Reconditioned Opel Corsa 1.4 Gearbox – 5-Speed Manual – Ref. GM-B66

Reconditioned Opel Corsa 1.4 Gearbox – Reference GM-B66

This reconditioned gearbox is designed for the Opel Corsa fitted with the 1.4 petrol engine (1364 cm³), and is compatible with engine codes Z14XEP, A14XER and A14XEL. Referenced as GM-B66, this 5-speed manual gearbox undergoes a full reconditioning process before being returned to service, restoring near-new performance to your Corsa.

Signs That Your Gearbox Needs Replacing

On a Corsa 1.4, several warning signs point to wear in the 5-speed manual gearbox: increasingly stiff gear changes, crunching when downshifting, difficulty engaging reverse, jerking when shifting into second or third, unusual vibrations in neutral, or a gear lever that feels spongy and imprecise. An oil leak from the casing, a grinding noise under acceleration, or a gear that slips out on its own are also signs you should not ignore before the problem gets worse.

Exchange Basis: The Fast, Reliable Solution

This gearbox is fully stripped, cleaned and inspected component by component. Any gears, synchros, bearings and seals showing signs of wear are systematically replaced, before the unit is reassembled to manufacturer tolerances and bench-tested to verify that every gear functions correctly. Under this exchange arrangement, the reconditioned GM-B66 gearbox is dispatched to you first, without waiting for your old unit to be collected — so your garage is never left without a vehicle and the car can be back on the road quickly. Once the GM-B66 has been fitted by a professional, your old gearbox — with its casing intact — must be returned; this return is mandatory in accordance with our Terms and Conditions.

Compatibility

The GM-B66 reference covers Opel Corsa models fitted with the 1.4 petrol engine, paired with engine codes Z14XEP, A14XER and A14XEL. Before placing your order, we recommend confirming the exact match with your vehicle using the registration document or the identification plate on the gearbox casing.
