Quality Transmission Repair and Auto Repair

In Cedar City, Utah

Different Name, Same Great Service!
"St. George Transmission in Cedar City? Sounds a little funny to me!" Hey, we agree... Since 2009 Cedar Performance has done business as a satellite location of St. George Transmission. Over the years we have endured no small amount of confusion and sometimes, even a little resentment due to our "St George" name. Those of us that work at the Cedar location have always disliked it ourselves; after all, we are all from Cedar and are part of this great community too. Well, all that has now changed. We have heard you Cedar City and are ready to announce a name that better suites our location!


We are proud to announce that as of July 18, 2016 we will be doing business as Cedar Performance Transmission and Automotive. Yes, the name is kind of long but we needed something that let people know that while we specialize in transmission and drivetrain repair, we are also a full service auto repair facility, specializing in a variety of other repairs. Name changes are always confusing and can leave a person wondering if all the people they came to trust are now gone. We totally understand so here is what you need to know...

-Nothing has changed other than the name. We are still the same people that have been serving you since we opened our doors in 2009 from the owner on down and we will continue to serve the Cedar community the way we always have. We look forward to proudly answering the phone as Cedar Performance and hope you will continue the patronage we have enjoyed since we opened our doors.

Thanks, from all of us here at Cedar Performance!
