About Us

N & K Transmissions Pty Ltd is an Australian owned & operated organisation established since 1996. We specialise in remanufacturing ZF Ecomat & Mercedes Benz Automatic Bus Transmissions. Over the years we have become a leading & reputable rebuilder of automatic transmissions in the bus industry. We have a dedicated & experienced team with our leading technician having over 25 years of ZF Ecomat knowledge.


Our passion & commitment over the last 17 years has enabled us to build the reputation of a reliable & efficient transmission repairer, providing an incomparable service to continually meet the ongoing demands of our customers.


N & K Transmissions has recently re-located premises to a purposely built facility, conveniently located in the Dunheved Business Circuit in St Marys, NSW.

Our custom workshop has been specifically designed for our specialised industry, this includes a well equipped dismantling & cleaning area as well as a controlled assembly environment. We are also equipped with all the necessary testing equipment including a transmission test bench that precisely checks the transmissions pressures & has the capabilities of load testing  the transmission in all gears, so that  you can feel assured that your transmission has undergone a thorough testing procedure prior to vehicle installation.


N & K Transmissions strives to uphold an environmentally friendly surrounding, we understand the importance of reducing our impact on the environment. We not only recycle our internal waste, but also offer our customers with an alternative of using remanufactured components that are reclaimed to perform as per original standards, and in some cases even improving the part based on our many years of experience on the ZF Ecomat & Mercedes Benz product. This alternative not only reduces the price, but is also helping our impact on the environment by re-using old components rather than replacing with new, without affecting the quality of the rebuild.
