Transmission Repair Backed Nationwide

When you have a major transmission repair done at Jim’s Transmission Service, you’re not just covered here in Sioux Falls.

Qualifying repairs are backed by our ATRA Nationwide Warranty — up to 36 months or 100,000 miles.

If a covered warranty issue occurs while you’re away from home, warranty service can be performed through ATRA’s nationwide network of more than 3,000 participating transmission repair shops.

That means you can travel with confidence knowing your transmission repair has support available across the country.

Got an extended warranty and a transmission problem? We can help with more than just the repair.

Jim’s Transmission Service works with many extended warranty companies, and we can handle the claim process for you. We’ll diagnose the problem, document what’s needed, provide the estimate, communicate directly with the warranty company and work through the authorization process.

That means fewer phone calls and less hassle for you.

And remember — a transmission problem doesn’t automatically mean you need a new transmission or a complete rebuild. Many of the vehicles we diagnose need something less.

That’s why we diagnose first.

Why bring your vehicle to Jim’s Transmission?

Because a transmission problem doesn’t automatically mean you need a new transmission — or even a rebuild.

At Jim’s Transmission, we specialize in transmissions. That means our first job is figuring out exactly what’s wrong and then determining the best way to fix it.

Sometimes it’s a complete rebuild. Sometimes replacement makes more sense. And sometimes what feels like a major transmission failure turns out to be something that can be repaired without doing either.

That’s why the diagnosis matters.
