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 optional TCT (Twin Clutch Transmission), an Aisin-sourced 6-speed dry dual-clutch unit, is notorious for jerky and shuddering behaviour at low speeds and during parking manoeuvres. The dry-clutch design wears prematurely in urban traffic and the transmission control software struggles with smooth engagement below 20 km/h. Alfa Romeo issued a software service campaign in multiple markets to update TCT control logic and replace clutch actuator components. On high-mileage examples both clutch packs require full replacement — a significant cost that materially affects resale pricing.

What you would notice

Shudder and lurch during low-speed manoeuvring and parking
Hesitation pulling away from rest
Clunking or jolt when engaging Drive from Park or Reverse
Gearshift hunting or refusal to engage below 20 km/h

How to check it

Where to look. Centre of vehicle, transmission tunnel, dual-clutch unit and actuator assembly

Test drive in slow car-park traffic with multiple pull-aways from rest. Any shuddering, lurching, or hesitation pulling away is a red flag. Ask specifically whether a TCT software update has been applied at an authorised Alfa dealer. If a workshop inspection is possible: Check for TCT fault codes with an OBD reader.

Parts involved: Clutch.

What it costs to put right

$1,500 to $3,500 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

“Has the TCT software ever been updated at an Alfa Romeo dealer?”
“Has the transmission ever been serviced or had clutch packs inspected?”
“Does the car shudder or jerk when pulling away slowly in traffic?”

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
