What are the signs of a failing transmission in the 2016 Sylphy?
2 Answers
Signs of a failing transmission in the 2016 Sylphy include transmission slipping, oil leakage, jerking, abnormal noises, excessive oil temperature, and engine stalling after shifting gears. Below are detailed explanations of these signs: 1. Transmission slipping. While driving, if you hear the engine revving without a noticeable increase in speed or acceleration, or experience difficulty climbing hills with an unexplained rise in engine rpm while normal on flat roads, it may indicate slipping. Possible causes are excessively high hydraulic oil levels generating foam from intense stirring by planetary gears, or worn/burnt clutch or brake friction plates. 2. Transmission oil leakage. You may notice difficulty starting the vehicle, and while the engine rpm increases when accelerating, the car doesn't speed up accordingly. This could be due to oil leakage, which reduces internal lubrication and hampers transmission operation. 3. Transmission jerking. During driving, you may feel obvious jerks or shaking when shifting gears. This could result from excessive transmission oil temperature, internal stubborn dirt and impurities causing blockages in the valve body, leading to jerking. 4. Transmission abnormal noises. While driving, inexplicable noises from the transmission may occur, with no identifiable source, sometimes loud, and appearing intermittently during gear shifts. The causes are complex, possibly due to reduced anti-wear and lubrication performance of transmission oil under prolonged high temperatures, leading to wear or damage in bearings and gears. 5. Excessive transmission oil temperature. The onboard computer may display an overheating transmission temperature during driving, and you might feel it's hot to the touch. This often results from transmission slipping or failed temperature control under high loads, and in some dual-clutch transmissions, from heat generated by clutch plate friction. 6. Engine stalling after shifting gears. When shifting from P to D, the engine may stall immediately. Possible causes include stuck or damaged solenoid valves, lock-up control valves, or faults in the input shaft speed sensor.
I've been driving a 2016 Sylphy for several years, and its CVT transmission shows quite noticeable early warning signs of common issues. If you feel jerking or hesitation during gear shifts—like the car responds sluggishly when you press the accelerator—it could signal internal wear in the transmission. Sometimes, there's a buzzing or grinding noise during acceleration, especially on mountain roads or uphill climbs. I've also experienced unstable speed, where the car suddenly slips or loses traction at certain speeds, making it feel like it can't grip the road. Additionally, if the transmission warning light on the dashboard comes on, pay immediate attention; or if you spot oil leaks under the car, it indicates aging seals causing low pressure. Early detection can prevent breakdowns. During every maintenance session, I remind the mechanic to check the transmission fluid—regular upkeep and safe driving habits are key to extending its lifespan.
