What you are looking at

No photograph available

We do not hold a verified photograph of the Mechatronic / valve body yet. We would rather show none than show a picture of a different part.

What goes wrong

C3s with the conventional 4-speed automatic use the PSA/Renault AL4 - a gearbox notorious for harsh, clunky shifting and dropping into 3rd-gear limp mode with a 'gearbox fault' message. The usual culprits are the two pressure-regulation solenoid valves and degraded fluid; the fix (later-type solenoids, fresh fluid and a software update) is relatively cheap, but neglected boxes progress to valve-body or full gearbox failure. Treat 'it just needs a service' claims with suspicion and price a proper repair into your offer.

What you would notice

Harsh or clunky 2-3 shifts, especially when hot
Snatch or thump when slowing to a stop
'Gearbox fault' message and stuck in 3rd gear (limp mode)
Delay engaging Drive or Reverse

How to check it

Where to look. Automatic transmission - transverse, left side of engine bay; solenoids inside the gearbox behind the side cover

Test drive until the gearbox is fully hot (20+ minutes, town driving) - AL4 faults often only appear warm.
Feel for hard shifts and any snatching when coming to a stop.
Ask when the fluid and solenoids were last done; the AL4 is 'sealed for life' on paper but needs fluid every 60,000 km in practice.

Parts involved: Mechatronic / valve body.

What it costs to put right

≈A$550 to ≈A$2,760 at independent workshop rates, shown as an approximate guide in Australian dollars. That is for this job on its own, not for the car.

An estimate, converted to Australian dollars, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Has the gearbox ever gone into limp mode or shown a gearbox fault message?”
“When were the AL4 fluid and solenoids last replaced?”

Now check the Citroen C3 you are actually looking at

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car still has money owing on it, has been written off or reported stolen, what kms it showed in past sale ads, whether it has had accident repair claims and what it is worth today. That comes from the official records for that plate. Enter the plate and its state for the A$17.90 Vehicle Check, or the full history from A$24.99.

Which Citroen C3 years are affected?

Our research records this fault on the 2002–2010 Citroen C3.
