What are the causes of transmission noise in the Roewe RX5?
2 Answers
Roewe RX5 experiencing transmission noise may be caused by insufficient or low-quality oil that does not meet the vehicle's specified standards, or improper maintenance leading to noise. Upon discovering any damage, timely repair of the Roewe RX5 transmission is necessary to completely resolve the issue. Below is a brief introduction to transmissions: 1. Classification of transmissions: Transmissions are divided into manual transmissions and automatic transmissions. Manual transmissions consist of gears and shafts, while automatic transmissions are composed of hydraulic torque converters, planetary gears, etc. 2. Development and reform of transmissions: With the continuous development of the automotive industry, transmissions have evolved from manual to automatic. Transmissions allow the car to move backward without changing the engine's rotation direction, and shifting to neutral can interrupt power to enable engine start and gear shifting. Owners using automatic transmissions can easily drive the car, and compared to manual transmissions, automatic transmissions are less prone to malfunctions.
My Roewe RX5 has been running for four or five years, and the clunking sound when the transmission shifts has been driving me crazy. A veteran mechanic checked it and said there are mainly three possible causes: the wear of the dual-clutch module is the prime suspect—this dry dual-clutch has poor heat dissipation, and frequent shifting in city traffic jams makes it particularly prone to problems; secondly, the transmission oil has failed—if not changed for a long time, the viscosity drops, and insufficient lubrication of the gears leads to dry grinding and noise; another hidden issue is a fault in the valve body control, where incorrect shifting signals cause poor gear engagement. I must remind everyone not to ignore such abnormal sounds—last time, my neighbor’s gear synchronizer was completely worn out, and the major repair cost over 8,000 yuan.
