What goes wrong with Opel's M32 gearbox?

The six-speed M32 manual, fitted to GM-era Astra, Zafira, Meriva and Insignia models, can wear out its bearings. The warning signs are a whine in fifth and sixth or a gear lever that rocks when you lift off.

Do newer manual Opels use Peugeot gearboxes?

Yes, since Opel joined Stellantis the recent Corsa, Astra, Mokka and Grandland share six-speed manual gearboxes with Peugeot and Citroën. Parts and servicing are common to many cars in the group.

What should I check on a used manual Opel diesel?

On manual Opel diesels, check the dual-mass flywheel and the clutch, which suffer from town driving. Vibration when pulling away or a rattle at idle points to a tired flywheel.
