Is It Harmful for an Automatic Transmission Car to Roll Forward in Reverse Gear?

[DiXavier]

Yes. It can cause impact to the chassis and driving system, with the most common issue being direct damage to the gears. In severe cases, the transmission may even be rendered unusable. Below are some parking precautions: 1. Basic parking principle: Consider both your own convenience for entry and exit as well as that of others, and also take into account potential unexpected situations. 2. Use turn signals when temporarily parking by the roadside: Always turn on the turn signal in advance when temporarily parking by the roadside, and check the rearview mirror to ensure there are no vehicles or pedestrians before pulling over. The parking location must be legally permissible and should not obstruct the passage of other vehicles or pedestrians. When parking due to traffic congestion or waiting at a traffic light, leave at least half a car length distance to prevent being trapped in the middle if the car in front breaks down. 3. Park in well-lit areas: Choose spacious and bright locations for temporary parking, and avoid hiding in corners. For long-term or overnight parking, always use a parking lot. Additionally, exercise extra caution and care when parking during severe weather conditions or on particularly crowded streets.

As a young driver just learning to drive, I remember one time when I parked on a slope and was too lazy to pull the handbrake, so I just shifted into R gear. The car actually rolled forward more than half a meter and almost hit a utility pole in front, which scared me into breaking out in a cold sweat. Later, a friend told me that this is extremely harmful to an automatic transmission. The gears would bear reverse pressure, leading to wear or even breakage, and repairs would cost at least several thousand yuan. Prolonged operation like this would greatly reduce the transmission's lifespan and could even lead to loss of control and accidents. Now I've developed the habit of always pulling the handbrake before shifting into P gear when parking. New drivers should remember this lesson to avoid trouble.

Having driven for nearly thirty years, I've witnessed numerous mechanical issues caused by rolling in reverse gear. This habit can easily damage the internal clutch plates and valve body of an automatic transmission, posing significant harm. Not only are the repair costs high, but it may also lead to safety accidents. Especially on slopes, even slow rolling can result in collisions with people or objects. My advice is to always ensure the brake is fully depressed and the handbrake is firmly engaged when parking. Cultivating this habit will save you trouble. There are no shortcuts to safe driving – mastery lies in the details.

A common complaint during car repairs is the transmission making abnormal noises after the vehicle rolls backward when shifting to R gear. This is quite harmful because the automatic transmission is designed with R gear for rear driving force. Rolling forward causes gear misalignment and accelerates wear. Repairs can cost at least 2000, which is quite expensive. The best prevention is to always pull the handbrake fully when parking—don't skimp on this effort.
