Three generations.
One roof.
The Koulouvaris family has kept South Florida shifting for over 40 years — a true transmission shop where the same hands that build a 1000-HP unit fix the family minivan.
A true transmission shop since 1983
Number One Transmissions opened its doors in Oakland Park in 1983, and a transmission is all we’ve done ever since. Three generations of the Koulouvaris family have diagnosed, repaired, rebuilt, and shipped transmissions from this one shop — not a franchise, not a chain, and not a general repair shop that farms the hard jobs out.
That focus is the whole point. When a transmission is all you do, all day, you see every failure a hundred times over — and you fix it right the first time. It’s why drivers from Fort Lauderdale to West Palm Beach, and from Miami up through the Keys, bring their cars, trucks, and fleets to us, and why we build and ship rebuilt units nationwide.

What 40+ years has taught us
The reputation we’ve built in Oakland Park comes down to a few simple things we don’t bend on:
- Diagnose first, quote second. Free diagnostics and an honest, written estimate before any work begins — the price we quote is the price you pay.
- Only the work you actually need. If it’s a repair, we won’t sell you a rebuild. If it’s not the transmission at all, we’ll tell you.
- Real expertise you can verify. ASE-certified, licensed & insured, and A+ accredited with the BBB.
- We stand behind it. A 1-year / 12,000-mile warranty on every repair and rebuild, since 1983.
- We give back. A special discount for veterans and first responders — just ask.

From a quick fluid service to a four-digit-horsepower build, it’s all done in-house:
