  • Everything you need to know about transmission sensors!

    Our Joppatowne drivers have been experiencing issues with their transmissions and there are a few things that we here at Joppa Transmission & Auto Service 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 Joppatowne 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 Joppa Transmission & Auto Service, 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. 

  • If you see steam, pull over!

    Something will go wrong with your car, truck, or SUV eventually. The important thing is knowing what to do, and how to deal with it. Just knowing what to do in a situation often means the difference between a quick repair and thousands of dollars worth of work. If you see steam coming from under the hood, it’s important to deal with it appropriately and quickly. Here’s what’s going on, and what to do, from Joppa Transmission & Auto Service in Joppatowne, MD.

  • Reduce Noise and Increase Fuel Mileage

    city of drivers with smog

    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.

  • Sometimes it is obvious, others we have to hunt for it!

    Here at Joppa Transmission & Auto Service in Joppatowne we often do diagnostics and sometimes the problem is obvious after hooking the car up to the computer and reading the codes.  However, sometimes it isn't obvious during a test drive or after hooking it up to all those computer programs!  You know there is a problem and a Check Engine Light is on with the fleet customer telling you the car has been having issues starting and the light has been going off and on depending on several factors.  No pattern, no simple answer but the problem becomes obvious when you start following the "threads of the issue" thanks to all that ASE Technician training.
