What symptom may occur if clutch components are worn in an automatic transmission?

• A. Improved fuel economy
• B. An increase in overall vehicle speed
• C. Transmission judder during gear shifts
• D. Transmission shifts without any noise

Answer: (C)

When clutch components in an automatic transmission are worn, one of the key symptoms that may become evident is transmission judder during gear shifts. This phenomenon occurs because worn clutches can lead to insufficient engagement or disengagement between the transmission components, causing the vehicle to shake or hesitate when shifting from one gear to another. Judder typically results from the loss of smooth engagement, which is critical for the seamless operation of an automatic transmission. Factors such as worn friction plates, damaged springs, or insufficient hydraulic pressure can all contribute to this uncomfortable sensation. It indicates that the transmission is struggling to shift efficiently, which could lead to a more severe performance issue if not addressed. Other symptoms such as improved fuel economy, an increase in overall vehicle speed, or shifts without any noise are not typically associated with worn clutch components. In fact, worn components tend to lead towards more issues, including decreased fuel efficiency and erratic shifting behavior, rather than improvements in these areas.
