Do You Take Walk-In Customers?

We often get asked if it’s better to make an appointment before visiting our shop in downtown Modesto. The truth is most of our customers prefer to schedule appointments, but we do accept walk-in customers—especially if it’s an emergency. In general, it is recommended you book an appointment first. That will ensure we have time and space dedicated to your service visit. We can get your vehicle into our shop quickly for a free initial inspection, road test and computer diagnostics. Then, we can present you with a detailed inspection report to let you know our recommended repair or maintenance services, if any are required.

Ready to Serve You

We have a large transmission repair facility with several bays and heavy duty lifts available for service. Still, we can be very busy some days and that’s why it helps to book an appointment in advance. You can call us anytime at 209.526.1909 or use this link to schedule your appointment online.

Otherwise, you are always welcome to come in during our open hours Monday through Friday. We will do our best to squeeze you in as quickly as possible and take care of your important transmission needs.
