What causes the transmission failure in Haval F7?
3 Answers
Haval F7 experiencing transmission failure mainly occurs when the vehicle suddenly shifts into neutral at low speeds during driving. The best solution is to stop the car, turn off the engine, and then restart the vehicle. Transmission oil leakage: The first type is transmission oil leakage, where oil seeps out from the transmission housing or oil pan. This may be caused by aging seals leading to poor sealing, or manufacturing defects resulting in porosity in the housing. Engine stalling when engaging gear: The second type is engine stalling, no response, or jerking when the transmission is engaged. The stalling issue when engaging gear is more noticeable when the engine is cold. This problem could be caused by transmission issues or other vehicle system problems. Engine stalling when shifting into D or R: The third type is engine stalling when shifting into D or R gear. This situation may be caused by a damaged lock-up solenoid valve or a stuck lock-up control valve when engaging D or R gear.
As someone who has been repairing cars for years, I can tell you that the Haval F7 transmission has quite a few common failure causes. If the transmission fluid is low or dirty, poor lubrication can easily lead to gear shifting hesitation or failure. Then there are sensor failures, like a faulty gear position sensor—if the computer can't read the signal accurately, the car won't know how to shift gears. Mechanical components, such as worn clutch plates or deformed gears, naturally develop issues over time. Additionally, if the electronic control module fails, the entire transmission logic gets disrupted. Driving habits also play a role—frequent acceleration and hard braking can accelerate wear. My advice is to first check the color and level of the transmission fluid—it's a simple task. If that doesn't solve the issue, take it to a professional shop to read the trouble codes with a diagnostic tool. After all, if the transmission fails, sudden stalling while driving can be extremely dangerous. Don't delay—safety first.
Last time I drove a Haval F7, I also had transmission issues—it suddenly got stuck while shifting gears. Probably because I didn't change the oil regularly, and the degraded oil accumulated impurities that clogged the lines. I'm used to driving fast, with sharp turns and sudden stops, which also accelerates component wear. The mechanic mentioned it could also be due to loose sensors or faulty computer control, disrupting signal transmission. I usually don’t understand these things, but for minor issues, checking fluids and connectors first can save money and hassle. If the car won’t shift or jerks severely, don’t force it—pull over immediately. Otherwise, breaking down mid-drive is a huge hassle, and towing it to the shop is the way to go.
