Transmission Replacement

At Cottman, we fix transmission problems; it’s been the hallmark of our business model since 1962. That usually means repairing or rebuilding your transmission. But sometimes a repair or a rebuild just isn’t your best choice. Sometimes a better choice is to replace your transmission with a remanufactured one, or “reman.”

For example, maybe your transmission is too damaged to repair it at a reasonable price. Or maybe the parts aren’t available. Then again, maybe a reman will just provide better warranty coverage for your particular situation.

Whatever the reasons, at Denver Cottman, we sometimes recommend transmission replacement instead of a repair or rebuild. Naturally, we’ll always explain the reasons to you, and show you why replacing your transmission is a better option for you. In every case, the final choice will be yours.

Rest assured that, whether you end up with a repair, a rebuild, or a reman, at Denver Cottman you’ll always receive a complete diagnosis, and we’ll always stand behind our repair, whatever they entail. And we promise you that, when you bring your car or truck to Denver Cottman, you’ll never pay for a transmission unless you actually need a transmission. That’s our promise to you.
