your gearbox code and confirm compatibility.
How long does delivery take? +
Most in-stock items are dispatched next working day from our UK facility. Next-day delivery is available on qualifying orders placed before our daily cut-off. Some specialist or sourced-to-order items may have longer lead times — check individual product listings for details.
Do the parts come with a warranty? +
Yes — all parts come with a standard warranty. Clutch kits and flywheel modules typically carry a manufacturer warranty. Full details are on each product listing.
Can I search by my registration number? +
You can provide your registration number to our team and we will help match the correct gearbox code and parts for your vehicle. Use the contact page or give us a call.
Do you offer technical support? +
