Truck & Diesel Specialist in Mt Roskill, Auckland

Mt Roskill’s Truck & Diesel Vehicle Specialists

Galeeco’s Mt Roskill workshop is equipped and staffed to handle the most demanding diesel truck and fleet repair work in Auckland. While many mechanic shops focus exclusively on passenger cars, we have the tooling, diagnostic equipment and technical experience to work on:

• Heavy trucks – Hino, Isuzu, Mitsubishi Fuso, MAN, DAF
• Light trucks and vans – Ford Transit, Toyota HiAce, Mercedes-Benz Sprinter, VW Transporter
• Utes – Ford Ranger, Toyota Hilux, Nissan Navara, Mitsubishi Triton, Mazda BT-50
• Fleet diesel vehicles – courier fleets, trade fleets, government and council vehicles
• Specialty diesel vehicles — refrigerated trucks, tippers, tankers and service vehicles

Our diesel specialists are trained in the full range of modern diesel engine technologies – from DPF and EGR systems through to turbocharger diagnosis and high-pressure fuel injection service.

What makes Galeeco Mt Roskill different:

• ✅ Eaton Fuller Road Ranger rebuilds – in-workshop rebuilds of 9-, 13- and 18-speed RTLO-series gearboxes. Most Auckland options sell you a reman unit; we rebuild your own, which usually means less cost and less downtime.
• ✅ COF preparation that protects your ORS score – we pre-inspect, repair to standard, and get heavy vehicles through certification cleanly, so your Operator Rating stays strong.
• ✅ Make-specific diesel diagnostics — we read proprietary Hino, Isuzu and Mitsubishi Fuso ECU codes, not just generic OBD faults.
• ✅ Fleet scheduling built around uptime – planned, multi-vehicle servicing so repairs don’t become breakdowns.
• ✅ Heavy and light under one roof — the same shop does your Hino’s COF, your Ranger’s DPF, and your courier van’s WOF.
