Mitsubishi Canter: Duonic dual-clutch transmission shift faults, clutch solenoid contamination and clutch wear (8th gen FEA/FEB/FEC Duonic)

Duonic dual-clutch transmission shift faults, clutch solenoid contamination and clutch wear (8th gen FEA/FEB/FEC Duonic) is a common transmission fault on the Mitsubishi Canter on the 2011–2020 cars, and we rate it critical. Putting it right costs $600 to $16,000 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 6 documented faults on the Mitsubishi Canter.

What you are looking at

No photograph available

We do not hold a verified photograph of the Clutch yet. We would rather show none than show a picture of a different part.

What goes wrong

The six speed Duonic dual clutch automatic fitted from 2011 had debris left inside from the factory that could lodge in the clutch control solenoid valve, causing harsh or flaring shifts, noise and in the worst case no drive or a stall. Australia recalled 2011 to 2013 trucks (REC-001068) for a flush or transmission replacement, plus a separate recall for ATF hoses that could come off their clamps (REC-001066), and the US ran the same contamination recall (14V-046). Beyond the recall, owners report repeat Duonic replacements and worn clutch packs, made worse by holding the truck on a hill with the throttle. A failing Duonic is one of the most expensive repairs on the truck.

What you would notice

Jerky, slow or flaring gear changes
Gear hunting or delay pulling away from a rolling start
Transmission warning lamp or truck stuck in neutral
Grinding or whining noise from the gearbox; ATF drips under the truck

How to check it

Where to look. Duonic dual clutch gearbox behind the engine under the cab, ATF hoses and cooler lines along the gearbox

On a test drive pull away gently and firmly from a stop, including uphill, and feel for shudder, slipping or a delay before drive engages. Go through all six gears and back down while slowing, feeling for flare or bang between gears. Try reverse and parking manoeuvres at walking pace. Watch the dash for a transmission warning lamp. Look under the truck behind the engine for red ATF drips on hoses or the ground. Ask for proof the Duonic contamination and ATF hose recalls were done and whether the gearbox or clutch has been replaced. If a workshop inspection is possible: have a Fuso capable scan tool read transmission codes, clutch wear values and adaptation data, and check the ATF condition for debris.

Parts involved: Clutch.

What it costs to put right

$600 to $16,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, 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

“Were the Duonic contamination and ATF hose recalls done?”
“Has the gearbox or clutch ever been replaced?”
“Does it ever get stuck in neutral or show a transmission warning?”
“When was the ATF last changed?”

Mitsubishi Canter buyer questions

Is duonic dual-clutch transmission shift faults, clutch solenoid contamination and clutch wear (8th gen fea/feb/fec duonic) serious on a Mitsubishi Canter?

We rate it critical and common on the Mitsubishi Canter. The six speed Duonic dual clutch automatic fitted from 2011 had debris left inside from the factory that could lodge in the clutch control solenoid valve, causing harsh or flaring shifts, noise and in the worst case no drive or a stall. Australia recalled 2011 to 2013 trucks (REC-001068) for a flush or transmission replacement, plus a separate recall for ATF hoses that could come off their clamps (REC-001066), and the US ran the same contamination recall (14V-046). Beyond the recall, owners report repeat Duonic replacements and worn clutch packs, made worse by holding the truck on a hill with the throttle. A failing Duonic is one of the most expensive repairs on the truck.

How much does it cost to fix on a Mitsubishi Canter?

$600 to $16,000 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Mitsubishi Canter years are affected?

Our research records this fault on the 2011–2020 Mitsubishi Canter. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
