1-year / 12,000-mile on every repair and rebuild

Whether we replace a single solenoid or rebuild your transmission from the case up, the work is covered by our 1-year / 12,000-mile warranty. It isn’t a special upgrade or an add-on you have to ask for — it comes with every repair and rebuild we do.

A warranty is only as good as the shop behind it. We’ve been a family-owned transmission shop in Oakland Park since 1983 — three generations of the Koulouvaris family — and we intend to be here for a long time. That’s the real reason we stand behind our work: our reputation lives on every transmission that leaves the shop.

Honest estimates. The price we quote holds.

The warranty starts before the work does. We diagnose for free, explain what we found, and give you a written estimate for the right fix — a repair if a repair will do it, a rebuild or replacement only if it’s truly needed. The price we quote is the price you pay.

Want the details? Ask us.

Every vehicle and every job is a little different, so we don’t try to cover every situation on a web page. If you want to know exactly what’s covered on your job, ask us — we’ll put the terms in writing on your estimate, so you know where you stand before any work begins. The same goes for rebuilt units we sell and ship: ask about the terms when you order.

If a problem comes back

Call the shop. Seriously, that’s step one. Talk to us at (954) 535-9393, tell us what the vehicle is doing and when it started, and we’ll take it from there. Have your paperwork handy if you can, and if it’s safe to drive, we’ll get you scheduled to bring it in so we can look at it. If it isn’t safe to drive, tell us that too and we’ll talk through the next step.
