Why is the P gear flashing continuously?

[VanJoseph]

If the P gear of an automatic transmission car keeps flashing, it indicates a transmission malfunction and requires inspection and repair at a service station. Below is relevant knowledge about automatic transmissions: 1. Engine: The engine's power is transmitted through the transmission, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume over 10% more fuel than manual transmissions. Whether manual or automatic, more gears typically mean better fuel efficiency. 1. Automatic Transmission: It uses planetary gear mechanisms to shift gears automatically based on throttle pedal position and vehicle speed changes. The driver only needs to control the speed with the accelerator pedal. Common types of automatic transmissions in vehicles include: hydraulic automatic transmissions, hydrostatic automatic transmissions, electric automatic transmissions, stepped mechanical automatic transmissions, and continuously variable mechanical automatic transmissions.
