What is the reason for the jerking in the Besturn B50 transmission?

The reason for the jerking in the Besturn B50 transmission is the presence of stubborn dirt and impurities inside, especially when these accumulate in the valve body, forming blockages that prevent effective regulation of oil pressure, leading to jerking, impact, and slippage issues. The problem of high transmission temperature should not be overlooked either. Under high-temperature conditions: High temperatures can degrade the quality and friction characteristics of automatic transmission fluid, increasing friction and wear, which leads to transmission noise. At the same time, sludge (impurities or dirt) can form inside the transmission (such as in the valve body), causing jerking and impact. If the temperature exceeds 120 degrees Celsius, rubber sealing materials will begin to harden, eventually leading to leaks and reduced hydraulic pressure. If the temperature rises even higher, the transmission will start to slip, and this slippage will, in turn, cause the temperature to rise further. If not addressed promptly, the transmission will be ruined. Solution: To completely resolve transmission issues and prevent their recurrence, it is necessary to remove stubborn dirt and impurities from the transmission and effectively control the transmission's operating temperature.

As a veteran driver of the Besturn B50, I've also encountered transmission jerking issues. When driving in stop-and-go city traffic, I often felt the car lurching during gear shifts, which was quite uncomfortable. After some research, I learned it might be due to old or deteriorated transmission fluid, as delayed oil changes can affect shifting smoothness. It could also be caused by worn clutch components leading to uneven power delivery. Another possibility is a faulty control module where unstable sensor signals cause poor computer adjustments, resulting in jerking. My advice is to monitor the dashboard for warning lights while driving. If jerking occurs frequently, don't delay—visit a professional shop immediately to check fluid levels and condition. Often, a fluid change solves the problem. Prolonged neglect can damage components and lead to higher repair costs. Never attempt DIY repairs without proper knowledge; always seek diagnosis from qualified technicians for safety.

Driving a B50 with transmission jerks is quite annoying, feeling like being kicked during gear shifts, which is really uncomfortable. I've done some research on cars, and the main issues could be insufficient or contaminated fluid. Transmission oil is responsible for lubrication and power transfer; when it's dirty, it causes abnormal friction in components. Another possibility is wear and tear in internal mechanical parts like the valve body or planetary gears, which naturally develop problems over time. If the car has a software issue, the control unit misjudging the shift points can also cause jerks. Pay attention to the frequency of jerks during daily driving, such as being more noticeable at low speeds. My friend's car had this issue, and after inspection, it turned out to be a faulty oil temperature sensor. Don't just guess and take it to a small shop for random repairs; timely inspection can save a lot of trouble. Regular maintenance of fluids is key—it's recommended to change the oil every few tens of thousands of kilometers.

The Besturn B50 transmission jerks and feels sluggish when driving, especially during acceleration and deceleration. This is often due to aging transmission fluid or the accumulation of impurities, which increases friction between components. Alternatively, sensor failures, such as a malfunctioning speed sensor, can cause the transmission to respond sluggishly. If the jerking occurs frequently, it can affect driving safety, potentially causing dangerous delays during emergency acceleration. When I noticed this issue with my car, I immediately checked the fluid level and condition, as preventive maintenance can avoid costly major repairs. Timely action is crucial.
