Possible causes of noise in the Hyundai Solaris transmission with automatic transmission:
1. Insufficient transmission fluid level: Low fluid levels can cause insufficient lubrication of transmission components, causing noise.
2. Contaminated Transmission Fluid: Over time, transmission fluid becomes contaminated with wear particles and other debris, which can lead to noise and shifting problems.
3. Worn or damaged bearings: Worn bearings can create noise, especially when the transmission is under load or when shifting gears.
4. Inoperative oil pump: The oil pump is responsible for circulating transmission fluid in the gearbox. A faulty oil pump can lead to poor lubrication and noise.
5. Broken Teeth: Worn or broken gear teeth in a transmission can create significant noise and cause shifting problems.
6. Defective torque converter: The torque converter converts engine power into rotation for the transmission. A faulty torque converter can create noise and shifting problems.
7. Worn Clutches: Over time, the clutches used to transfer power to the wheels can wear out, which can create noise and shifting problems.
Troubleshooting steps:
* Check the level and condition of the transmission fluid.
* Replace transmission fluid and filter if dirty.
* Inspect the transmission for leaks or damage.
* Run diagnostics to determine the specific cause of the noise.
* Take the car to a car service center to eliminate any identified problems.
