Signs That Your Gearbox Needs Replacing

On a Corsa 1.3 CDTi, several warning signs point to a worn gearbox: stiff or hesitant gear changes, crunching when downshifting into second or third, difficulty finding neutral when stationary, vibrations felt through the gear lever under acceleration, a dull rumbling noise that varies with engine speed, or a small gearbox oil leak visible beneath the vehicle. Any of these symptoms warrants a prompt inspection of the gearbox.

Exchange Gearbox, Rebuilt to 0 km

This GM-BZ4 gearbox is reconditioned through a comprehensive process: full strip-down, cleaning and inspection of every component, replacement of internal wear parts including gears, synchros, bearings and seals, followed by reassembly to manufacturer tolerances and a final bench test before dispatch.

Sold on an exchange basis and rebuilt to 0 km, the gearbox is dispatched before the old unit is collected – the old unit is not recovered until after delivery, so the garage is never left without a gearbox and the vehicle is not off the road. Return of the old gearbox, with its casing intact, is required after fitting, in accordance with our Terms and Conditions.
