Stone Street, Bunbury

The workshop the South Westsends its gearboxes to.

P & D Autos has been servicing and repairing cars on Stone Street for years, and Bunbury Automatics, the transmission and torque converter specialists, now works out of the same workshop. Log book servicing on a new car, or a gearbox stripped and rebuilt on the bench. Same building, same people.

Everything a car needs, under one roof

At P & D Autos we ensure that workshop practices provide a consistently high quality for all service and repair work. That is the whole idea: whatever you drive, it gets correctly diagnosed, repaired and serviced, and you are not sent somewhere else halfway through the job.

Ask us about your car

Log book servicing

Full log book servicing to most popular makes and models, carried out without affecting your warranty.

Mechanical repairs

General repairs across all makes, from the small things that turn into big things to the jobs nobody else wants to look at.

Diagnostics

Faults found properly before anything is replaced. Correctly diagnosed, repaired and serviced, right the first time.

Auto electrical

Electrical faults traced and repaired, including the ones that only show up when the car is warm or the road is rough.

Tyres and wheel aligning

Tyres supplied and fitted, and wheel aligning done on site so you are not sent across town for it.

Alarms and immobilisers

Vehicle alarms and immobilisers supplied and fitted.

Genuine spare parts

We can obtain genuine spare parts for all makes of vehicles, not just the ones we sell you.

Accessories

Accessories sourced and fitted while your car is already with us, rather than as a second trip.

Bunbury Automatics and Torque Converters

Gearboxes are not a sideline here

Bunbury Automatics built its reputation across the South West on one thing: sound engineering on transmissions. It is now part of P & D Autos, and the same work carries on in the same workshop.

Our experts in the workshop are capable of rebuilding and repairing all makes and models of automatic and manual gearboxes, including electronic gearbox control systems. Repair, reconditioning and fitting are all carried out on site, so your gearbox does not go on a truck to Perth and come back a fortnight later.

The cars we know inside out

We work on everything, but there are makes we have spent years with, and it shows in how quickly we find a fault.

Our specialism

Jeep, Chrysler and Dodge

These are the ones we are known for. Servicing, repairs and parts, with technicians who have seen the same quirks often enough to recognise them straight away.

Also looked after

European, new and old

P & D Autos can service, repair and supply parts for all European vehicles new and old, including new vehicle servicing carried out without affecting your warranty.

  • Saab
  • Citroen
  • BMW
  • Volvo
  • Audi

Run by Paddy, and it shows

The workshop is led by Pasquale Catalano, better known to just about everyone in Bunbury as Paddy. He has been in the automotive industry since he was fifteen years of age, and Domenica runs the office, the accounts and most of the phone calls you will have with us.

That is the reason people keep coming back rather than shopping around. You get told the cost before the work happens. You get rung with an update rather than left wondering. And the car goes home clean.

The South West region is a growing community and P & D Autos has been growing with it.

P & D Autos

As automotive technology becomes increasingly complex, the traditional toolbox is becoming virtually obsolete. So you have the backing of a technologically advanced workshop with fully trained technicians, that have regular ongoing refresher training, to keep up to date with today’s fast moving technology.

What happens when you book it in

Nothing clever, just the way it should work.

01

You ring, we book it in

One phone call to the workshop. You speak to the people who will actually have the car, not a call centre.

02

We find out what is really wrong

The fault gets diagnosed first. We would rather spend the time finding it than guess and hand you a bill for parts you did not need.

03

We ring you with the cost

Before the spanners come out you get a phone call telling you what it needs and what it will come to. No surprises when you collect it.

04

You get it back clean

The job gets done and the car comes back washed and vacuumed. Our customers keep mentioning it, so we keep doing it.

What people say afterwards

Every one of these is a real Google review left by a customer.

I had an excellent experience with this workshop. From the very beginning, everyone was incredibly friendly and helpful. They took my car in straight away, inspected it promptly, and completed the service along with replacing a few parts. Not only was the work done quickly and to a high standard, but they also went the extra mile by cleaning my car inside and out. The whole experience was smooth, professional, and stress-free. I highly recommend them to anyone looking for honest, efficient, and high-quality service. Thank you P&D ❤️

On a recent trip to Bunbury, our car developed an electrical fault in the gearbox that left the car undrivable. We limped to P & D Autos to see if they could assist with the problem as we had another appointment to get to. They immediately stopped a technician doing what he was doing and assigned him to diagnose the issue. When the result showed it could not be easily solved they gave us a courtesy car to make our appointment, while they continued to pursue the problem. A couple of hours later they called and informed us the problem had been resolved. Without their invaluable knowledge, time and care, we would have been stranded and looking at the expense of having the car sent to Perth.

WOW! By far the BEST mechanic business I have come across! Booked in for an overdue service as have been travelling around Aus for 7 months. Friendly, family run business that went above and beyond, rang me with updates every step of the way, told me the cost so no hidden surprises, fixed my squeaky suspension and even gave my car a wash and vacuum! VERY impressed, thank you Paddy and Dominica!

Can not fault their customer service and care. Always rings to discuss issues and updates. Nothing is too much for them. They go above and beyond to make sure your happy and that the car is far greater than when it went in. They even wash your car. They are honest and reliable. Dominica the receptionist, is friendly, courteous and professional. Very nice dealing with her.

Come and see us on Stone Street

Ring the workshop and we will find you a spot. If it is a gearbox, tell us what it is doing and roughly when it started, that usually saves everyone a lot of time.
