DESCRIPTION OF DIFFERENTIAL REPAIR
The differential is responsible for transferring engine power to the wheels. It also compensates for and adjusts to the differences in wheel speed as your vehicle moves through turns. When your vehicle navigates a turn, the inside wheel turns slower than the outside wheel, which has to turn faster in order to keep pace with the inside wheel. The differential allows the wheels to turn at different speeds while maintaining control. A vehicle without a differential would hop and bump along the pavement for an unstable, shaky ride. Four wheel drive vehicles are equipped with a differential in front and back, while rear wheel drive vehicles are equipped with a differential in back. A front wheel drive’s differential, called the transaxle because of the functional combination of the front axle and transmission, is located between the front wheels. All-wheel drive vehicles are equipped with a differential between both the front and rear wheels with a transfer case between them. The case adjusts for speed differences between the front and rear wheels. In all vehicle applications, the differential is primarily responsible for routing and regulating power between wheels.
DESCRIPTION OF ENGINE DIAGNOSTICS AND PERFORMANCE
Every vehicle built since 1996 has been equipped with an On-Board Diagnostics System that monitors engine performance. Discrepancies in performance levels are reported through your vehicle’s computer system. Once the “check engine” or “service engine” light is displayed, your next step should be to seek out an engine diagnostic service or an engine tune-up. Engine diagnostics allow our staff to gather helpful information about the operating condition of your engine. The insights obtained during an engine diagnostic will determine the extent of suggested engine repairs. The most common diagnostic trouble codes are generated in response to malfunctions in the powertrain. Ultimately, regular engine tune-ups are necessary to optimize engine performance. A tune-up is also one of the most effective ways to prevent unexpected engine trouble. During an engine tune-up, our staff may replace the spark plugs, spark plug wires, air filter, fuel filter, and distributor cap and rotor in your vehicle. Our experts will also check emission levels, fuel lines, and belts and hoses. Engine diagnostics and regular engine tune-ups can help extend the life of your vehicle and improve the health of your engine.
DESCRIPTION OF TRANSMISSION REPAIR
The transmission is the link between the engine and the wheels of your vehicle. Whether you drive a manual, automatic, or semi-automatic vehicle, the transmission plays a crucial role in the performance and reliability of your vehicle. The transmission keeps engine output matched with speed and load conditions. Because engines operate at high rotational speeds, the transmission reduces engine output speed and transmits torque through the differential, driveshaft, and wheels. As engine speed varies, the transmission switches between the gears that influence the amount of torque applied to the wheels. Transmission fluid performs a variety of duties, depending on the type of transmission. Transmission fluid acts as a cooling agent and protects the transmission by lubricating the internal gears and preventing corrosion and rust. In a manual transmission, clutches and gear shifts provide pressure and force—like engagement and disengagement—while in an automatic transmission, transmission fluid provides these same operational functions of force and pressure.
