Lost drive on the road?
If the car won't move, won't select a gear, or a warning light comes on with a burning smell, get off the road if you can, switch off and put the hazard lights on. Call roadside assistance if you have it. If anyone is hurt or in danger, call 000.
What Melbourne asks of a gearbox
Traffic, mostly. Peak hour means a take-off from a standstill every few car lengths, and every one of those is work for the clutch packs, the torque converter or the clutch you press. RACV says heavy stop-start traffic and towing are among the conditions that can call for servicing around every six months.
Then there are the hills. The Dandenong Ranges, about 35 km east of the city, climb to 633 m at Mount Dandenong, on roads that are steep and winding. A loaded car on those grades, up and back down, is a fair test of a tired gearbox.

Towing to the coast or the hills
RACT says transmission faults on the road can be more common when towing a trailer, boat or caravan. RACQ says heavy towing with an automatic often calls for an extra or larger transmission cooler, and some towing packages make one mandatory. Ask about it before a summer of towing, not on the way.
Bought from a Victorian dealer lately?
A used car from a licensed motor car trader that was under 10 years old and had done under 160,000 km comes with a statutory warranty of 3 months or 5,000 km, whichever ends first. If the gearbox plays up inside that window, go back to the trader before anyone else opens it.
No register to check
Victoria doesn't license mechanics, so ask who will actually work on the gearbox and how many of your type they've done. Consumer Affairs Victoria says to check that the staff are qualified and the business has the equipment for the job, and a gearbox on the bench needs both.
Questions to ask before you agree to a rebuild
- What did the scan and the road test actually show?
- Is the fluid the right type and at the right level, and is anything leaking?
- Could a sensor, wiring fix or software update sort it before the gearbox comes out?
- For this car, what are the options: repair, reconditioned or replacement?
- What warranty comes with the unit, and with the labour?
Limp mode on the freeway
If the car suddenly won't rev or go above a low speed, it may be in limp mode. RAC says that's the car protecting the engine and transmission after its sensors pick up a serious problem, and a transmission fault is one of the triggers.
Pull over somewhere safe first. RAC says switching off for around 30 seconds and restarting, or letting it cool for about 20 minutes, may bring it out, but the cause still needs finding. Limp mode goes through it.
If it were our car
We'd go easy on it from the moment the gearbox felt wrong, and get it diagnosed while the fault is still small. If it's inside a Victorian dealer's statutory warranty, the trader gets the first call. Otherwise we'd send it to a mechanic who sees that type of gearbox every week, and get the fault and the options written down before saying yes to anything big.
