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

Mazda2 DE and DJ models with automatic transmission develop a shudder or judder during light-throttle take-up when fluid has not been changed within 60,000 km intervals. Fluid breakdown allows clutch pack micro-slip, producing a vibration felt through the drivetrain at low speed. Early DE examples used a conventional 4-speed auto; later DE and DJ models use CVT-style units that are particularly sensitive to fluid condition.

What you would notice

Vibration or shudder at 20-50 km/h during light acceleration
Hesitation or slip sensation when pulling away from rest
Delayed engagement from P or N into D
Jerky downshifts under light braking

How to check it

Where to look. Transmission unit, undercentre of vehicle

Drive at low speed on flat road with light throttle and feel for shudder through seat and floor.
Check ATF colour and smell - should be pink/red, not brown or burnt.
Ask service history specifically for ATF change records.

Parts involved: Clutch.

What it costs to put right

$300 to $1,800 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

“Has the automatic transmission fluid ever been changed?”
“Any judder or shudder when pulling away from rest?”
“Has the car been used mainly for short-trip city driving?”
