About Us

Dal-Trans began in Villawood (NSW) back in 1976 in a two bay workshop; with a Cummins engine background, the business began with truck engine rebuilds and installs followed by transmission conversions. It was from here that the vision for Dal-Trans’, connection with the automatic transmissions for all ranges of trucks and buses, was born.

In 1978 Dal-Trans was appointed as an Authorised Allison Dealer and in 1980 the business moved to our recently renovated 5 bay premises in Wetherill Park. Over the next 40 years, we worked to become the most distinguished and respected authority on Allison Transmissions. A reputation is not something renewed every 12 months but built over years; an accomplishment that we’re very proud of.

As an Australian & family-owned business, we are specialists for all makes of automatic transmissions, in particular Allison Transmission, spare parts, application & support, overhaul and regear as well as routine maintenance, servicing and repair. This has resulted in Dal-Trans becoming the preferred supplier to OEM Dealerships, Local & State Government affiliates, transport companies & the emergency services. Following over a 25-year association with Parker, we are proud to be an authorised distributor for the supply and support of the Chelsea PTO products. It is with pride that we service a wide range of customers, large and small, from Government and Fleet as well as owner-operators. We currently boast over 120 years of combined Allison experience; a result of training and long-serving professional and qualified staff in the business.

The quality and reliability of an Allison transmission are unrivalled, as is our commitment to provide quality service to the highest level to ALL of our customers. Our focus is and has always been, getting vehicles and owners back on the road as we know when your vehicle is not working, you’re not earning an income.
