Reconditioned Opel Astra 1.4 Gearbox: Reference GM-U6
This reconditioned gearbox for the Opel Astra 1.4 petrol, with an engine capacity of 1364 cm³, carries the reference GM-U6 and is compatible with the following engine codes: Z14XE, Z14XEP, A14XER, A14XEL, A14NET. The reconditioning of this 5-speed manual gearbox follows a rigorous process: full strip-down, thorough cleaning and inspection of every component, followed by replacement of any gears, synchros, bearings and seals showing signs of wear. The unit is then reassembled to manufacturer tolerances and bench-tested before being returned.
Signs That Your Manual Gearbox Needs Replacing
On an Astra fitted with this 1.4 unit, several warning signs should prompt the driver to act before the problem worsens:
- stiff, jerky or completely blocked gear changes, particularly on second or third
- crunching, grinding or metallic noises when changing gear
- a gear jumping out or refusing to stay engaged once the car is moving
- visible oil leak beneath the gearbox casing
- unusual vibrations or a persistent background noise under acceleration
Your Unit Rebuilt and Ready to Fit
With this service, you send in your own GM-U6 gearbox to be fully rebuilt. Every internal wear component is inspected and replaced as required, then the unit is reassembled to manufacturer tolerances and bench-tested to confirm correct operation. Your reconditioned gearbox is then returned to you, ready to be refitted to your Opel Astra 1.4. This solution lets you keep your original unit while restoring it to as-new performance.
Compatibility
The GM-U6 reference fits Opel Astra models equipped with engine codes Z14XE, Z14XEP, A14XER, A14XEL and A14NET. Before placing an order, always check that one of these codes matches the engine code stamped on your vehicle's engine block, to ensure full compatibility with this gearbox.
Warranty and Payment
This rebuilt gearbox comes with a 24-month parts warranty, subject to fitting being carried out by a qualified professional. Your order can be spread over several instalments – pay in up to 10 instalments – to help manage your budget.
EDEN BOITES supports you from quote through to the return of your rebuilt unit.
