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 GWM 7-speed wet dual-clutch transmission fitted to the third-generation Haval H6 (2021-on) has documented clutch pack wear and judder, particularly in low-speed manoeuvring and city traffic. Early production units exhibit difficulty engaging from rest and shuddering at 20–40 km/h. GWM issued TCU software updates but mechanical clutch wear is also reported on higher-mileage units. Documented extensively across AU and NZ owner communities.

What you would notice

Shuddering or vibration when pulling away from rest
Hesitation and lurch when engaging first gear from a standstill
Transmission hunting between gears at low speed in traffic
Judder during slow-speed manoeuvring in car parks

How to check it

What it costs to put right

$2,000 to $5,500 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

“Any shuddering or hesitation when pulling away from a complete stop?”
“Has the TCU been updated or the transmission serviced by GWM?”
“Has the vehicle been returned to the dealer for any transmission complaints?”
