About Rosh Auto
Rosh Auto was founded with one mission – to connect drivers with discounted automotive parts, engine control modules (ECMs), and diesel auto parts in Springfield, MO that keep families on the road without breaking the bank. We recognized that car owners needed a trusted ECM shop in Springfield offering affordable ECU replacements, refurbished ECMs, and diesel truck parts, so we built a better way to serve them.
By eliminating unnecessary steps, we pioneered a process that delivers refurbished ECM modules, automotive ECU replacements, and diesel engine electronics directly from reliable engines to your vehicle. Our team is committed to making your ECM repair, ECU programming, and automotive diagnostics experience fast, affordable, and stress-free.
Rosh Auto is more than just an ECM supplier – we are a family-owned auto parts shop in Springfield, MO with over 30 years of generational knowledge. What started on a card table in our basement with a handful of diesel ECMs and fuel injectors has grown into a nationwide ECM parts shop trusted by drivers, mechanics, and trucking companies. Our very first shipment even left in an old printer box with a stick of Mentos inside – a small gesture to thank our very first customer.
Today, we continue to provide rebuilt diesel ECMs, aftermarket automotive ECUs, and diesel truck injectors with the same dedication and appreciation. Whether you need a semi-truck ECM replacement, a commercial truck injector repair, or a reliable ECM diagnostics shop in Springfield, Rosh Auto is here to help. Your vehicle matters to us – and so do you.
