What is the MLGU gearbox?

The MLGU is a 5-speed manual gearbox used across PSA Group and Fiat vehicles. It is a compact transverse-mounted unit found in a range of small to mid-size cars.

How do I confirm the tooth count on my mainshaft?

The tooth count must be confirmed by physically counting the teeth on the existing shaft once the gearbox is open. There is no external marking to identify tooth count without opening the gearbox.

Is this a genuine OE part?

Yes — part number 9805836280 is the original equipment part number for this shaft in the MLGU application.

What causes pinion mainshaft failure?

Tooth damage from lack of lubrication, contaminated gearbox oil or forceful gear engagement without the clutch fully depressed. If the shaft is damaged, adjacent gears and bearings should also be inspected.
