What are the symptoms of AT transmission slipping?
2 Answers
The symptoms of automatic transmission slipping are as follows: 1. When starting and pressing the accelerator pedal, the engine speed increases quickly, but the vehicle moves slowly; 2. When the vehicle is going uphill or accelerating sharply, the engine speed is high, but the vehicle moves slowly. The causes of internal slipping in an automatic transmission are as follows: 1. Long-term lack of maintenance: The accumulated sludge, impurities, and metal powder can cause severe wear on the clutch, brake, or one-way clutch, leading to slipping. 2. Adding or replacing with non-specified oil: Automatic transmissions require vehicle-specific oil. If a different type of oil is used, if the friction coefficient increases, it may cause gear shift shock; if the friction coefficient decreases, it may cause slipping.
Last week when driving up the mountain, my AT transmission started slipping. I could clearly feel the engine RPM rising sharply, but the car speed just wouldn't increase, like it was in neutral revving in place. Acceleration became frustratingly sluggish. The gear shifts were constantly delayed too - what should have been smooth upshifts became jerky with the car body shaking, accompanied by an annoyingly high-pitched engine whine. I suspect it's either low or degraded transmission fluid, or possibly worn internal clutch plates. I need to visit the shop immediately to check fluid levels and try fresh fluid. Ignoring this could lead to complete transmission failure - a friend recently ignored similar symptoms and faced a 10,000+ repair bill. Regular maintenance is crucial. Safety first - now when I notice the issue I slow down early and pull over to avoid highway risks.
