Roswell's cars are keepers

A 1980s neighborhood is exactly where rebuilds make sense.

Nearly half of Roswell's housing — 47.8% — was built between 1970 and 1989, a third of it in the 1980s alone. That's the closest match to East Cobb anywhere, and it means the same thing here as there: long-tenured owners, paid-off vehicles, and a strong case for fixing the car you trust instead of financing one you don't. With 15.6% of Roswell aged 65+, we also hear the retiree version often: "I'm not buying a new car — just fix this one right."

That's the job we're built for. A rebuild here isn't a swap to an assembly-line unit — it's your transmission, taken apart on our bench, rebuilt with hand-picked parts, road-tested, and warrantied for 2 years / 24,000 miles.

Get a second opinion before a Roswell rebuild

Roswell has good shops — and dealers quick to quote whole transmissions. Before you commit thousands, a 19-minute drive gets you a free road test, scan, and lift inspection from the shop other shops send transmissions to. If the first quote was right, we'll confirm it; if not, you just saved real money. How the free second opinion works →

Fulton emissions, same story

Fulton County requires the annual emissions test, and a transmission code that lights the check engine light is an automatic failure. If a powertrain code is blocking your tag, read this first.

Mountain Park neighbors, you too

The little city of Mountain Park, tucked off Mabry Road between Roswell and Woodstock, is actually closer to us than Roswell's center — about 15 minutes.
