Match the appointment to the work
Roadworthy currently lists three Miamisburg facilities whose official websites advertise transmission services. This collection separates a specialist’s published drivetrain coverage from general repair options; it is alphabetical, not a quality ranking. It does not include businesses merely targeting Miamisburg in their advertising.
- Brownies Independent Transmission, 128 Alexandersville Road: its official site describes automatic and manual transmission work, clutches and driveline components. Its published Miamisburg hours include Saturday morning. Confirm whether the initial visit is a diagnostic appointment and whether any proposed rebuild is performed at this location.
- Kiddle’s Auto, 308 Mound Avenue: the official site lists transmission repair alongside general vehicle services. Ask which transmission work it performs for your particular model and whether additional evaluation is needed before an estimate.
- Sam’s Automotive, 6015 Manning Road: the business advertises transmission repair and replacement, as well as clutch and differential work. Ask whether the recommended work is a repair, a replacement unit or a separate driveline repair.
Scope and locations checked against official websites September 19, 2026. No facility has confirmed availability or quoted a price to Roadworthy. See each listing below for its source links and contact details.
Three questions that make quotes comparable
- What diagnosis supports the recommendation, and what does the first evaluation cost?
- Does the quote specify repair versus replacement, the condition of any replacement unit, fluids, programming and other included work?
- What written warranty applies to parts and labor, and who handles a problem after pickup?
Use our diagnostic-fee worksheet before approving investigation, then our estimate comparison guide. Do not assume a fluid service resolves a reported shifting problem; ask the facility to determine the appropriate next step for your vehicle.
Widen the search when necessary
For other work, browse all Miamisburg facilities. If none handles your vehicle, the full transmission directory and Dayton-area community directory provide additional starting points. Call before arranging transport; these pages do not establish towing availability.
