What are the reasons for the noise when shifting from P to R gear?

[VanConnor]

The reasons for the noise when shifting from P to R gear are as follows. Shift solenoid valve malfunction: It is usually caused by a faulty or clogged shift solenoid valve. Shift precautions: After shifting into a new gear, release the clutch pedal smoothly and timely. The coordination between the clutch pedal, accelerator pedal, and gear lever should be correct and harmonious, with accurate positioning. The action should be swift to minimize shift time, reduce kinetic energy loss of the vehicle, and lower fuel consumption. Master the appropriate shift timing, meaning neither upshifting too early nor downshifting too late. Shifting should be determined based on the vehicle speed. You can increase the speed before upshifting and decrease the speed before downshifting. It is important to note that when downshifting, to prevent mechanical wear, it is best to use the double-clutching method for downshifting.
