Astra H: M32 six speed manual, bearing and synchro wear

expensive

In the Astra H diesel range, on the Z17DTH engine, two manual gearboxes were available: the five speed F23 and the six speed M32.

Show the rest

The known weakness of the M32 is wear of the bearings and the synchro rings: a whine while driving, a stiff shift, especially 3rd to 4th. Replacement or a rebuild is expensive.

between 100,000 and 200,000 km

What to check

Count the gears: 6 raises the M32 suspicion on this engine group; 5 means more likely the F23
When warm, at 80 to 100 km/h, listen for gearbox whine: a noise that rises with the revs is suspect
Try the 3 to 4 and 4 to 5 shifts cold and warm: binding, scratchiness

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

A fault on the list does not mean the car you are looking at has it.
A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
