Gear Up: Transmission Service at John’s Auto Care in Boulder

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 four at least speeds. Five or six is common. Some automobile manufacturers are even increasing to seven or eight – up to ten. Adding gears has a lot of advantages for Boulder motorists: it improves fuel efficiency and increases performance.

But there is a drawback for Boulder car owners: more gears equals 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 Boulder car owners. 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 a vital part of preventive maintenance for Boulder drivers. 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 pricey 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 for Boulder auto owners at John’s Auto Care. That’s why responsible car care includes maintenance on the transmission system at John’s Auto Care. 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 expensive transmission repairs.
