Customer Review

I am not a current customer but brought my dad's vehicle in for an oil change cause he has always used these guys for any service work that was needed and was simply blown away with the kindness that they showed me. They really do care about each customer that they have and in today's world that is rare. Would definitely recommend these guys for everything!!!!!

When driving around town, your vehicle's engine needs clean air to burn the fuel – and it needs a lot. In fact, a typical vehicle needs about 216,000 gallons of air for every tank of gas. All that air passes through a filter that catches the dust and dirt. Eventually, the filter gets completely full, and because the filter can only hold so much, dirt starts getting through. At National Brake & Muffler in Griffin, we want to help you get the best air quality in your vehicle, but first, we want to explain the process of where this dirty air is going.

Transmissions are complicated and intricate pieces of equipment. Many general mechanic shops won’t touch a transmission, if it’s anything more than simply installing a new one. Transmissions are one aspect of a vehicle that even experienced mechanics often don’t dare delve into, and is easily the most mysterious and misunderstood system in the automotive world. You need a shop that you can trust to perform the best work on whatever your transmission may be in need of.
