Transmission Repair

The Importance of Your Car's Transmission

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.

When you press down on the brake pedal, the master cylinder pressurizes a system of hydraulic brake lines leading to each of the vehicle’s wheels, where brake pads or shoes press against a disc or drum and create the necessary friction needed to slow the vehicle to a complete stop. Over time, this friction and heat has the potential to wear down the brake shoes, brake pads, calipers, brake rotors, and other braking components. While the components comprising each brake system may vary, the warning signs for impending brake repairs are the same.

Automatic Transmission Repair

A transmission is responsible for transferring power from the engine to the drive wheels and helping the engine accommodate a range of speeds. An automatic transmission routes power from the engine to the drive wheels while shifting between gears automatically so you can concentrate on regulating power and speed. Automatic transmissions contain the following major components: a planetary gear unit, a hydraulic pump, and a torque converter. The primary difference between an automatic transmission and a manual transmission is the torque converter, which operates similarly to the clutch. The torque converter automatically adjusts to engine speed and supplies power to the wheels of the vehicle. Torque converters rely on transmission fluid to help lubricate internal gears and components, though transmission fluid also helps with the force and pressure needed for switching gears. Throughout an automatic transmission’s life, various maintenance services can help prevent major repairs and unexpected breakdowns while extending the life of your transmission.

Clutch Adjustment and Inspection

In a manual transmission, the responsibility of the clutch is to engage and disengage the transmission from the engine. A clutch in a manual transmission allows the engine to continue turning even when the vehicle is stopped. In an automatic transmission, this process is regulated by the torque converter and transmission fluid. The clutch operates two shafts, one in the transmission and the other in the engine, and uses friction to keep the transmission connected to the engine. If the clutch is engaged, the pressure plate pushes against a flywheel and joins the transmission to the engine. If the clutch is disengaged, the pressure plate pulls away from the flywheel, separating the transmission from the engine. The clutch makes switching gears possible. Some transmissions use hydraulic clutches while others use cable clutches. In both cases, routine clutch maintenance is required to keep all moving components operating efficiently. If you are concerned about the functionality of your clutch, be sure to contact us about a service.

Clutch Replacement

When a vehicle is running, the engine is always turning. The transmission connects to the engine and supplies power to the wheels, but this linkage cannot be constant, since a vehicle is not always moving. In a manual transmission, the clutch is used to engage and disengage the transmission and the engine. The clutch operates two shafts: one shaft connects to the transmission and the other connects to the engine. Clutches use friction to keep the transmission connected to the engine. When the clutch is disengaged, the pressure plate pulls away from the flywheel and separates the transmission from the engine. When the clutch is engaged, a pressure plate pushes against a flywheel and joins the transmission to the engine. In a manual transmission, a clutch allows your engine to continue spinning even when the vehicle is stopped. Switching between gears in a vehicle with a manual transmission is made possible by operating the clutch.

Manual Transmission Repair

Manual transmissions allow drivers to shift between gears manually while simultaneously regulating power and speed. Manual transmissions have a clutch, flywheel, gear selector fork, collars, gears, and shafts. A shaft supplies power from the engine to the transmission. The clutch is responsible for connecting and disconnecting the shaft from the transmission. The stick shift controls the gear selector fork by choosing gears. These gears and shafts are responsible for routing power from the engine to the transmission and to the drive wheels. Manual transmission fluid cleans the internal gears, shafts, bearings, and other components. Transmission fluid also helps to regulate the internal temperatures of the transmission. A manual transmission service will ensure that your transmission fluid is clean and the rest of the components are fit for operation.

Transmission Replacement

Whether your vehicle has an automatic or manual transmission, the responsibility of the transmission remains the same: route power from the engine to the drive wheels. Essentially, the transmission converts the RPMs of the engine into torque, which is transferred to the drive wheels of the vehicle. The transmission switches between a range of speeds by shifting gears as a vehicle speeds up and slows down. Transmission fluid acts as a cooling agent. This fluid lubricates the internal gears and prevents corrosion and rust while the transmission filter helps to remove contaminants from the fluid. The components inside manual and automatic transmissions may differ, but routine maintenance is all about keeping internal components moving and operating as they should. When the life of your transmission comes to an end, our service staff will replace your manual or automatic transmission with a quality aftermarket transmission that matches or exceeds the performance standards of the originally equipped transmission.

Benefits of Transmission Repair

A faulty transmission can negatively affect your vehicle’s performance. Symptoms of an impending transmission service include grinding gears, difficulty shifting, slipping out of gear, bucking, and hesitation. Even if your transmission is in neutral, excessive noise is a sign of transmission problems. In a manual transmission, a dragging clutch, or a clutch failing to disengage from the flywheel, is another sign of transmission issues. When this occurs, the clutch continues to spin with your vehicle’s engine, and a grinding noise will occur. A burning smell sifting through the air vents is a sign of burning transmission fluid and an overheating transmission.

Things that can negatively impact the life of your transmission include extreme driving habits, and excessive loads or heavy towing habits. Because of the necessary pressure and force provided by transmission fluid in automatic transmissions, old, dirty, and unchanged transmission fluid can cause performance issues. Regular transmission maintenance as indicated by your vehicle’s manufacturer can help prevent transmission problems, but if you experience any of the above warning signs of transmission trouble, contact us today about transmission repair.
