Why does the car move forward when in R gear?

Because the computer automatically judges the current road conditions and switches to the appropriate gear. The following is a related introduction about vehicle gear shifting: 1. Precautions: When downshifting, the method of two-clutch and one-empty throttle should be used. The principle of downshifting with an empty throttle is: the faster the speed, the larger the "empty throttle"; the slower the speed, the smaller the "empty throttle"; the lower the engine speed, the larger the "empty throttle"; the higher the engine speed, the smaller the "empty throttle"; on flat roads, the "empty throttle" is larger, while uphill, the "empty throttle" is smaller. 2. Tips: Gear shifting should be timely, correct, smooth, and quick. When starting the car, generally use the low gear (first gear). After starting, as long as the road conditions permit, quickly and timely shift up to higher gears.
When the car moves forward in reverse gear (R), I must say, after working in a repair shop for many years, I've seen quite a few similar issues. The most common cause is internal transmission damage, such as worn gears getting stuck in a forward gear and failing to disengage. Another frequent issue is loose or corroded linkage in the shift mechanism, preventing the gear lever from truly engaging the reverse position. For automatic transmissions, malfunctions in the torque converter or hydraulic system can also easily cause this kind of confusion. I strongly advise you to stop driving immediately—having the car lurch forward while in reverse is extremely dangerous, especially on slopes or in tight parking spaces, as it can lead to collisions or even rollovers. Take it to a professional repair shop as soon as possible; you may need part replacements or linkage adjustments. For prevention, regularly changing transmission fluid and checking shift smoothness can significantly reduce risks. Don’t wait until problems arise—fixing them later costs more money and hassle. Driving safety comes first, especially with older vehicles where these details matter most.
As an ordinary car owner, I once experienced my old car moving forward when I shifted into reverse gear. It almost hit a wall in the parking lot, which really gave me a scare. After inspection, it turned out that the linkage of the gear shift lever was loose, causing it not to lock firmly into the reverse gear position when shifted to R. The repair shop simply tightened it for me, costing less than 200 yuan. If you encounter a similar issue, don't panic. First, ensure the vehicle is stationary with your foot on the brake, then check if the gear lever is accurately in position. For manual transmissions, remember to fully depress the clutch. For safety, I recommend getting into the habit of rolling down the window to listen for sounds or installing a rearview camera when reversing. Such malfunctions often occur frequently in aging vehicles. I suggest having the technician inspect the gear shift mechanism during every maintenance session to avoid future troubles. Here's a tip: regular maintenance saves a lot more money than emergency repairs.
