What are the common faults of Lexus CVT transmission?
2 Answers
Common faults of Lexus CVT transmission include jerking and impact, vibration, abnormal noise, delayed gear engagement, slow acceleration, dashboard warning lights, and failure to accelerate. Below is relevant information about Lexus vehicles: 1. Causes of faults: Most Lexus transmission faults are caused by damage to internal components such as the steel belt, pressure cylinder, oil pump, valve body, and input shaft. 2. Maintenance precautions: During the initial stages of transmission repair, it is essential to diagnose the issue step by step based on the symptoms. Accurate judgment of the fault cause is crucial based on repair experience. Only by accurately identifying the problem and replacing or repairing the faulty internal components can the common transmission issues in Lexus vehicles be thoroughly resolved.
As a seasoned auto mechanic with decades of experience, I've handled numerous Lexus CVT transmission issues. Common faults include transmission overheating, frequently encountered during summer long-distance driving, leading to power loss or even engine stall; the most troublesome is the slipping sensation, where engine RPM surges but the car crawls, usually due to low hydraulic system oil pressure or steel belt wear; abnormal noises like humming or clicking indicate bearing or chain problems; electronic control module failures are also common, causing delayed or jerky shifting; occasionally, sensor failures render the transmission uncontrollable. For maintenance, I recommend changing the dedicated transmission fluid every 50,000 km, avoiding inferior products, and regularly inspecting the cooling system to prevent major repairs. Untreated faults can cost over ten thousand, with worse safety implications – imagine stalling on highways. In short, early detection and professional servicing save both hassle and money.
