About Us

 Sonamatic Auto Center opened it’s doors in 1955.  Thanks to many loyal customers and employees we have continued to grow from a 1 bay shop with 2 employees to a 14 bay shop with 10 employees. Over the years we have based our reputation on quality and integrity and value.   When we first opened are doors we specialized in automatic transmissions.  As time went on and the shop expanded in size we became, a full line repair center with auto transmissions still being one of our specialties. 

In our earlier years, Snap On Tools approached us to run clinics on how to service and adjust automatic transmissions and how to test and recharge Air Conditioning systems. 

This was great because we got to know many good repair shops, their owners and also their employees.  Today, many are still referring work to us they don’t do.   We have always prided our selves with fixing the hard to find problems by having the latest in test equipment  and highly skilled repair technicians.

Most of our technicians have been with us from 10 to 40 years.  Some of them being ASC Gold Star Master Certificated.

Our employees don’t work on commissions.  Commission work can lead to unnecessary repairs and poor quality.  If you are having problems getting it fixed the first time, give us a call.
