    Our Flagstaff drivers have been experiencing issues with their transmissions and there are a few things that we here at TAG Automotive Repair feel are important to know so that you are more comfortable and confident if you are, indeed experiencing a transmission problem of any kind. First, if you drive a vehicle manufactured in the past few decades, there’s a good chance your transmission has a variety of sensors attached to it which monitors all kinds of things - fluid pressure, vehicle speed, temperature, air intake at the engine, and so on.  The first thing to check is your Transmission Sensor, which is a much more affordable fix than replacing your transmission!

  • Have you checked your battery? If it looks like this - It's bad!

    When you are having trouble with your car or truck starting and you open the hood up to take a peek to see this....you'll see what an overly corroded battery looks like. This happens naturally over time on vehicle battery terminals.  If you are like 99% of normal Flagstaff drivers, you don't check your oil or your battery so you don't keep an eye on the amount of corrosion that's building up on your car or truck battery.  Here at TAG Automotive Repair, we do and there are solvents that we can use here in the shop during a battery maintenance service that will help slow the corrosion process but nothing that can prevent it 100%. Way before it gets to this point, we will be suggesting you consider replacing the battery.

  • Recognizing Flood Damage When Buying A Vehicle

    Unless you are confident in your abilities as an automotive mechanic, there is really only one rule when purchasing a flood-damaged vehicle: don’t do it. Unfortunately, sometimes sellers aren’t particularly straight-forward with their used cars. Many will try to hide the fact that it’s been damaged by floodwaters at all or try to convince potential buyers that the car is in fact fine. “It has gone months with no issues” or “technically it is flood-damaged but” are two red flags, and while it isn’t impossible for a flood car to be fine, it’s altogether a good idea to stay away.
  • Reduce Noise and Increase Fuel Mileage

    While your exhaust system helps reduce noise output from your vehicle, it also significantly reduces harmful emissions from being released into the air. When your muffler and exhaust system are functioning properly, it significantly reduces your vehicle's harmful impact on the environment. It also significantly improves the functionality of your vehicle and improve fuel mileage for your car, truck, SUV or Jeep.

    An exhaust system is made up of numerous parts that work together to rid your car of the exhaust gases that are created during the combustion cycle, as your engine burns fuel. Each part of your exhaust system has an important role to play in removing exhaust gases away from the engine as quickly as possible, allowing another cycle of combustion to begin. The more quickly and efficiently an exhaust system does this the more efficiently an engine can run. The main parts of an exhaust system are an exhaust manifold, catalytic converter, oxygen sensors, exhaust pipes, and the muffler.
