Continuing education is a must at 5th Gear. Our investment in our employees translates directly to the superior service you and your vehicles get at our facility.  5th Gear Automotive employs a broad range of diagnostic software and has priority access to industry- wide information on every make and model vehicle we service. We own and use over 10 different computer diagnostic scanning tools that plug directly into your vehicle to scan and diagnose any present issues.

Subscription-based online sources are also available at the fingertips of all technicians at any of the 6 PC stations throughout the shop. Owner Andy Eberstadt states that aftermarket service information providers, such as All Data, Mitchell, Identifix, and networking on iATN, all aid in troubleshooting. Andy and his staff also seek out technical service bulletins (TSBs) associated with the specific trouble code that the diagnostic scanning tools or online info databases may return for a specific issue he is trying to resolve.
