Common Faults of Changan Benben Automatic Transmission?

[LaMaya]

Changan Benben transmission failure may be caused by insufficient transmission oil or transmission oil leakage due to aging seals and poor sealing, or it could be due to transmission malfunction. Here are specific details about the transmission: 1. Structure: The internal control mechanism of an automatic transmission is very precise with small matching clearances, so it has high requirements for oil quality and must be kept clean. Over time, transmission oil can develop sludge and deposits, increasing wear on friction plates and components, which affects power transmission. 2. Maintenance Interval: Automatic transmission oil should generally be replaced every two years or 40,000 to 60,000 kilometers. After draining the old transmission oil, new automatic transmission oil should be added.

Having driven a Benben automatic transmission for five years, I have considerable experience with gearbox issues. The most common problem is jerky starts, especially during cold starts in low temperatures—it feels like being kicked from behind. Oil quality issues are particularly annoying; cars that have used cheap transmission fluid almost always experience delayed shifting. Oil leaks are also not uncommon, with stains often visible on the underbody guard. The most frustrating issue is solenoid valve failure—just two months ago, I had to repair it when the dashboard suddenly lit up with a yellow warning light, and the car got stuck in third gear and wouldn’t move. The repair shop later diagnosed it as valve body sticking, with the transmission fluid filter even turning black. A reminder to everyone: never delay repairs, as minor issues can escalate into a full transmission overhaul.

My BenBen just passed 30,000 kilometers and started acting up. The main automatic transmission issues occur at low speeds: when decelerating to 20 km/h, the car body jerks twice like going over speed bumps. The repair shop said it's caused by clutch plate wear leading to slippage, and fixing it requires dismantling the entire transmission. I've also experienced two instances of high oil temperature warnings, especially noticeable during summer traffic jams, which were later alleviated by installing an additional radiator. Actually, many malfunctions give early warnings – for example, metallic grinding sounds during gear shifts should prompt a transmission fluid check. I recommend new car owners change the fluid every two years to save significant repair costs. By the way, loose sensor connectors can also cause erratic gear shifting, which can be easily fixed by tightening them yourself.

The neighbor's auto repair shop often handles transmission issues with BenBen cars. The most common problem is acceleration slippage, where the engine RPM surges when stepping on the gas but the speed doesn't increase, which is usually due to insufficient oil pressure or a faulty torque converter. I've seen many cars with harsh shifting, mainly caused by valve body blockage or solenoid failure. Some can't engage reverse gear, and inspection reveals stuck shift cables. The most troublesome repairs involve internal bearing wear, as metal particles can contaminate the entire oil circuit system. A reminder to car owners: avoid keeping the car in D gear while braking at long traffic lights, as this can easily lead to excessive oil temperature.

My 2016 BenBen has experienced transmission issues twice. The first time there was a loud reverse gear noise - an extremely harsh metallic knocking sound. Diagnosis showed differential gear wear. The second failure was even scarier - sudden loss of power on the highway. Towing revealed a failed input shaft sensor. The blackened transmission fluid with a burnt smell clearly indicates problems, though I change the OEM fluid every 40,000 km. I've now learned to read trouble codes: P0700 indicates control module failure, P0730 means incorrect gear ratio - seeing these means immediate repair. Modified cars require special attention, as ECU-tuned vehicles are more prone to shift logic confusion.

All three company vehicles are Bennben automatics, and their common issues are quite predictable. New cars are most prone to gearshift jerks, especially noticeable hesitation during 2nd to 3rd gear shifts. Vehicles around three years old frequently trigger warning lights, with diagnostic codes mostly indicating RPM sensor problems. Older models require extra caution against oil pan leaks caused by deteriorated rubber gaskets losing sealing effectiveness. A lesser-known tip: Increased idle vibration transmitting to the steering wheel often stems from collapsed transmission mount bushings. Never underestimate regular maintenance – I strictly change fluid biennially, and at 80,000 km the transmission still operates smoothly. Beware during rainy seasons, as water exposure easily causes control module short-circuit failures.
