Transmissions are complex pieces of equipment. Systems and components rely heavily on one another, and everything needs to be in working order for proper function. When one thing fails, there’s a snowball effect, and malfunctions and damages begin to occur. What can you do to make sure you keep it working? At National Brake & Muffler in Griffin, GA, we want to help when you need it, but we also want to teach you how to maintain your vehicle on your own. Good maintenance is the single largest contributing factor to how long your transmission will last and how well it will continue to work. Here are a few key points on maintenance from the National Brake & Muffler technicians.

You probably already know how to check your oil, and when to change it. Checking and maintaining transmission fluid is something people tend to understand far less about, however.

Prevention is better than cure. You've probably heard that said plenty of times. The phrase is most often used to talk about health and medicine, but it is just as valid to apply it to vehicles. It's great if your problem can be sorted without much trouble, but even better not to have a problem in the first place. This is especially true when it comes to your vehicle's transmission, as this can be one of the more specialized parts to repair. Not all transmission problems require an extensive overhaul, but they will all cause at least some trouble and inconvenience. Avoiding transmission problems is clearly preferable to even the problems that are quickest and cheapest repair. This is why it is important to ensure you take good care of your transmission. This will help prevent problems and keep it working smoothly. Ideally, it will mean that it doesn't develop any faults at all. Even if it does eventually go wrong, however, it is entirely possible that good care will mean the fault is less serious and easier to repair than it would have been otherwise. Here's some insight on how to prevent problems from our team here at National Brake & Muffler.

Manual transmissions have been around for a long time and if you have ever driven a manual you know how exciting they can be. Manual transmissions have also been referred to as standard transmissions, stick shifts, manual gearbox, or a simple gearbox.

So what do you know about manual transmissions; where did they come from, and how do they work? National Brake & Muffler in Griffin, GA knows, and now you will too.
