Our Story

Our story starts back in the late 70’s when three young, eager twenty something’s were over in the UK on their big OE.

Living and working in London as mechanics on Detroit Diesel engines and Allison transmissions, they salvaged a transmission that was deemed un-repairable and was destined for the scrap heap.

Over the next year, as and when they could afford to buy the needed parts, they set about rebuilding the transmission in their basement flat, followed by dismantling it, and rebuilding it in the back of a car and then driving it to a port to transport back to NZ. It was sold before it arrived back on our shores!

The rest is history and here we are today 40 odd years later, representing an incredible stable of brands and products and as a key player in multiple NZ markets.
