What are the causes of abnormal noise in the Leiling Hybrid transmission?

[LeAddyson]

Leiling Hybrid transmission abnormal noise is caused by bearing wear, looseness, or constant meshing gear noise; poor gear meshing inside the transmission; the specific causes and solutions for vehicle transmission abnormal noise are as follows: Bearing wear, looseness, or constant meshing gear noise: If abnormal noise is heard from the transmission in neutral, and the noise disappears when the clutch is depressed, it is generally due to wear, looseness of the front and rear bearings of the transmission first shaft, or constant meshing gear noise. If abnormal noise occurs when shifting to other gears, it is mostly due to noise from the rear bearing of the second shaft. For severely loose or damaged bearings, they should be promptly sent to a repair shop for maintenance or replacement. Poor gear meshing inside the transmission: If abnormal noise occurs in the transmission during low-speed driving, and it still appears after vehicle acceleration and when shifting gears, it may be caused by poor gear meshing inside the transmission. Generally speaking: if the noise is small and uniform, the vehicle can still be used; if the noise is uneven and very loud, the transmission should be disassembled for inspection, and repaired or replaced.

When I first drove the Leiling Hybrid, I encountered transmission noise, mainly hearing a clicking sound during low speeds or sudden acceleration. It might be due to wear in the clutch unit, as the e-CVT structure in hybrids is complex, and prolonged friction can thin the clutch plates, causing noise. Additionally, a malfunction in the hydraulic control system could also produce sounds, as unstable oil pressure may cause parts to collide. I recall insufficient lubrication is another common factor—aged or degraded fluid fails to protect internal gears. If the motor bearings, unique to hybrids, are damaged, the noise can transmit to the transmission area. Once you hear such sounds, get it checked immediately—don’t let a minor issue turn into a major repair. At the dealership, the technician used computer diagnostics to pinpoint the root cause. They recommended checking fluid conditions and running system scans during biannual maintenance to save hassle later.

My Corolla Hybrid had noticeable abnormal noises last time, especially when going uphill. I discussed this with a friend, and he said this phenomenon is quite common. I suspect the main issues could be loose planetary gears or chain wear. The hybrid transmission has a unique design, and long-term vibrations can cause fatigue in these parts. Another possibility is oil pump issues leading to insufficient lubrication and friction noises. I learned some basic checks online, such as verifying the oil level is normal and checking for any signs of leakage. If it's an electrical fault, like a malfunctioning control module, it might also be accompanied by delayed gear shifts. I recommend promptly visiting a repair shop for professional diagnostics instead of attempting DIY fixes. Hybrid systems are more complex, and ignoring abnormal noises could lead to bigger problems, such as motor damage, which would be more expensive to repair. Driving smoothly in daily use can help reduce wear and tear.

With years of research in automobiles, I've found that the sources of abnormal noises in the Leiling Hybrid's transmission are mostly inside the e-CVT. For example, worn bearings in the generator or drive motor can produce squeaking sounds; loose planetary gear chains result in clicking noises. The hybrid system relies on electronic units to control shifting, so sensor failures may also generate noise; insufficient lubrication increases friction, leading to frequent abnormal sounds. It's recommended to use a diagnostic tool to read error codes for pinpointing the issue.
