What is the Solution for the Abnormal Noise in the Sagitar Transmission?
3 Answers
The solutions for the abnormal noise in the Sagitar transmission are: 1. Replace the bearings; 2. Tighten the transmission housing screws; 3. Replace the transmission oil; 4. Replace the gears inside the transmission. Transmission working principle: 1. Manual transmissions consist of gears and shafts, achieving speed and torque variation through different gear combinations; 2. Automatic transmissions are composed of hydraulic torque converters, planetary gears, and hydraulic control systems, achieving speed and torque variation through hydraulic transmission and gear combinations. Types of transmissions include: 1. Hydraulic automatic transmission; 2. Continuously variable transmission (CVT); 3. Electro-mechanical automatic transmission.
I've fixed many transmission noise issues in Sagitars, and the main causes could be insufficient transmission fluid or dirty, thickened oil leading to poor lubrication and severe noise. First, check the dipstick—if the level is low, top it up with new oil of the correct specification. If the noise persists after refilling, it might be due to gear wear or loose bearings, especially common with manual transmission clutch discs. Dual-clutch transmissions are more prone to wear and produce clicking sounds during frequent gear shifts in traffic jams. It's best to use a diagnostic scanner to confirm the fault code and pinpoint the issue. Minor problems like fluid changes can be DIY fixes, but if that doesn't work, seek a professional repair shop. Don't delay until parts are completely damaged, requiring a costly overhaul or total replacement costing thousands. Regular maintenance, such as changing the oil every 40,000 km, can prevent this.
Last year, my Sagitar's transmission started making strange noises, with an annoying humming sound when pressing the accelerator. I thought it was a minor issue and ignored it, but the noise grew louder. After taking it to the 4S shop, the technician found insufficient oil mixed with impurities. After replacing the transmission fluid and cleaning the system, it became much quieter. They mentioned that aging components like the clutch or faulty sensors could also cause noises, requiring inspection or even replacement. I suggest fellow car owners check and top up the oil level promptly if they hear any abnormalities. For complex issues like internal wear, it's best to leave them to the experts. Don't follow my example of delaying repairs—early resolution saves both hassle and money. Driving smoothly and avoiding sudden acceleration in daily use can protect the transmission and extend its lifespan.
