AW55-50SN Transmission Car Shakes

Introduction

The AW55-50SN is a five-speed automatic transmission used in various vehicles, including the Chrysler Sebring, Dodge Stratus, and Jeep Liberty. It is known for its smooth shifting and reliability, but it can sometimes develop problems that can cause the car to shake.

Causes of Car Shaking

There are several potential causes of car shaking when the AW55-50SN transmission is engaged:

1. Low Transmission Fluid: This is the most common cause of car shaking with the AW55-50SN transmission. When the transmission fluid level is low, it can cause the transmission to slip and shudder, which can lead to shaking.
2. Dirty Transmission Fluid: Over time, transmission fluid can become contaminated with dirt, debris, and metal shavings. This can cause the fluid to lose its lubricating properties, which can lead to friction and shaking.
3. Faulty Torque Converter: The torque converter is responsible for transferring power from the engine to the transmission. If the torque converter is faulty, it can cause the car to shake, especially at low speeds.
4. Internal Transmission Problems: In some cases, car shaking can be caused by internal transmission problems, such as worn gears or broken bands. These problems can be more difficult to diagnose and repair.

Diagnosis

Diagnosing the cause of car shaking with the AW55-50SN transmission can be challenging. It is important to have the transmission inspected by a qualified mechanic to determine the underlying cause. The mechanic will likely perform the following tests:

• Inspect the transmission fluid level and condition
• Test the torque converter
• Inspect the transmission pan for any signs of metal shavings or debris
• Perform a road test to observe the car’s shaking

Repairs

The repairs for car shaking with the AW55-50SN transmission will depend on the underlying cause. In most cases, the repairs will involve replacing the transmission fluid, torque converter, or other faulty components. In some cases, the transmission may need to be rebuilt or replaced.

Prevention

There are several things you can do to prevent car shaking with the AW55-50SN transmission:

• Keep the transmission fluid clean and at the correct level: This is the most important thing you can do to prevent car shaking. The transmission fluid should be changed every 30,000 to 60,000 miles, depending on the severity of driving conditions.
• Avoid hard acceleration and shifting: This can put extra strain on the transmission and lead to premature wear and tear.
• Have the transmission inspected regularly: A qualified mechanic can check the transmission fluid level and condition, and perform other tests to ensure the transmission is in good working order.

Conclusion

Car shaking with the AW55-50SN transmission can be caused by a variety of factors. It is important to have the transmission inspected by a qualified mechanic to determine the underlying cause. In most cases, the repairs will involve replacing the transmission fluid, torque converter, or other faulty components. By following the preventive measures outlined above, you can help to prevent car shaking and keep your transmission running smoothly.
