What are the symptoms of CVT transmission slipping?
2 Answers
The symptoms of CVT transmission slipping are as follows: 1. When pressing the accelerator to accelerate, you may notice the engine speed increases, but the vehicle speed does not rise accordingly, generally resulting in sluggish acceleration. 2. Sensors on the transmission drive shaft monitor the speed. If the transmission slips severely, a warning light will illuminate on the dashboard. If the dashboard warning light comes on, it is necessary to visit a 4S store for inspection and repair. The advantages of a CVT transmission are as follows: 1. Excellent driving experience: Since there is no gear-shifting process like in an automatic transmission, there is no jerky sensation from shifting. The power delivery of a CVT transmission is linear, making the driving operation very smooth. 2. The gear settings of a CVT transmission are relatively flexible: It is easier to achieve a balance between performance, fuel consumption, and emissions during driving. 3. CVT transmissions have high mechanical efficiency and good fuel-saving performance.
I've been driving a CVT car for several years, and the most obvious symptom when encountering transmission slippage is that the engine speed surges extremely fast when stepping on the accelerator, as if it's about to take off, but the car accelerates slowly and feels sluggish and powerless. When going uphill or under heavy load, there may also be insufficient power, or even rolling back. Sometimes, abnormal noises from the transmission during driving, such as buzzing or friction sounds, can be quite annoying. Fuel consumption also increases, burning significantly more fuel for the same distance compared to before. I've concluded that this is mainly caused by wear of the CVT belt or unstable oil pressure due to aging transmission fluid. If not addressed in time, small issues can turn into big troubles. It's recommended to check the transmission fluid level and condition every 10,000 to 20,000 kilometers. Once these signs are noticed, it's best to seek professional repair as soon as possible. Safe driving is crucial, so never ignore these small signals.
