What to Do When a Mercedes-Benz Doesn't Move in D Gear?

[Allison]

Mercedes-Benz doesn't move in D gear for the following reasons: 1. The transmission fluid level is too low, or the internal oil pressure is too low. 2. The gear switch signal is incorrect. 3. There is a problem with the shift solenoid valve wiring or the solenoid valve itself. Here is an introduction to car gears: 1. R gear: Used when reversing, also called reverse gear. It is important to note that the car must come to a complete stop before shifting into R gear. 2. P gear: Used when parking, meaning the engine stops working. Therefore, many people call this gear the parking gear. 3. D gear: Mainly used for driving the car forward, called the drive gear, which is the basic gear of an automatic transmission car.
