A mechanic for Happy Valley and the southern foothills
Happy Valley sits up in the southern foothills, by the reservoir and alongside Aberfoyle Park, Flagstaff Hill and Chandlers Hill. Our Lonsdale workshop is a short drive down the hill, by way of Reynella.
Living in the foothills means every trip starts or ends with a climb, and that puts brakes, cooling systems and automatic transmissions to work every day. We look after all 3 as part of a proper service, and we explain what we find with photos so you can plan ahead.
We service family cars and SUVs, and we're a diesel specialist for the utes and 4WDs that head out of the hills for weekends away.

Brakes, transmissions and servicing for foothills driving
Hills driving asks more of the parts that control speed and heat, so these are the jobs Happy Valley drivers book with us most:
- Brake repairs: pads, rotors and fresh fluid for confident stopping on the descents.
- Automatic transmission servicing and gearbox repairs for smooth shifts on the climbs.
- Log-book servicing with the cooling system checked, keeping your new-car warranty in place.
- Dyno tuning for diesel utes and 4WDs that tow up the hill.
