Cedar Transmission & Automotive

Cedar Transmission & Automotive (also known as Cedar Performance) is a locally owned transmission rebuilding, drivetrain, and full-service automotive repair facility located at 1130 N Main St in Cedar City, Utah, serving drivers, truck owners, and fleets across Iron County.

Locally Owned Drivetrain and Auto Repair Expertise

The shop at 1130 N Main St first opened in 2009 as the Iron County branch of Dave Jeppson's 1992 St. George transmission business. In 2017, longtime shop technicians Joe Mower, a master transmission rebuilder with more than 20 years of experience, and Bill Overson, Co-Owner and Manager, purchased the facility and established Cedar Transmission & Automotive as an independent Cedar City business. Located on North Main Street directly across from the Cedar City KOA, the shop serves both local commuters and interstate travelers along the I-15 corridor.
