Automotive Mechanical Transmission and Axle Service
The modern automatic transmission is the most complicated mechanical component in today's vehicle. The automatic transmission contains mechanical systems, hydraulic systems, electrical systems, and computer controls that work together to power the engine to drive the wheels. With so many parts working together, this can lead to your transmission needing special attention.
Transmission maintenance leads to a longer vehicle life. Typically trouble with the transmission starts from overheating. Stop-and-go traffic, heavy pulling, struggling in the snow, hot weather, and racing can cause your transmission to overheat. At higher temperatures the transmission fluid burns. Your vehicle loses lubrication and deposits inside the transmission increase. We recommend that you take your vehicle to a service technician as soon as you believe your vehicle is having transmission problems.
To prevent your transmission from damage:
- Check your parking space for leaks regularly. If you notice fluid deposits under your car, have one of our technicians inspect it right away.
- Check the transmission fluid levels and condition. Change it when necessary.
- Make sure you use the correct transmission fluid as specified in your owner's manual.
- Make sure to stop your vehicle before shifting into reverse or park.
- Always hold the brakes down when shifting from park.
Paying attention to your transmission will help increase the lifespan of your vehicle, save money on costly repairs, ensure smooth shifting, extend your transmission fluid's life, and help prevent leaks.
Axles are extremely important to your car. They are on par with brakes and tires when it comes to the safety of your vehicle.
Axles connect to the wheels and they bear the weight of your entire vehicle. They also may help drive your vehicle, and in most cars are an integral part of the steering system.
Today, most axles are split axles, which means the wheel on each side is attached to a separate shaft. This allows independent suspension of the left and right wheels, and therefore a smoother ride. It also permits the left and right wheels to rotate at different speeds as the automobile turns, improving traction and extending tire life. This is what’s known as the differential.
Many cars combine the transmission and the axle to create the transaxle. In rear-wheel vehicles, the engine is connected to a driveshaft which turns the drive axle in the back of the car.
The axle is connected by the wheel to the CV joint. This is covered by a CV joint boot, a protective flexible covering. It’s important to make sure the boot is not cracked or leaking. This can cause brake fluid to leak out, possibly resulting in serious damage to the CV joints.
