Reconditioned Opel Corsa 1.4 Turbo Gearbox – 5-Speed Manual – Ref. GM-AP4

Reconditioned Opel Corsa 1.4 Turbo Gearbox GM-AP4

This reconditioned gearbox for the Opel Corsa 1.4 Turbo (1364 cm³) is compatible with engine codes A14NET, A14NEL, B14NET, B14NEL, B14NEH and B14NEJ, and carries the reference GM-AP4. It is a 5-speed manual gearbox, fully stripped, cleaned and inspected before reconditioning: worn gears, synchros, bearings and seals are replaced, then the unit is reassembled to manufacturer tolerances and bench-tested before dispatch.

Signs that your gearbox needs replacing

On a Corsa fitted with the 1.4 Turbo, several warning signs point to a worn manual gearbox:

• stiff or crunching gear changes, particularly on downshifts;
• difficulty engaging second gear when cold;
• vibrations or grinding noticeable in neutral;
• unexpected gear jumping under acceleration;
• a metallic noise that persists even with the clutch pedal depressed.

These symptoms indicate internal wear of the gears or synchros and justify replacing the gearbox with a reconditioned GM-AP4 unit.

Exchange basis: immediate dispatch, deferred collection

This gearbox, rebuilt to 0 km, is dispatched straight away without waiting for the old unit to be collected first — so the garage is never left without a gearbox and the vehicle is not kept off the road. The old gearbox, with its casing intact, is only collected after the GM-AP4 has been delivered and fitted. Return of the old unit is required, in accordance with our Terms and Conditions.
