What Causes Automatic Transmission Gear Failure?
2 Answers
Automatic transmission gear failure may be caused by the following reasons: Issues with the automatic transmission: Internal components of the automatic transmission may be faulty, requiring repair of the gear lever assembly. During gear shifts at low speeds, the clutch must fully disengage to smoothly engage the corresponding gear. Faulty solenoid valve or brake control: If the solenoid valve in the automatic transmission fails or the brake controller malfunctions, the solenoid valve needs to be replaced. Do not force the gear lever if it cannot be moved. Low vehicle temperature: Insufficient lubrication of the transmission fluid can cause gear failure. If the transmission makes a gear grinding noise when attempting to engage reverse gear while stationary, it indicates incomplete clutch disengagement. The issue can be resolved after repairing the clutch.
I've been driving for years, and automatic transmission gear failure has given me headaches several times. The most common issue is with the transmission fluid—low levels or dirty fluid can cause the hydraulic system to jam, leading to gear shift failure. It could also be due to faulty electronic components, such as malfunctioning sensors or loose wiring, which disrupt signal transmission. Mechanical parts like the shift linkage or solenoid valves failing can also cause this problem. In vehicles with onboard computers, incorrect software updates or bugs can interfere, making gear shifts sluggish. Additionally, improper operation, like shifting too quickly or driving without warming up the car, can temporarily cause failure. It's advisable to check fluid levels and quality during every maintenance service. If you notice abnormalities like delayed shifting, don't push it—stop the car immediately and call a tow truck to a professional repair shop. Safety comes first, and staying vigilant can prevent major issues.
