Operating an engine through the transmission

used cars in Modesto

The transmission system is an important and expensive component in any vehicle. It enables the engine to perform within allowable parameters of power output, beyond which it would be destroyed. Understanding the transmission requires some basic knowledge of how the combustion engine works. The combustion engine outputs power in cycles known as revolutions per minute or rpm. Every engine can run up until a maximum number of rpm above which the engine would blow up. The transmission allows the engine to operate at an acceptable rpm by providing gear ratios for used cars in Modesto.

Decelerating:

When accelerating, the engine rises towards its maximum rpm. The transmission engages a ‘harder’ gear which causes the engine to restart its revolutions from a lower speed.  When decelerating, the softer gears are engaged to prevent the engine speed from dropping too low.  A good illustration can be drawn from mountain bikes. Assuming your legs are the engine, you engage easier gears when starting off or climbing to make acceleration easier and tougher ones for when you are in motion and want to accelerate. Matching your load (terrain) and speed to the right gear enables you to use energy more efficiently. This principle is similarly used in car transmissions.

Automatic transmission:

Manual transmissions have declined over the years to under 3.9 percent of cars sold in 2013 as a result of advancements in automatic transmission systems. Packing more gears and driver customizable algorithms for the rootle response, automatic transmission systems are able to shift quicker, smoother and in many cases, provide better fuel mileage than manual transmissions. A transmission system has multiple moving parts in contact. Transmission fluid is used to dissipate heat and reduce friction caused by this constant movement. The fluid gets degraded over time and needs to be replaced. Our highly trained team of car service technicians for used cars in Modesto will bring years of experience in servicing car drive trains to your vehicle.

Transmission system:

There are a number of tell-tale signs which can warn you of impending danger in your car’s transmission system. The first is a check engine light on your dashboard. This is not specific to transmission problems but should light up when the system has an issue. If you notice a strong, burning smell inside your car, which some wrongly refer to as clutch, which most likely suggests a worn transmission system.  Another symptom of transmission problems is when gear shifts are rough or jerky even when engaged properly by the driver. Lastly, abnormally low acceleration and leaking oil could also be an indication that your car’s transmission needs attention.
