Truck & Auto Transmission Repair Service at Fisher's Tire & Service | Pensacola, FL


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.

Benefits of Transmission Fluid Exchange

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.

Automatic Transmission Fluid Exchange

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.


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.


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.

Benefits of Differential Repair

Whether your car or truck has four-wheel drive, front wheel drive, or rear wheel drive, your vehicle has a differential that experiences heavy wear and tear. When scheduling a differential repair service, you should consider where you drive most often and how much time your vehicle spends traversing particular types of terrain. Tougher terrain—like dirt roads, unpaved or gravel roads—and extreme driving can have a heavier impact on the life of your vehicle’s differential. Maintenance for differentials will differ from vehicle to vehicle. As part of your normal car maintenance schedule, a differential fluid change can positively impact the safety and health of your vehicle. Noise coming from your vehicle’s differential can be a sign of insufficient lubricant or worn gears and bearings due to regular wear and tear. At the first sign of trouble, contact us so we can quickly diagnose and correct the issue.

Differential Fluid Change

Differential fluid lubricates the differential in all-wheel drive (AWD), four-wheel drive (4WD), rear-wheel drive (RWD), and front-wheel drive (FWD) vehicles. In most cases, front-wheel drive vehicles have a transaxle instead of a separate differential, but there are some instances where FWD vehicles have a stand-alone differential. The purpose of the differential is to deliver power to the wheels while allowing them to turn at different speeds. As your vehicle completes a turn, each wheel covers a different distance. The two wheels on the inside of the turn travel a shorter distance than the two wheels on the outside of the turn. Similarly, the two front wheels travel a different distance than the two back wheels. The differential allows your vehicle to make turns smoothly despite these differences, and differential fluid keeps the moving parts of the differential lubricated. Your differential needs clean differential fluid to ensure a smooth ride at all times.


Differential Service

Many vehicles need a properly working differential system for the smoothest ride possible. While all vehicles have some variation of a differential system, the location of the differential depends on the drive type of the vehicle. The differential system delivers power to the wheels while allowing the wheels to turn at different speeds. As your vehicle maneuvers through a turn, each wheel on the car travels a different distance. The two wheels on the outside of the turn travel a farther distance than the two wheels on the inside, and the back wheels cover a different distance than the front wheels. The differential permits the vehicle to complete turns easily despite these differences. Differential fluid keeps the differential system running smoothly by reducing heat and resistance caused by moving parts.
