When a transmission malfunctions, the car can suddenly lose power or handle imprecisely, which puts you in danger on the road. Always respond quickly to the early warning signs of gearbox problems. If you experience the six issues below, get immediate transmission service at your Toyota dealership. Burning Fluid Smells Most transmission faults come down to the fluid. Transmission fluid lubricates the planetary gear systems and also maintains a high level of hydraulic pressure. Despite being very long-lasting, transmission fluid eventually starts to degrade and diminish, especially if it overheats or leaks. As transmission fluid problems develop, friction rises and the fluid starts to burn. You may smell this from the cabin above. more Clunking or Grinding Sounds The complex systems inside your transmission will emit odd clunking or grinding if the fluid's low or an important part has worn out. Issues with the gears, clutch, or torque converter might all cause metallic grinding noises. Automatic transmissions sometimes also whine or hum when in trouble. Vibrations and Jolting With low transmission fluid, friction builds and gears stop running as smoothly together, which causes vibrations. If something is interfering with gear engagement, your car might also jolt and shudder when you try to shift gears. Delayed Gear Engagement It's never a good sign when gears don't change promptly and seamlessly. Hesitant engagement means the transfer of power between the engine and wheels is momentarily cut. This may cause the engine to rev loudly while your car accelerates only sluggishly or slows down. You might then jolt forward when the new gear finally engages. Suddenly Slipping Gears It's even worse when a transmission slips and shifts on its own. Slipping gears can be due to rounded out gear teeth, low or contaminated fluid, faulty transmission bands, worn clutch plates, or issues with the solenoids. If your gears begin to slip, the transmission could stop shifting altogether as a protective measure until the fault is repaired. Dripping Puddles of Fluid Never ignore even a small puddle of fluid under your car. If transmission fluid is leaking, it's unwise to drive until you've had the leak fixed and the fluid topped up. Such a leak might originate from a cracked cooler line, a broken seal, a loose drain plug, or a damaged torque converter.
