Automatic Transmission Erratic Shifts

Jan 15, 2023

At Grafco Electric, we understand the frustration and inconvenience that can arise when your automatic transmission starts exhibiting erratic shift patterns. Unpredictable gear changes can make driving unsafe and hinder the overall performance of your vehicle. Fortunately, our team of experts is here to help you diagnose and address these issues effectively, providing reliable solutions to ensure your automatic transmission is operating at its best.

The Causes of Erratic Shifts

Erratic shifts in automatic transmissions can occur due to various underlying issues. Understanding these causes can help you identify and address the root problem more efficiently. Here are some common factors that can contribute to erratic shifts:

1. Low Transmission Fluid Levels

Insufficient fluid levels can hinder the smooth operation of your automatic transmission, leading to erratic shifts. Fluid leaks, improper maintenance, or a faulty transmission cooler can all contribute to decreased fluid levels. Regularly checking your transmission fluid and addressing any leaks or concerns promptly can help prevent this issue.

2. Worn-out Clutch Plates

Over time, the clutch plates in your automatic transmission can wear down, resulting in erratic shifts and slip during gear changes. This can be caused by excessive heat, inadequate maintenance, or regular wear and tear. Replacing worn-out clutch plates is essential to restore the smooth functionality of your transmission.

3. Faulty Shift Solenoids

Shift solenoids play a crucial role in facilitating the gear changes in your automatic transmission. When these solenoids become defective or fail, they can cause erratic shifts or prevent the transmission from shifting at all. Professional diagnosis and replacement of faulty solenoids are necessary to resolve this issue effectively.

4. Malfunctioning Sensors

Modern automatic transmissions rely on various sensors to monitor vehicle speed, throttle position, and other vital parameters for precise shifting. When these sensors malfunction or send incorrect signals, it can result in erratic shifts. Diagnosing and replacing faulty sensors is crucial to restore the proper functionality of your transmission.

Identifying Symptoms of Erratic Shifts

Recognizing the symptoms associated with erratic shifts can help you promptly address transmission issues before they worsen. Here are some common signs to watch out for:

  • Sudden and unexpected gear changes
  • Transmission slipping or jerking during gear shifts
  • Delayed engagement when shifting into drive or reverse
  • Reduced acceleration or power loss
  • Transmission overheating

Troubleshooting Erratic Shifts

If you're experiencing erratic shifts in your automatic transmission, there are a few troubleshooting techniques you can try before seeking professional assistance:

1. Check Transmission Fluid

Ensure that your transmission fluid is at the correct level. Refer to your vehicle's owner's manual for instructions on how to check and add fluid if necessary.

2. Address Fluid Leaks

If you notice any fluid leaks, have them repaired promptly to prevent further damage to your transmission and ensure proper fluid levels.

3. Test the Transmission Speed Sensors

Modern transmissions rely on speed sensors to monitor vehicle speed and adjust gear shifts accordingly. Consult your vehicle's manual or seek professional assistance to test and replace any faulty speed sensors.

4. Consider a Transmission Flush

Over time, debris and contaminants can accumulate in your transmission fluid, affecting its performance. A professional transmission flush can help remove these impurities and improve the overall functionality of your transmission.

While these troubleshooting techniques may be helpful, it's essential to consult a qualified technician for a thorough diagnosis and proper resolution of any erratic shift issues.
