About Us

In 1983, Clint and Dustin Johnson’s parents, John and Terri, opened Guaranteed Automotive & Transmission Service in Lafayette. Their father passed away in 2003, and now the brothers co-own the shop with their mother, Terri. From the 1980s through the early 2000s, we specialized in only transmission services.  In 2007, we expanded our automotive services to include complete general automotive repairs as cars were becoming more complex. Guaranteed Automotive & Transmission Service serves clients who have been with us for three generations. We truly have a heartfelt connection with our customers, and their continued loyalty means the world to us.

If you’re a vehicle owner looking for exceptional car repair and caring customer service in or around Lafayette, IN, choose Guaranteed Automotive & Transmission Service.
