What goes wrong

The most commonly reported drivetrain complaint on SZ Territorys, especially diesels, is failure or shudder of the ZF-sourced six-speed auto's torque converter, felt as a vibration at light throttle cruising. As with the FG Falcon, Ford's 'lifetime fluid' claim means many were never serviced, accelerating valve body and converter wear. Caught early, a fluid service can mask or slow it; a converter replacement or rebuild is a four-figure job.

What you would notice

  • Rumble-strip shudder at light throttle around 60-100 km/h
  • Harsh or flared shifts when warm
  • Clunk coming to a stop

How to check it

Where to look. Transmission and torque converter — felt through the vehicle on the test drive

  1. Drive at a steady 60-100 km/h with light throttle and feel for a fine shudder through the floor.

  2. Test all shifts warm.

  3. Ask for proof of a ZF fluid and filter service — its absence on a 150,000 km car means budgeting for one immediately.

Parts involved: Torque converter.

What it costs to put right

$600 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

  • “Has the transmission fluid and filter ever been changed?”
  • “Does it shudder at light throttle at open-road speeds?”
