Transmission Rebuilds

If it’s on the road long enough, eventually every transmission will need to be rebuilt. Its components are designed to wear out over time; it’s a necessary part of the transmission’s operation.

Hopefully yours won’t wear out for many years. But when it does, there’s no better place to bring your transmission than Cottman Transmission of Denver.

Why Cottman? Because even our name says “transmission.” We’ve been specializing in rebuilding transmissions since the first automatic transmissions began rolling off the assembly line. And we’ve built our reputation by providing quality rebuilds at a terrific price.

At Cottman, we don’t just replace the worn out parts. We build in the very latest updates, to bring your transmission beyond like-new performance. We use the finest parts available, and make sure that every transmission we rebuild is set to the “sweet spot,” where it can perform at its very best and keep performing that way for miles.

Of course, not every transmission problem needs a rebuild. Sometimes what seems like the transmission can be something else entirely. That’s okay, because our technicians are up on the latest diagnostic procedures, so you can be sure that, when you bring your transmission problem to Cottman, you’ll never pay for a rebuild unless you really need it.
