Gear Up: Transmission Service at Gary Knurek GoodYear in Troy

March 11, 2020

The transmission system in your vehicle allows you to change gears. Lower gears are power gears. They get your vehicle moving and get it up hills. Higher gears get the vehicle up to speed and get it rolling faster. If you have a standard transmission, then you have to do the work of shifting gears yourself. But with an automatic transmission, the vehicle shifts gears on its own. It automatically starts out in low gear and automatically shifts to high gears as it gets rolling. Again, it will automatically shift to a lower gear to climb hills or when you need a burst of speed.

How does it know when to change gears? Today's automatic transmissions are computer-controlled. The computer gathers information about what the vehicle is doing and changes the gears as needed.

Automatic transmissions are becoming more sophisticated all the time. More gears, or “speeds,” are being added. Almost all vehicles have at least four speeds. Five or six is common. Some are even increasing to seven or eight – up to ten. Adding gears has a lot of advantages for Troy vehicle owners: it improves fuel economy and increases performance.

But there is a drawback for drivers in Troy: more gears equal more parts and a more complex transmission system. Plus, all those parts need to fit into the same space as older, less complex transmissions. This means that today's transmissions are engineered to much tighter tolerances. In other words, they demand meticulous care from Troy drivers. Transmissions are designed for durability. But that durability can be compromised if they aren't given proper care.

That's why changing transmission fluid is such an important part of preventive maintenance for vehicles in Troy. Transmission fluid lubricates the transmission and keeps it in good working order. But if the fluid runs low, transmission parts will wear out quickly or suffer damage due to increased friction. The transmission can even fail.

Dirty transmission fluid can clog the small passageways in the transmission, blocking lubricant from reaching all of its parts. Again, this can lead to increased wear, damage or failure.

New transmissions aren't cheap. Repairing them isn't cheap either. But changing transmission fluid is fairly inexpensive at Gary Knurek GoodYear in Troy. That's why responsible car care includes maintenance on the transmission system at Gary Knurek GoodYear. It doesn't take a genius to figure out that periodic fluid changes aren't just good auto advice, they actually pay for themselves by preventing transmission repairs.

Let’s Clear the Air

All of us want the air we breathe to be clean and free of pollution.

Theyre called catalytic converters, and while they will likely last you years on y... More
