What Causes the Gearbox of Song Pro to Jerk?

[OMadison]

Gearbox jerking is due to a dirty valve body, which can be resolved using a no-disassembly solution. Reasons for gearbox jerking: The primary cause of gearbox failure is often a dirty valve body. A dirty valve body can degrade the quality and frictional properties of the transmission fluid, increasing friction and wear. Additionally, sludge can form inside the gearbox, leading to blockages in the valve body and pipelines. This disrupts the proper regulation of oil pressure, resulting in gearbox issues. Solutions for gearbox jerking: Use a no-disassembly solution, which causes no damage to the vehicle. This method also extends the transmission fluid change interval by 3-5 times and effectively controls the temperature of the transmission fluid.

I've been driving for over a decade and have encountered many transmission stuttering issues, especially with this BYD Song Pro's dual-clutch transmission. The most common cause might be the transmission fluid not being changed for a long time, becoming thick or dirty, affecting the smooth operation of the gears. Or it could be that the clutch plates are severely worn, causing jerks or stutters during gear shifts. I've also encountered software issues where the control unit wasn't updated properly, leading to slow engine response or strong jerking sensations. Additionally, if the car has been driven on rough terrain, such as muddy roads or long downhill slopes, dust entering the drivetrain can also cause stuttering. My advice is not to panic; first, check the fluid condition or visit a 4S shop for diagnostics—they can use equipment to pinpoint the exact issue. During daily driving, avoid slamming the accelerator and try to accelerate smoothly to protect the transmission, which can extend its lifespan. If the stuttering is severe, pull over to ensure safety before addressing the problem. Overall, the transmission is a precision component, and regular maintenance is key.

As a young car owner, what I care most about is the daily driving experience. The gearbox stuttering issue in the Song Pro is likely related to its dual-clutch design, such as rough shifting at low speeds or the dragging sensation caused by repeated start-stop movements in city traffic jams. I think common causes include poorly updated software, sluggish control system response; or hardware issues like gear set gaps/looseness, and incomplete oil changes which can easily lead to stuttering. It's especially noticeable during significant temperature changes - whether during hot weather or cold starts. Don't underestimate minor issues, address them early to avoid accidents. I recommend using an OBD scanner with your phone to check for error codes, and frequently consult the maintenance schedule in the user manual. Warm up the transmission for a few minutes before driving to let it adapt, and keeping it in eco mode can also reduce impact. It's best to schedule an appointment with professional technicians who can fine-tune the control program. In short, paying attention to your vehicle's condition details brings both peace of mind and trouble-free driving.

Every time I drive my child to school, the occasional jerk in the Song Pro's transmission always makes me nervous. I figure it's probably due to a few simple reasons: insufficient or degraded transmission fluid leading to poor lubrication and gear grinding; misaligned sensors causing signal deviations; or worn-out clutch components resulting in delayed shifting. Safety first—I immediately pulled over to check, avoiding forced driving to prevent loss of control. I make it a habit to change the oil and filters on schedule and regularly check the transmission fluid level. While driving, I avoid sudden acceleration or overloading to reduce strain on the transmission. If the jerking becomes frequent, I’ll take it to a repair shop for a computer system scan. With proper maintenance, the car runs smoothly, and that gives me much more peace of mind.
