Expert Transmission Overhaul Backed by ASE-Certified Precision

Your transmission is one of the most complex and critical systems in your vehicle. When the transmission starts to fail, you need a team that knows how to tackle the issue with confidence and clarity. At Jefferson Auto Service, our technicians don’t guess. We run a full Digital Vehicle Inspection (DVI), test, diagnose, and walk you through exactly what’s going on before we turn a wrench. Whether you’re dealing with slipping gears, delayed shifting, or fluid leaks, our team is trained to handle domestic, foreign, and hybrid transmissions with precision.


We work on all major domestic makes and models—especially the Big Three: Chevy, Ford, and Dodge. We’re in the heart of the Motor City, after all. We also service fleets, trucks, and commercial vans that demand high-mileage reliability. Need a band-aid to get to work or a full overhaul for your kid’s first car? We’ll walk you through both options and help you decide what’s right for your situation and budget.

At Jefferson Auto Service, we start every job by asking you what outcome you want. Then we build a repair plan around it. Our goal is to show you your options so you can take appropriate action around your vehicle’s transmission needs. No pressure. Just facts. Check this review out:
